Paleontology portal History of science portal Dinosaurs portal Paleontology or palaeontology (from Greek: paleo, "ancient"; ontos, "being"; and logos, "knowledge") is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 2016.

Trace fossils are those details preserved in rocks that are indirect evidence of life. While we are most familiar with relatively spectacular fossil hard remains, such as shells and bones, trace fossils are often less dramatic, but nonetheless very important. Trace fossils include burrows and other dwelling structures, track marks (such as footprints or evidences of creeping or crawling), coprolites (fossilized feces), eggs and eggshells, nests, rhizoliths or rhizocretions (fossil remains of roots), and other types of impressions. Fossilized droppings, called coprolites, can give insight into the feeding behavior of animals and therefore can be of great importance.. The study of trace remains is called ichnology, which is divided into paleoichnology, or the study of trace fossils, and neoichnology, the study of modern trace remains. Another name for trace fossils is ichnofossils, taken from the Greek word "ichnos," meaning "trace." The science of ichnology is quite challenging, as many trace ...

Weve got the lineage of the hobbit, Homo floresiensis (in quotation marks because its human status in not yet clear), perhaps diverging more than two million years ago, evolving in isolation in southeast Asia, and apparently going extinct about 17,000 years ago.. Weve got Homo erectus, most likely originating in Africa, giving rise to lineages which continue in the Far East in China and Java, but which eventually go extinct. In Europe, it perhaps gave rise to the species Homo antecessor, "Pioneer Man," known from the site of Atapuerca in Spain. Again, going extinct.. In the western part of the Old World, we get the development of a new species, Homo heidelbergensis, present in Europe, Asia and Africa. We knew heidelbergensis had gone two ways, to modern humans and the Neanderthals. But we now know because of the Denisovans that actually heidelbergensis went three ways-in fact the Denisovans seem to represent an off-shoot of the Neanderthal lineage..

Outdoor enthusiasts often put a lot of consideration into where they want to go on their next great adventure. They may want to go to a climate different from the one they live in throughout the year, or simply someplace with majestic sites and natural challenges. One place that doesnt make very many top 10 lists is the Badlands of South Dakota. Even the name Badlands seems to suggest that nothing good can be found there. However those who have blazed the trail of the Black Hills know that a vacation in the Badlands is nothing but good.. The Big Pig Dig. One of the most amazing sights in the Badlands National Park is a huge crater dug among the natural vistas. Known as the "big pig dig", this crater has produced over 13,000 fossils and is the site of one of the most ambitious paleontology digs in the world. Visitors are always welcome and at certain times of the year are allowed to accompany students and scientists onto the dig site to look for fossils and learn the procedures of paleontology. ...

Another project done by Maria and Izzy focused on the correlation between body size and chewing rate. For data collection, Maria and Izzy measured the chewing rate of various herbivores. Along with the help of the other students, Izzy and Maria were able to collect an average chewing rate from 5 domesticated species found in Ileret. To predict the body size of the various herbivores, they also measured the length of the second molar (M2) from skulls in the lab. By putting together both the chewing rate and the body size estimates, they were able to see the relationship between chewing rate and body size for all 5 species.

In 1927, Simpson took a position as assistant curator in vertebrate paleontology at the American Museum of Natural History and in 1928, was promoted to associate curator. By 1932, Simpson was formally separated form Lydia and had custody of one daughter, Helen, while one daughter lived with the maternal grandmother, and his two other daughters with Lydia were under her custody (Laporte 2007c). However, in late 1932, Lydia was committed to a mental hospital and Simpsons parents cared for these two daughters. Lydia had had a history of mental problems even before meeting Simpson (Laporte 2007b). In 1932, Simpson began to live with Anne Roe, a childhood friend, who also had obtained a Ph.D., from Columbia University in psychology, and had divorced her husband in 1932. Simpson would gain a divorce from Lydia in April 1938, and marry Anne a month later (Laporte 2007b).. In 1942, Simpson became the first elected President of Society of Vertebrate Paleontology. In 1942, after the Director of the ...
anteroposteriorly adj., an anatomical term for the front part of a bone or organ in the back. For example; The leading edge of a phalange number five is the front edge of the last finger bone in the paddle of a plesiosaur. This term is used a great deal but is far too arbitrary as it could be made to refer to anything.that is in a skeleton or on any organ. You can use it to reference what layer of skin lays in relation to another. So the last layer of epithelial cells has a leading edge to the last layer so that back edge becomes anterioposterior to the side that follows. Because of the confusion and arbitrariness the term is better off being discarded; it is only included here as a refernece for when it appears in quoted material ...

By Iqbal Pittalwala, University of California - Riverside Likely related to our ancestors, Plexus ricei was much like a tapeworm or modern flatworm, say UC Riverside researchers. Scientists at the University of California, Riverside have discovered a fossil of a newly discovered organism from the "Ediacara Biota" - a group of organisms that occurred in the Ediacaran period of geologic time.. Named Plexus ricei and resembling a curving tube, the organism resided on the Ediacaran seafloor. Plexus ricei individuals ranged in size from 5 to 80 centimeters long and 5 to 20 millimeters wide. Along with the rest of the Ediacara Biota, it evolved around 575 million years ago and disappeared from the fossil record around 540 million years ago, just around the time the Cambrian Explosion of evolutionary history was getting under way.. "Plexus was unlike any other fossil that we know from the Precambrian," said Mary L. Droser, a professor of paleontology, whose lab led the research. "It was bilaterally ...
Fossils are the preserved remains of plants or animals. For such remains to be considered fossils, scientists have decided they have to be over 10,000 years old. There are two main types of fossils, body fossils and trace fossils. Body fossils are the preserved remains of a plant or animals body. Trace fossils are the remains of the activity of an animal, such as preserved trackways, footprints, fossilized egg shells, and nests.. When asked what a fossil is, most people think of petrified bones or petrified wood. Permineralization is a process. For bone to be permineralized, the body must first be quickly buried. Second, ground water fills up all the empty spaces in body, even the cells get filled with water. Third, the water slowly dissolves the organic material and leaves minerals behind. By the time permineralization is done, what was once bone is now a rock in the shape of a bone.. When an animal or plant dies, it may fall into mud or soft sand and make an impression or mark in the dirt. ...
Earlier this year, ICR published a beautifully illustrated book entitled The Fossil Record: Unearthing Natures History of Life, co-authored by ICR Senior Science Lecturer Frank Sherwin and myself. Although it is not intended to be a textbook on paleontology, the study of fossils, it does provide important supplemental information that helps in understanding their basic message. It consists of two sections-a laymans summary and an extensive appendix on supposed transitional fossils.. Both sections were written with Christian students in non-scientific majors in mind. We recognized that far too many Christian young people in high school and college leave the faith when they are confronted with an evolutionary interpretation of fossil evidence, having often received little training at home or in church to counter it. We desired to help stem those losses and provide Christians with practical answers they could use. The books main portion covers evolutionary claims that are likely to be discussed ...

The work was carried out by a University of Bristol student, working with an international team of researchers. The research was published online in Quaternary International.. Today, elephants live only in remote, tropical parts of Africa and southern Asia, but before the Ice Ages they were widespread.. As his undergraduate research project, Zhang Hanwen, MSci Palaeontology and Evolution graduate and now PhD student at the University of Bristol, undertook cutting-edge analysis of fossilised elephant teeth from China.. In a collaboration with the University of Leicester, and the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, where the fossilised teeth are curated, Hanwen sampled 27 teeth for tiny wear patterns called microwear.. "We are talking huge, brick-sized molars here - the largest of any animal," said Hanwen, "but the signs of tooth wear are tiny, down to thousandths of a millimetre. However, these microscopic surface textures can tell us whether they were eating ...
Cal State Fullerton graduate student Gabriel-Philip Santos has uncovered a fossil from Orange County - an 8-to-13 million-year-old member of an extinct group of herbivorous marine mammals called desmostylians, a hippo-like looking animal.. For the past three years, Santos has studied the fossil, a partial jaw of the desmostylian, found in 1996 during construction of the State Route 241 toll road, near Mission Viejo. Santos research focuses on the age and growth of desmostylians, revealing that the John D. Cooper Archaeological and Paleontological Center fossil specimen is an individual that lived to an old age - the most elderly ever found.. "We dont know how many birthdays this desmostylian had, but based on its lost teeth, there is evidence that the animal was able to survive into old age," said James F. Parham, assistant professor of geological sciences and faculty curator of paleontology at the Cooper Center, a partnership between CSUF and OC Parks.. "Since scientists have yet to find a ...

For the first decade after the paper was published, it was the most controversial and hotly argued idea in all of paleontology. Soon the great debate among paleontologists boiled down to just a few central points, which Gould and Eldredge (1977) nicely summarized on the fifth anniversary of the papers release. The first major discovery was that stasis was much more prevalent in the fossil record than had been previously supposed. Many paleontologists came forward and pointed out that the geological literature was one vast monument to stasis, with relatively few cases where anyone had observed gradual evolution. If species didnt appear suddenly in the fossil record and remain relatively unchanged, then biostratigraphy would never work-and yet almost two centuries of successful biostratigraphic correlations was evidence of just this kind of pattern. As Gould put it, it was the "dirty little secret" hidden in the paleontological closet. Most paleontologists were trained to focus on gradual ...
Every now and then it occurs to me just how silly vertebrate palaeontology is. Consider the following: access to specimens is extremely competitive, but, despite this, a vast wealth of material remains undocumented; chances of scoring funding are less than 5 per cent; a high proportion of the work you perform is unpaid; there are all sorts of political considerations when reporting new finds or sharing information and, aside from being nice to know, theres very little reason or rationale to investigate most extinct vertebrates - invertebrates and microfossils have utility in stratigraphy and hydrocarbon work, at least. All the same, people are falling over themselves to work in this profession, which means you have to be bristling with qualifications to even think of applying for an academic palaeo position. These qualifications dont come cheaply: in Britain, youre looking at three years of a relevant degree study, probably another year earning a Masters, then at least another three of PhD ...

1. Cenozoic evolution of grasses and grazers. The evolution of grassland ecosystems was one of the most profound ecological changes of the past 65 million years, but many questions remain as to when it occurred and what triggered it. A traditional, yet untested assumption is that many animals (e.g., horses, dung beetles) evolved in lockstep with the spread of grass-dominated vegetation. I investigate these questions by using a novel source of paleobotanical data, plant silica (phytolith), integrated with information from, for example, sedimentology, modern ecology, plant anatomy, and vertebrate paleontology. This work entails paleontological and geologic fieldwork in areas such as the North American continental interior, the Pacific Northwest, Argentina, Turkey, Spain, and China, laboratory work, as well as systematic, statistical, and phylogenetic analysis. Many of these projects involve international collaborators including from Duke University, Geologic Survey of Turkey, Utrecht University, ...
Sampson had continued his studies of the material since 1989. In 1994, in a talk during the annual meeting of the Society of Vertebrate Paleontology, he named "Taxon C" as a new genus and species, Achelousaurus horneri. Although an abstract was published containing a sufficient description, it did not identify a holotype, a name-bearing specimen.[24] In 1995, in a subsequent article, Sampson indicated specimen MOR 485 as the holotype specimen of Achelousaurus horneri. The generic name consists of the words Achelous, the name of a Greek mythological figure, and saurus, which is Latinized Greek for lizard. Achelous (Ἀχελῷος) is a Greek river deity and a shapeshifter who was able to transform himself into anything. During a fight with Hercules, the mythical hero, Achelous took the form of a bull, but lost the battle when one of his horns was removed. This allusion is a reference to the supposedly transitional traits of the dinosaur and the characteristic loss of horns through ontogenetic ...
Since the 1980s, a renewed understanding of molecular development has afforded an unprecedented level of knowledge of the mechanisms by which phenotype in animals and plants has evolved. In this volume, top scientists in these fields provide perspectives on how molecular data in biology help to elucidate key questions in estimating paleontological divergence and in understanding the mechanisms behind phenotypic evolution. Paleobiological questions such as genome size, digit homologies, genetic control cascades behind phenotype, estimates of vertebrate divergence dates, and rates of morphological evolution are addressed, with a special emphasis on how molecular biology can inform paleontology, directly and indirectly, to better understand lifes past. Highlighting a significant shift towards interdisciplinary collaboration, this is a valuable resource for students and researchers interested in the integration of organismal and molecular biology ...

Invertebrate fossil, GSA Cenozoic Toulmin number 5682, from the GSA Cenozoic Toulmin invertebrate paleontology collection. This specimen box contains 9 specimen(s) of the Clam Unidentified Bivalve from the Paleocene Clayton Formation in Wilcox County, AL, USA.
Last week on Fossil Friday, I gave you an entire body (minus the head!) and a simple request: identify this fossil, where it was found, and what the heck a "synapsid" is. There were many valiant attempts, but the best came from Clayton Pilbro:. "Sphenacodon possibly ferox, Permian, known from New Mexico, Arizona, and Utah, North America. Synapsids are a group of animals that are related to mammals and other currently living amniotes. They posses a derived temporal fenestra with a single arch (making a bar of bone behind the eye orbit). Synapsids were the largest terrestrial vertebrates of the Permian.". Sure enough, this Sephanocodon ferox fossil was found right in New Mexico-stellar job Clayton!. From the UC Museum of Paleontology on synapsids:. "The mammals of today are but one branch of the Synapsida, a great vertebrate group with a 300 million year history. Pre-mammalian synapsids-including the famous "finback" Dimetrodon, shown at the top left-dominated the land vertebrate fauna of the ...
For a recent manuscript project I found myself in need of a cranial reconstruction of the strange pinniped Dusignathus santacruzensis. D. santacruzensis was named from the Purisima Formation in 1927 by Remington Kellogg, the father of modern marine mammal paleontology. Research and interviews conducted by F.A Perry have successfully relocated the type locality, which evaded Kellogg and later forays by E.D. Mitchell in the early 1960s. The holotype specimen consists of a few cranium fragments including a partial maxilla bearing a procumbent canine, a squamosal, and a fragment of the vertex of the skull (a term usually relegated to cetaceans, but utilized for odobenids by Demere [1994]), as well as both dentaries. The exploded nature of the cranium is actually fairly literal; interviews by F.A. Perry indicate the collector poked it with a stick and the skull exploded, and only some of the cranium fragments were recovered. The dentaries are thus far the most distinctive element of the taxon; ...
According to the Paleontology report, Minerals have not replicated any part of the soft tissue and the carbonaceous material of the wall is primary [not replaced], preserving the original layering of the wall, its texture, and fabrics. The paper included electron micrographs of some of those fabrics fossilized fibers.2. The study authors described the worm wall as still flexible, as shown by its soft deformation. And just to be clear, they wrote, The body wall of S. cambriensis [fossil worm] comprises a chitin-structural protein composite.2. Fresh-looking material like this soft chitin and its associated proteins should not cause researchers to merely doubt the worm fossils 551 million year-old age assignment, but to utterly reject it. However, unless secularists pay homage to the Geologic Time Scales age designations for characteristic rock layers, their work would almost certainly fail to be accepted as scientific.. The idea that chitin or any unaltered biological material-soft ...

The common paleontology dig scenario offered by movies and TV documentaries involves a group of paleontologists crouching over an exposed skeleton, brushing sand and dust off of it, revealing more and more of an incredible, articulated skeleton. Of course, thats not how it always works. The erosive forces that reveal fossils we study have always been at work, resulting in plenty of fossils being freed from their matrices of sedimentary rocks and reburied. Alton Dooley offers a clear, well-illustrated three part series on the subject of reworked fossils at Paleolab [Parts 2 and 3 ...
I know its been a while since my last post, but last semester was so bad I needed that much time to recuperate. Pathetic, really. Anyway, earlier this year, my mom and I visited the new California Academy of Sciences, which opened early last fall. To say the least, it was absolutely spectacular. Unfortunately, the new CAS has almost nil when it comes to paleontology - sure, theres an unlabeled T. rex skeleton randomly thrown in the mix, and a bunch of artistic renderings of hominids with the date in Ma on one wall, and an elephant bird, but that doesnt really cut it, Im afraid. The old CAS had an entire wing dedicated to fossil organisms, including a really neat mount of Dilophosaurus wetherilli in-situ. That is now probably hidden deep in the basement. Also, Parabalaenoptera baulinensis (which I think is mounted at LACM), which could have made an awesome exhibit, is nowhere to be found ...

The Snowmastodon Project team pulled thousands of fossils out of snowy mud in a matter of months, a herculean task that would not have been as successful without a small army of volunteers, many of whom came from the Denver Museum of Nature & Sciences paleontology program. The program trains interested laypeople in the art of collecting, studying and curating fossils, one of the only programs like it in the world.
