  • Prominent names in invertebrate paleontology include Steven Stanley, Stephen Jay Gould, David Raup, Geerat Vermeij, and Jack Sepkoski who have done much to expand our understanding of long-term patterns in the evolution of life on earth. (crystalinks.com)
Fossils7
  • Paleontology is the study of ancient life through time by looking at fossils . (nps.gov)
  • Paleontology, which is the science of ancient life and deals with fossils, is mutually interdependent with stratigraphy and with historical geology. (britannica.com)
  • Although vertebrate paleontology has close ties with stratigraphy, vertebrate fossils usually have not been extensively used as index fossils for stratigraphic correlation, vertebrates generally being much larger than invertebrate fossils and consequently rarer. (britannica.com)
  • The primary economic importance of paleontology lies in the use of fossils to determine the age and nature of the rocks that contain them or the layers above or below. (crystalinks.com)
  • The science that carries out research into fossils, their formation and preservation is called palaeontology. (pms-lj.si)
  • Fossils, however, are not just the bones of large dinosaurs, but also the microscopic remains of foraminifera in limestone or pollen in soft clay. (pms-lj.si)
  • The field of palaeontology is currently undergoing a revolution, and our perception on what a fossil is and what can be preserved in the fossil record are fundamentally changing (among other things, it has been shown that residues of the original biological make-up can be retained in fossils many million-of-years old).

  • His new paper in the journal Paleobiology investigates what pollen malformations, or abnormally shaped pollen grains, can tell us about stress in the environment. (phys.org)
  • Previous studies showed that stressors like heightened UV-B radiation exposure and environmental pollution can affect the shape of pollen grains that cone-bearing trees produce and even cause trees to become temporarily sterile. (phys.org)
  • These pollen grains are especially useful for looking at long-term changes in climate because they accumulate in environments conducive to fossilization and are found in many different ages of rock. (phys.org)
  • While at the University of California Berkeley, he and his co-authors Ivo Duijnstee and Cindy Looy sampled pollen grains from 14 different species of conifer from around the world mostly grown in their Botanical Garden. (phys.org)
  • But when they exposed one modern pine species to high levels of UV-B radiation, essentially simulating an ozone weakening event, these plants produced a much higher rate of malformed pollen grains. (phys.org)
  • Most of these conifer plants produce pollen called bisaccate grains, or winged pollen grains. (phys.org)
  • These wings, or sacci, help the pollen grains ride the wind, sometimes hundreds of miles away from the tree that produced it. (phys.org)
  • In this case, a spike in three-winged pollen grains could be an indicator of ozone weakening events. (phys.org)
  • Grains of pollen are so distinctive from one plant species to another (pollen from at least six species is shown in this colorized micrograph) that they can provide powerful evidence in criminal cases. (sciencenews.org)
