  • ultrasound
  • I also looked on line and read tons of posts from parents that went through this and they said they were told the same thing that throughout their pregnancy, their child had no nasal bone on ultrasound and they came out perfect. (whattoexpect.com)
  • The difficulty is when the gestation is 11 weeks or the beginning of the 12th week and the nasal bone is absent but the NT, the other ultrasound markers and the serum biochemistry are normal. (fetalmedicine.com)
  • NEW ORLEANS -- First-trimester nasal bone evaluation by ultrasound appears to be nearly useless in identifying aneuploidy, with a sensitivity of only 9%, Dr. (thefreedictionary.com)
  • bony
  • The tail of Ceratosaurus was characterized by comparatively high neural spines (upwards directed bony processes of the caudal vertebrae) and elongated chevrons (bones located below the tail vertebrae), giving the tail a deep profile in lateral view. (wikipedia.org)
  • parietal
  • The holotype consists of a right parietal bone. (wikipedia.org)
  • The describing authors indicated two unique traits, or autapomorphies: On the rear rim of the neck frill, the second and third epiparietals, which are skin ossifications attached to the rim, have a wide base, are vertically thick and curve obliquely upwards to the front, overhanging the rear and outer side branches of the parietal bone. (wikipedia.org)
  • The rear of the frill consisted of the rounded parietal bones. (wikipedia.org)
  • midline
  • these bones are fused with the surrounding bones, and simply do not join up in the midline, as they do in other bats. (wikipedia.org)
  • These openings were separated by a broad bone bar which featured a midline ridge that was rather smooth, not adorned by bumps. (wikipedia.org)
  • Uniquely among theropods, Ceratosaurus possessed small, elongated and irregularly formed osteoderms (skin bones) along the midline of its back. (wikipedia.org)
  • vertebrae
  • A partial pelvis (ilium and pubic bone) and two partial dorsal vertebrae from a juvenile individual (specimen ML 433-A) were found at the same location, intermingled with the bones of the holotype, and were also assigned, as a paratype, to M. longicollum. (wikipedia.org)
  • tyrannosaurid
  • New evidence may help explain the brute strength of the tyrannosaurid, says a University of Alberta researcher whose finding demonstrates how a fused nasal bone helped turn the animal into a "zoological superweapon. (eurekalert.org)
  • Snively's team found that fused tyrannosaurid nasals were stronger than unfused carnosaur nasals. (eurekalert.org)
  • In addition to the Wendiceratops bones, remains were found of tyrannosaurid theropods, crocodiles, gars and plants. (wikipedia.org)
  • anterior
  • During embryological development, the vomeronasal sensory neurons form from the nasal (olfactory) placode, at the anterior edge of the neural plate (cranial nerve zero). (wikipedia.org)
  • holotype
  • Casts were made of the holotype bones and partially based on these a life-size skeletal model was constructed from polyurethane and polyester resin parts. (wikipedia.org)
  • The original holotype of D. gracilis is considered a juvenile, however the size of a nothosaur when its bones harden is used to show size, making the estimate as smallest member of its family still valid. (wikipedia.org)
  • Both specimen came from subadult individuals, the referred being more mature than the holotype, as evident by the absence or degree of fusion in some compound bones, such as the carpometacarpus, tibiotarsus and tarsometatarsus. (wikipedia.org)
  • teeth
  • Tyrannosaurids differ from other dinosaurs in the great robustness of their teeth and skulls, enlarged areas for attachment and expansion of jaw muscles and the consequent ability to bite deeply in the bone. (eurekalert.org)
  • outer
  • Each nasal bone has two surfaces: the outer and the inner. (healthline.com)
  • The outer surface of the nasal bone, which is covered by the compressor naris and the procerus muscles, is convex (it curves outward) from one side to the other and concavo-convex (curves in on one side and out on the other, like a contact lens) from the top to bottom. (healthline.com)
