For the novel, Crichton invented the dinosaur's ability to spit venom (explaining how it was able to kill prey, in spite of its seemingly weak jaws). The art department added another feature, a neck frill or cowl folded against its neck that expanded and vibrated as the animal prepared to attack, similar to that of the frill-necked lizard.
Frill-necked lizard showing its neck frills Skull of Triceratops with its large neck frill. A neck frill is the relatively extensive margin seen on the back of the heads of reptiles with either a bony support such as those present on the skulls of dinosaurs of the suborder Marginocephalia or a cartilaginous one as in the frill-necked lizard.
Triceratops (/ t r aɪ ˈ s ɛr ə t ɒ p s / try-SERR-ə-tops; [1] lit. ' three-horned face ') is a genus of chasmosaurine ceratopsian dinosaur that lived during the late Maastrichtian age of the Late Cretaceous period, about 68 to 66 million years ago in what is now western North America.
The neck of T. rex formed a natural S-shaped curve like that of other theropods. Compared to these, it was exceptionally short, deep and muscular to support the massive head. The second vertebra, the axis, was especially short. The remaining neck vertebrae were weakly opisthocoelous, i.e. with a convex front of the vertebral body and a concave ...
Diplodocoidea is a superfamily of sauropod dinosaurs, which included some of the longest animals of all time, including slender giants like Supersaurus, Diplodocus, Apatosaurus, and Amphicoelias. Most had very long necks and long, whip-like tails; however, one family (the dicraeosaurids ) are the only known sauropods to have re-evolved a short ...
With a neck that is 15 metres long, Mamenchisaurus sinocanadorum might be a record-holder, researchers said. Scientists identify dinosaur with the longest neck ever seen in an animal Skip to main ...
Theropod dinosaur Irritator shown feeding on a pterosaur Pterosaurs are known to have been eaten by theropods . In the 1 July 2004 edition of Nature , paleontologist Éric Buffetaut discusses an Early Cretaceous fossil of three cervical vertebrae of a pterosaur with the broken tooth of a spinosaur , most likely Irritator , embedded in it.
A darkened soft-tissue structure was also found near the jugal horn; this may represent a keratinous sheath or a skin flap. [59] A 2021 study of SMF R 4970 examined its cloaca, the first one known from a non-avian dinosaur. The positioning of the individual when it died is oriented obliquely, so the structure can be seen better in the right side.
