The findings may help us understand how carnivorous dinosaurs, which had curved, serrated teeth similar to Komodo dragons, would have killed and eaten their prey, LeBlanc said.
Like all sauropods, Nigersaurus was a quadruped with a small head, thick hind legs, and a prominent tail. Among that clade, Nigersaurus was fairly small, with a body length of only 9 m (30 ft) and a femur reaching only 1 m (3 ft 3 in); it may have weighed around 1.9–4 t (2.1–4.4 short tons), comparable to a modern elephant.
However, at least one pterosaur did have both the Pteranodon-like crest and teeth: Ludodactylus, whose name means "toy finger" for its resemblance to old, inaccurate children's toys. [211] Pterosaurs have sometimes been incorrectly identified as (the ancestors of) birds, though birds are theropod dinosaurs and not descendants of pterosaurs.
Pteranodon (/ t ə ˈ r æ n ə d ɒ n /; from Ancient Greek: πτερόν, romanized: pteron ' wing ' and ἀνόδων, anodon ' toothless ') [2] [better source needed] is a genus of pterosaur that included some of the largest known flying reptiles, with P. longiceps having a wingspan of over 6 m (20 ft).
Reisz also examined the gums, teeth and lips of modern-day dinosaur relatives like crocodiles and monitors. Crocodiles have more exposed teeth, while monitors have a set of scaled lips.
Some of the most important anatomical information about dinosaur teeth is collected from polished, microscopically thin sections , including the types of dental tissues present, tooth wear, tooth replacement patterns, how the teeth are attached, and the frequency of replacement. The actual material comprising a dinosaur tooth is not very ...
Dimorphodon (/ d aɪ ˈ m ɔːr f ə d ɒ n / dy-MOR-fə-don) was a genus of medium-sized pterosaur from Europe during the early Jurassic Period (about 201-191 million years ago). [1] It was named by paleontologist Richard Owen in 1859.
Originally, this genus was believed to be a prosauropod because of the knife-shaped teeth found near its fossils, which fit in with the idea that prosauropods were omnivorous. Scientists now know that the teeth belonged to an unidentified theropod that may have scavenged on the Vulcanodon carcass. Vulcanodon is now known to be a true sauropod.
