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.
At 40 centimetres (16 in) long, the skull of Lishulong is larger than any other sauropodomorph from the Lufeng Formation. The cervical vertebrae are very large and elongated; the centrum of the first preserved cervical vertebra (the axis) is 16.3 centimetres (6.4 in) long, and the centrum of the last preserved cervical vertebra (the tenth consecutive bone in the series) is 19.9 centimetres (7. ...
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.
Jaw and teeth of Lanzhousaurus. The genus has been described as having "astonishingly huge teeth", among the largest for any herbivorous creature ever, which indicate it was a styracosternan iguanodont. The mandible, longer than one meter, suggests a very large size for the animal. Tooth enamel of this dinosaur was growing very rapidly. [3]
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.
The Komodo dragon has a tail as long as its body, as well as about 60 frequently replaced, serrated teeth that can measure up to 2.5 cm (1 in) in length. Its saliva is frequently blood-tinged because its teeth are almost completely covered by gingival tissue that is naturally lacerated during feeding. [ 29 ]
The actual material comprising a dinosaur tooth is not very different to teeth in modern animals. Most significant differences are in how the teeth fit together and continually regrew, with some examples shedding old teeth and others reabsorbing old teeth as they would grind down under chewing throughout a dinosaurs life.
Dinosaur remains that were discovered in China have been described as one of the "saddest fossils." As Seeker reports, the creature, called Mud Dragon, was found with its neck and wings extended ...
