In 1970, Rozhdestvensky re-examined the claws and suggested a possible function specialized in opening termite mounds or a frugivore diet. [2] Barsbold in 1976 suggested that the unusual claws of Therizinosaurus may have been employed to impale or dig up loose terrain, however, he pointed out their notorious fragility upon impact. [4]
Iguanodon (/ ɪ ˈ ɡ w ɑː n ə d ɒ n / i-GWAH-nə-don; meaning 'iguana-tooth'), named in 1825, is a genus of iguanodontian dinosaur.While many species found worldwide have been classified in the genus Iguanodon, dating from the Late Jurassic to Early Cretaceous, taxonomic revision in the early 21st century has defined Iguanodon to be based on one well-substantiated species: I ...
Deinonychus (/ d aɪ ˈ n ɒ n ɪ k ə s / [1] dy-NON-ih-kəs; from Ancient Greek δεινός (deinós) ' terrible ' and ὄνυξ (ónux), genitive ὄνυχος (ónukhos) ' claw ') is a genus of dromaeosaurid theropod dinosaur with one described species, Deinonychus antirrhopus.
Plateosaurus was a bipedal herbivore with a small skull on a long, flexible neck, sharp but plump plant-crushing teeth, powerful hind limbs, short but muscular arms and grasping hands with large claws on three fingers, possibly used for defence and feeding.
The teeth became shorter, narrower, and more curved toward the back of the skull. All of the teeth had saw-like edges. They were shed easily, and were replaced continually, making them common fossils. [17] Its skull was light, robust and equipped with dozens of sharp, serrated teeth. The skull had a pair of horns above and in front of the eyes.
Deinonychosauria is a clade of paravian dinosaurs which lived from the Late Jurassic to the Late Cretaceous periods. Fossils have been found across the globe in North America, Europe, Africa, Asia, South America, and Antarctica, [2] with fossilized teeth giving credence to the possibility that they inhabited Australia as well.

A fair portion of modern research has concentrated on the feeding-patterns of these dinosaurs, as they are considered to be the best regarded theropod candidates for herbivory. While other theropod groups are fully carnivorous, members of Therizinosauridae diverged and adopted an herbivorous and possibly omnivorous lifestyle. This is even more ...
Stegosaurus and related genera were herbivores. However, their teeth and jaws are very different from those of other herbivorous ornithischian dinosaurs, suggesting a different feeding strategy that is not yet well understood. The other ornithischians possessed teeth capable of grinding plant material and a jaw structure capable of movements in ...
