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]
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.
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.

Cretaceous-aged dinosaur fossil localities of Mongolia; Deinocheirus fossils have been collected in the Altan Ula III, IV, and Bugiin Tsav localities of area A (left). The first known fossil remains of Deinocheirus were discovered by Polish palaeontologist Zofia Kielan-Jaworowska on July 9, 1965, at the Altan Ula III site (coordinates) in the Nemegt Basin of the Gobi Desert

The forelimbs were very short, but remained fully functional. The hand had four fingers with claws on the first three. The tail was deep from top to ...

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 ...
As one of the first well-known theropod dinosaurs, it has long attracted attention outside of paleontological circles, and has been a lead dinosaur in several films and documentaries. Allosaurus was a large bipedal predator with a large skull, equipped with dozens of large, sharp teeth. It averaged 8.5 meters (30 ft) in length, though ...
