What kind of animal is Deinonychus?
Deinonychus (/daɪˈnɒnɪkəs/ dy-NON-i-kəs; from Greek: δεινός deinós, ’terrible’ and ὄνυξ ónux, genitive ὄνυχος ónuchos ’claw’) is a genus of carnivorous dromaeosaurid coelurosaurian theropod dinosaur with one described species, Deinonychus antirrhopus.
Did Deinonychus live and Hunt in packs?
The association of this number of Deinonychus skeletons in a single quarry suggests that Deinonychus may have fed on that animal, and perhaps hunted it. Ostrom and Maxwell have even used this information to speculate that Deinonychus might have lived and hunted in packs.
Could a Deinonychus kill a tenontosaur?
Brinkman et al. (1998) point out that Deinonychus had an adult mass of 70–100 kilograms, whereas adult tenontosaurs were 1–4 metric tons. A solitary Deinonychus could not kill an adult tenontosaur, suggesting that pack hunting is possible.
Who discovered Deinonychus?
In that same year, another specimen of Deinonychus, MCZ 4371, was discovered and excavated in Montana by Steven Orzack during a Harvard University expedition headed by Farish Jenkins. This discovery added several new elements: well preserved femora, pubes, a sacrum, and better ilia, as well as elements of the pes and metatarsus.
