This dinosaur restoration is inaccurate, or its accuracy is disputed.

Reason: Shrink-wrapped, proportions, arm attachment, insufficient feathering on Haplocheirus

Summary[edit]

Description

It is interesting to compare the dentition and arms of these three dinosaurs. Allosaurus, or a T. rex-like dinosaur, had sharp pointy teeth. The Alvarezsaur, Haplocheirus, had many shorter teeth, and the most bird-like dinosaur of the group, Shuvuuia, had reduced peg-like dentition. Also note the three claws of roughly equal size of the Allosaurus, the thick short thumb and two skinny fingers of Haplocheirus, and the completely reduced single digit of Shuvuuia. For more information, see the NSF news release.
