Dino Discovery Solves Puzzle
November 10, 2011
A comparison of the dentition and arms of three dinosaurs: Allosaurus, 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. Note the three, roughly equal-sized claws of the Allosaurus; the thick, short thumb and two skinny fingers of Haplocheirus; and the completely reduced, single digit of Shuvuuia.
