Crocodiles

No other animal deserves the title of living dinosaur like a crocodile does. These beasts have exhibited the same body form since dinosaurs walked the Earth, surviving the mass extinctions that wiped out nearly all of their mammoth brethren.

In fact, they are the closest living relatives of birds, representing a long-diverged connection between birds and reptiles.
