| But
these popular dinosaurs tell only a small part of the story. Paleontologists
have identified over 400 different species of extinct dinosaurs.
To see some strange and unusual dinosaurs you've
never heard of (unless you're a paleontologist), play with the
cladogram .
A cladogram is like a family tree. It's a way of organizing dinosaurs
based on the unique characteristics they share, like a three-toed
foot or a hole in the hip socket.
