Where are All the Tiny Dinosaurs?

A dinosaur as small as a mouse—pretty hard to imagine, right? That might be because most of the dinosaurs we know and love—T. rex, Apatosaurus, Triceratops—are all huge. Or it could be because tiny dinosaurs simply didn’t exist. 

Join paleontologist Roger Benson at the American Museum of Natural History in New York City to find out about the biggest and smallest known dinosaurs, how paleontologists look for traces of tiny ancient animals, and why the fact that scientists have not yet found a tiny dinosaur fossil remains a big puzzle.
