How is looking for mammals different from looking for dinosaurs?
Dinosaur bones are typically large and visible to the naked eye from a distance; dinosaur paleontologists can walk around and spot bones far away exposed on the surface. I spend most of my time crawling around. Mammals during the Mesozoic were small animals; their bones were delicate and are much less easily fossilized. Actually, most early mammal material tends to come from teeth, which are pretty hard. The largest of the Mesozoic mammals were about the size of a raccoon. The teeth of these mammals are usually between half a millimeter to five millimeters long. Keep in mind the width of a dime is one millimeter.
