How do they know where to dig for dinosaurs?

Congratulations—you’ve found dinosaur bone fragments! Now you have to find out where they come from. Paleontologists call these small bone fragments “float” and they map the float to determine the most likely source and where to dig. Float mapping is a study in erosion and taphonomy (decay).

Can dinosaurs come back?
