Dinosaur Teeth Show Which Species Preferred Squishier Prey

What did dinos munch for lunch? A new two-pronged approach to analyzing dinosaur teeth reveals that, while all of the dinosaurs in the study were meat-eaters, when sidling up to The Old Cretaceous Country Buffet some went for the soft-serve prey and others gravitated toward the hard stuff.

Eyes may be the window to the soul, but teeth are the record-keepers of an individual. Earlier this month, a team of researchers determined whether meat or fish was on the menu for assorted apex predators 100 million years ago in the massive river delta systems of what’s now North Africa. That study looked at calcium isotopes preserved within the teeth, but the exterior of a tooth can be just as informative.
