Description

Some carnivores eat only meat, while others are more omnivorous. To understand how and when these differences in carnivore feeding may have evolved, Museum paleontologists captured X-ray scans of skulls from living and extinct species. They reconstructed the skulls as virtual models and designed feeding simulations, to test the relationship between skull biomechanics and diet, shedding light on the evolution of feeding specializations and their distribution in the carnivore family tree.

Science Bulletins is a production of the National Center for Science Literacy, Education, and Technology (NCSLET), part of the Department of Education at the American Museum of Natural History.
