Grinding Teeth of Duck-bill Dinosaurs More Advanced Than Horses'

A new scientific study shows that duck-billed dinosaurs pulverized tough and abrasive plants with grinding teeth more complex than those of cows, horses, and other well-known modern grazers. The researchers, which included Mark Norell, the chair of the Museum’s Division of Paleontology, are the first to recover material properties from fossilized teeth.

Developmental Timing Offers Another Window Into Dinosaur-Bird Transition

Research posts

A new study has used skull anatomy to show that the evolution of birds from dinosaurs may have resulted from a drastic change in dinosaur development.

In a study published this week in the journal Nature, researchers from Harvard University, the Museum, the New York Institute of Technology, The University of Texas at Austin, and the Autonomous University of Madrid report evidence that while many dinosaurs took years to reach sexual maturity, birds sped up the developmental clock, which led them to retain the physical characteristics of baby dinosaurs.
