Visiting paleontologist Brenda Chinnery, from Johns Hopkins
University, is one of many paleontologists who come to the
Smithsonian every year to examine our specimens. She is measuring
and examining Brachyceratops as part of a study of the
Ceratopsia, or horn-faced dinosaurs, to determine their growth
patterns from juvenile to adult sizes. |
