Read about research led by former postdoc Katrina Jones, working in the Stephanie Pierce lab and MCZ Vertebrate Paleontology, in the Harvard Gazette. Jones and colleagues looked at the vertebrae of modern reptiles, mammals, and the extinct nonmammalian synapsids to determine how their vertebrae changed over time and how that affected the way these creatures likely moved. The study is published in Current Biology.
