Researchers have used innovative 3D imaging technology called X-ray Reconstruction of Moving Morphology—or XROMM—to develop a way to unlock new insights into how dinosaurs moved. Paleontologists have made great strides in understanding how extinct animals like dinosaurs walked, ran, swam, and flew when they were alive—but much about the mechanics of how different species moved remains uncertain. The current research offers a new perspective on this long-standing conundrum. “By combining the latest technology for studying joint motion with unprecedented amounts of joint pose data, we’ve uncovered surprising new information that will improve reconstructions of locomotion in extinct animals,” says Armita Manafzadeh, a PhD candidate in ecology and evolutionary biology at Brown University and lead author of the paper, published in the
