Large Dinosaurs Ran Hot Size does matter -- at least when it comes to dinosaurs' body temperatures, according to new research. Using growth rate and age information gleaned from fossils, researchers have estimated likely body temperatures for dinosaurs of various sizes, as well as tyrannosaur survival rates. |

Vertebrates and tectonics Paleontologists suggested some new twists on tectonics and ecosystems at the annual meeting of the Society of Vertebrate Paleontology (SVP), held mid-October. Their ideas might offer answers to some key conundrums regarding extinction, speciation and the global distribution of vertebrate species. |
