Genuine artifacts tell the richest stories that fill our souls. And they fuel the scientific enterprise.

New finds in palaeontology are dependent on people getting out in the field and digging up fossils, but are the next generation of palaeonto

A rostral beak, a highly keratinized tissue covering the perioral region of the skull, has been hypothesized for many sauropodomorphs and eusauropods over the past few decades by several authors, base...

Blood flow rates to long bones of archosaurs reveal high aerobic metabolic rates and endothermy throughout most of their evolutionary history

The nature of the physiology and thermal regulation of the nonavian dinosaurs is the subject of debate. Previously, arguments have been made for both endothermic and ectothermic metabolisms on the basis of differing methodologies. We used clumped isotope thermometry to determine body temperatures fr …

Background One of the great unresolved controversies in paleobiology is whether extinct dinosaurs were endothermic, ectothermic, or some combination thereof, and when endothermy first evolved in the l...
