New Paper: Reanalysis Shows Dinosaurs Not So Warm-Blooded

From the UCD press release: In 2022, a team led by Yale University researchers used traces of biomolecules from fossils to measure metabolism in animals that died millions of years ago. Their data showed, they claimed, that endothermy evolved even before dinosaurs appeared, in the common ancestor of both dinosaurs and the flying reptiles, pterosaurs. Now a new analysis of the data by paleontologists from UC Davis challenges this interpretation. The study is published Sept. 6 in Nature.” A great collaboration from the whole paleo team at UC Davis–myself, Dr. Motani, Dr. Carlson, and Dr. Vermeij!

New Paper: Will shells survive an age of climate change?

Many marine animals build their shells and skeletons out of calcium carbonate. When ocean water becomes more acidic–as happens when the climate warms–calcium carbonate should be harder to extract. This has many scientists worries about the fate of corals, molluscs, and other important marine life. Indeed, many studies have shown that certain species have trouble building their shells when their water is more acidic, but many other studies do not. What could explain this variation? Dr. Gold explores this question with Geerat Vermeij in a new paper, “Deep resilience: An evolutionary perspective on calcification in an age of ocean acidification.” It is available for free at Frontiers in Physiology.
