Dinosaurs Probably Weren't Cold-Blooded, According to Eggshells

Researchers used clumped isotope paleothermometry to study dinosaur eggs, revealing insights into how dinosaurs evolved from cold-blooded reptiles to warm-blooded birds. The study focused on dinosaurs from cooler climates, showing that some species had body temperatures similar to modern endotherms, suggesting they had some control over their body temperature. This research helps us understand the evolution of endothermy in dinosaurs and their descendants.

Why is it significant that some dinosaurs were found to have body temperatures warmer than their surroundings?

What implications does the research have for understanding the evolution of endothermy in dinosaurs?
