"In 1941 Richard Owen said that the dinosaurs were almost hot blooded"

In 1941, paleontologist Richard Owen proposed that dinosaurs were "nearly hot-blooded" animals, suggesting that they had a higher metabolic rate than other reptiles. This was an innovative idea at the time, as it was widely believed that dinosaurs were sluggish, cold-blooded animals. Owen's hypothesis was based on the observation that dinosaurs were much bigger than other reptiles, and that they had a more active way of life. He argued that their bigger size and increased activity levels might only be sustained by a higher metabolic rate. Owen's hypothesis was later on supported by the discovery of dinosaur fossils with evidence of rapid development, suggesting that they had a greater metabolic rate than other reptiles. This idea has considering that been accepted by the clinical community, and it has actually assisted to shape our understanding of dinosaurs as active, dynamic animals.
