🦕Dinosaurs were mesotherms, with a unique combination of features from both reptiles and birds.
🐊Dinosaurs were not cold-blooded reptiles, but had a higher metabolism and were more active.
🐦Dinosaurs had feathers, which served various purposes such as attracting mates and keeping warm.
📚Previous assumptions about dinosaurs as slow and sluggish have been challenged by new research.
🌍Dinosaurs were diverse and complex creatures that lived in a variety of environments.
What is a mesotherm?
—A mesotherm is an organism that has a metabolism in-between that of cold-blooded reptiles and warm-blooded birds.
Why did dinosaurs have feathers?
—Feathers served various purposes for dinosaurs, including attracting mates, display, and insulation.
