Why were dinosaurs so big??? When you see the bones in the Quarry Exhibit Hall, it is hard not to wonder about their massive size! Dinosaurs were some of the largest animals that ever lived, and there are many theories about why they were so large. Here are some ideas: - Available vegetation. Temperatures and atmospheric conditions fueled lush plant growth, and with more to eat, dinos reached giant sizes. - Self defense. It would have been hard for even large predators to attack a dinosaurs like Dipolocus, who may have been up to 89 feet long and between 10-15 tons. - Body temperature. While there is a complex debate over whether dinos were cold or warm-blooded, one theory is that large sized dinosaurs were cold-blooded and used their large sizes to maintain internal temperatures. It's likely a combination of these theories, and maybe others that have not been developed yet! Further research may provide additional answers to this seemingly simple question. Thanks to @josep_pep for the photo and sense of scale! #dinosaurnps #dinosaurnationalmonument #dinosaurs #giants #scale #science #mystery
