Why were dinosaurs so big climate?

dinosaurs had a number of advantages over other animals that lived at the same time. Their relatively large bodies would have allowed them to generate more heat than smaller animals. They would have also been able to access food sources that were either too high or too low for other animals to reach. To keep warm, they could bask in the sun, broad swaths of which would have covered the earth during the day.

Why were dinosaurs so big climate change?

Large animals require a large energy budget, and to acquire enough energy in a tropical climate, large animals need to eat plants that have a high energy density. Plants generate energy in the form of chemical bonds stored in their cells. In order to grow large, plants need lots of carbon dioxide (CO2) to build up their energy-rich tissue. It follows that the more CO2 an animal has available to it while foraging, the more energy it can gain. Dinosaurs were the first animals

Why were dinosaurs so big in the age of the dinosaurs?

Dinosaurs are the top predator of all time, and as such, they had to be large. Life on the plains during the Jurassic and Cretaceous were quite different from life on the coasts. Large prey animals roamed the plains, and the biggest dinosaurs were needed to tackle such animals. Smaller dinosaurs would have been eaten by the larger ones. Larger bodies could absorb more energy from food, so they could grow larger.

Why were dinosaurs so big in the age of dinosaurs?

The Cretaceous Period was an era of incredible diversity in the animal world. Dinosaurs dominated the seas, filling every available niche where they could. The reptilian giants of the time were incredibly successful, and were far more efficient than their predecessors, utilizing a variety of tactics for hunting and escaping their predators.

Why were dinosaurs so big in the age of reptiles?

Dinosaurs weren’t the biggest animals on the earth in the age of reptiles—most species of reptiles were small. The biggest reptiles that existed during the age of dinosaurs were crocodilians, which are still present today. Even so, dinosaurs were much, much bigger than the average reptilian species of the same time period. The average weight of a crocodilian species was about 300 kg, whereas the average weight of a dinosaur was about 11 tons!
