Why did dinosaurs get so big?

Dinosaurs lived during the Triassic, Jurassic and Cretaceous. During these periods, the climate was much warmer, with CO₂ levels over four times higher than today. This produced abundant plant life, and herbivorous dinosaurs may have evolved large bodies partly because there was enough food to support them.

How did dinosaurs look after their babies?

What is the story of the 9ft tall human skeleton?

But stranger still, was the discovery of 9ft tall humanoid skeletons. The story was first officially reported in a San Diego newspaper in 1947. The remains were mummified, and were estimated to be around 80,000 years old. However, the story quickly faded away, along with the giant’s remains.

Is Saurophaganax maximus a large theropod?
