The Era where Dinosaurs start to dominate

They call it the “age of dinosaurs” for a reason! There were indeed a lot of dinos around during this time. Many carnivorous dinosaurs belonged to the aforementioned group, theropods. These dinosaurs were mostly carnivores, but later in the Jurassic period, some herbivorous theropods evolved, such as the Limusaurus. Excluding modern birds, which are also theropods, the largest theropods were likely the infamous T-Rex which could have been as tall as 13 feet high at the hips and over 40 feet long. They weighed over 16,000 pounds. However, T-Rex did not live until the following Cretaceous period. The smallest ones were the Anchiornis huxleyi which was just a foot long and weight about 100 grams.
