The Crocodile is one of the least changed reptiles from the age of dinosaurs. Many crocodiles today have some of the same features as early crocodiles. Crocodiles have evolved over time, but not as much as other animals. The build of crocodiles has changed over time from the start of crocodiles to the later developed too.
Crocodiles have evolved over time, and their shaped and build has changed. First, a crocodiles jaw had been one of the first things that had developed. Next, Crocodiles limbs are different from many; they had started by walking on their hind legs, but later developed the other two and started to walk on all fours. This is why their back legs are longer than the front. Finally, crocodiles had started to swim when they ventured close to water and had long bodies, narrow jaws, and splayed limbs. The shape and build of crocodiles had changed over time. There are many different builds to crocodiles and it had come from many different species.
There were many different species that were similar to a crocodile, and later evolved. First, the Rutiodin had a sleek nose and had a crocodile-like body, but had nostrils on the top of its head. Next, the Mystriosuchus was a 13 foot long animal that had a long narrow snout with many teeth like a crocodile. Finally the Erpetocuchus was about one foot long and only a few pounds, it is also a possibility that it walked on its hind legs. There were many reptiles that resembled a crocodile during this time period. Although there were many early “crocodiles” there were also later reptiles like crocodiles.
There were also many crocodile like creatures that had evolved through later periods. First, the Stromatosuchus was a monstrous dinosaur that was 36 feet long and weighed 10 tons, but what is interesting is it only ate krill and plankton. Second, the Sarsuchus that also developed in this same time period was 40ft long and 10-15 tons, and ate fish and other dinosaurs. Finally, the Dinosuchus that developed later in this period was about 33ft long and 5-10 tons; the skull alone was 6 feet. There were many massive dinosaurs that resembled crocodiles during this time period.
The crocodiles from the later period still resemble earlier ones, but the shape and build has changed. Many things have developed for crocodiles such as the ability to swim over time. The early crocodiles had started out much smaller, and had many features of a crocodile. As time went on, crocodiles had evolved and become much larger, and more “crocodile-like.” Although the crocodile has changed, it is still one of the least evolved animals.
