Physical appearance and biologyEdit
Proterosuchus was a large archosaur that resembled crocodilians like gharials. It had slim jaws lined with sharp teeth. It had long legs in comparison to modern crocs and lacked the rough scales. It had a striped and relatively flat tail.
Proterosuchus was light green with a white underbelly and dark green stripes on the tail.
Behaviour and traitsEdit
Proterosuchus was an amphibious archosaur. It closely resembled modern day crocodilians such as the gharial. Like crocodiles, they mainly lived in water and sometimes came onto the bank to bask. Unlike most crocodiles, Proterosuchus was a social animal.The jaws of Proterosuchus were strong and were lined with sharp teeth used to grip onto prey. At the tip of the top jaw was a curvature. This curvature had slightly long and sharper teeth. This adaptation helped this creature to clamp onto prey without it straying away.
Proterosuchus also had rather long legs compared to other crocodilians or crocodilian-esque creature. However, these legs were not used for chasing. They were rather used for easier mobility on land and for better swimming abilities under water.
During the seasonal Lystrosaurus migrations, Proterosuchus served as a major threat to the herd as well as the water. When a Lystrosaurus herd had to cross a river, the resident archosaurs would take advantage of the situation and would attack as many animals as possible. With its power and the conditions, the attacks performed were often fatal. The Proterosuchus would feed on the festering corpses after the remaining Lystrosaurus had left.
At a river bank, a group of Proterosuchus were basking with their jaws wide open. A Euparkeria approached one of the archosaurs which had a dragonfly resting in its jaws. As the reptile approached the resting chasmatosaur, the dragonfly flew away and the Proterosuchus snapped its jaws at the Euparkeria but it fled. The chasmatosaur then chased its prey.
The group of Proterosuchus then returned to the water as the Lystrosaurus herd approached the river to cross it.
As lots of Lystrosaurus began to cross the river, the Proterosuchus began to massacre them. After the remaining Lystrosaurus reached the opposite side of the river, the chasmatosaurs began to feast on the floating corpses.
Later, as a Euparkeria began to feed on a corpse, it evolved into an Allosaurus in front of a cowering Proterosuchus.
