Dinosaurs were not the only giants of their day. There were colossal crocodiles that were large enough to eat dinosaurs for breakfast. Among these giants were Deinosuchus, Kaprosuchus, and Sarcosuchus. All three of these large crocodilians were the terrors of the prehistoric lakes and rivers. Even Tyrannosaurus Rex feared these crocodiles. I am thinking of including a reverse engineered species of giant crocodile that is of the same caliber as these prehistoric behemoths. Unlike the dinosaurs in the experiment, this crocodile will have been bred behind the research team’s back. Because of this, these crocs will become an unexpected and terrifying surprise for the survivors as they try to escape their manmade ecosystem.
