This giant snake wants to challenge the mighty Tyrannosaurus rex for the title of Late Cretaceous apex predator. Personally, my money is on the dinosaur, but you have to admire the serpent’s gumption here.
The snake isn’t based on any particular fossil taxon, but I wouldn’t be too surprised if something like it were to be found in Mesozoic sediments someday. We already know some crocodiles and their relatives, such as Deinosuchus and Sarcosuchus, grew big enough to prey on dinosaurs. Why not snakes as well?
