Imagine a crocodile built like a greyhound—that's a sebecid. Standing tall, with some species reaching 20 feet in length, they dominated South American landscapes after the extinction of dinosaurs until about 11 million years ago. Or at least, that's what paleontologists thought, until they began finding strange, fossilized teeth in the Caribbean. "The first question that we had when these teeth were found in the Dominican Republic and on other islands in the Caribbean was: What are they?" said Jonathan Bloch, curator of vertebrate paleontology at the Florida Museum of Natural History.

A speculative evolution version of Godzilla, one that stays true to the original but with clear sebecid influence.

The dorsal plates are meant to mimic coral as it hunts in the sea.

A Dentaneosuchus crassiproratus, the newly described Sebecid crocodylomorph hailing from the Middle Eocene Sables du Castrais Formation of Southern France 41-37 million years ago, strolls along a riverbank with the head of a Lophiodon crushed in its jaws. D.crassiprotatus had a large skull with powerful jaws that was nearly a meter in length, and the animal itself could also reach a length of up to 5 meters long, making it one of the largest sebecids alongside the South American Barinasuchus as well as possibly Europe’s largest terrestrial predator during the Eocene. So even after the extinction of the dinosaurs, it seems that European mammals would still have to somehow live under the shadow of large sauropsids such as Dentaneosuchus and other crocodylomorphs as well as giant birds such as the herbivorous bird Gastonis.

The Valley of the Gwangi is a wonderfully old movie about dinosaurs and cowboys that would seem inaccurate if not due to the fact that with speculative evolution, you could argue that all the residents of the Valley are just 30 million years of adaptation from sebecid crocodiliyforms in the ways of the retorsaurs created by @tyrantisterror
