Also known as crocodile imposters @Palaeontologica

If the background is familiar its because its a serina based one, which I like

Eleganosuchus emperiosus (elegant emperor crocodile) is a taxon of large, 4 to 5 metre long phytosaurs that lived in the Late Triassic, in what is now the Chinle Formation. Specimens have been found in the Sonsela, Petrified Forest, Blue Mesa and Mesa Redondo areas of the Chinle Formation. It is considered a generalist phytosaur, much like the false gharial (Tomistoma schlegelii), due to its somewhat "in-between" dolichorostral (slim jaws with homodont teeth) and brachyostral (thicker jaws with heterodont teeth), and it has a dorichostral-like jaw, heterodont (teeth size varies) dentition, and a large 'crest' on the head, earning it the type dolibrachyostral jaws. Eleganosuchus teeth have been found in other crocodilians, such as a Vancleavea vertebra found from Blue Mesa in the Chinle Formation, suggesting it fed on other archosauromorphs, fish and synapsids. Eleganosuchus is placed in the tribe Mystriosuchini, which is well known for the most highly divergent phytosaurs, like the terrestrial Nicrosaurus and the fully aquatic Mystriosuchus. Oxygen isotope ratios were found in one exceptionally well-preserved specimen (MNHM 5549) were the same as false gharial's isotope ratios.
