The Spinogator (scientific name is Altispinosuchus, meaning Tall-Spined Crocodile) is kind of based on Kaprosuchus, but with a sail like a Dimetrodon or an Arizonasaurus. I forgot that the Primordial World was supposed to be a fantasy world, so I decided to make a more bizarre-looking creature design than usual.
They are slightly larger than Kaprosuchus, which is the animal I based the body on
