Spinohagosaurus

Spinohagosaurus (name meaning spine sided lizard), formerlly known as Kentrosaurus Americanum, is an extinct genus of stegosaurian dinosaur from the Late Jurassic of what is now North America. It was once thought to be a species of Kentrosaurus due to its similarities, but further analysis showed that its spine sticking out of its sides pointed out more than Kentrosaurus, giving it a new genus, Spinohagosaurus.
