Life Phyllodon (meaning 'leaf tooth') was a genus of small ornithopod dinosaur from the Kimmeridgian-age Upper Jurassic Guimarota Formation of Leiria, Portugal. It may have been closely related to contemporaneous dinosaurs in North America. This genus is known from teeth and possibly partial lower jaws. The name is also in use for a genus of modern moss, but this is not considered to be a problem because the two organisms are in two different kingdoms. Phyllodon is based on MGSP G5, a partial lower jaw tooth recovered from a lignite marl in a mine near the city of Leiria. Richard Thulborn, who described the genus, added an upper beak tooth (MGSP G2). He regarded the new genus as a hypsilophodontid, and presented a conjectural restoration of the tooth arrangement.
