This ram-sized dinosaur has a big head with a hooked beak and short frill. Unlike its larger cousins, it can walk on just its hind limbs and does not have any horns.

Leptoceratops is a small, slender ceratopsian, smaller even than its more ancient cousin Protoceratops. They are browsers, standing on their hind legs and using their forelimbs to pull branches toward their hooked beaks.

As a small herbivore it was probably hunted by a range of small and medium sized carnivores such as Troodon.

Leptoceratops generally flee if they can, though cornered individuals or aggressive males will charge and head-butt attackers. Will also give a nasty bite.
