The Micropachycephalosaurus (meaning "small thick headed lizard") is a monotypic genus of ornithischian dinosaur. It lived in Shandong Province, China during the Late Cretaceous period (between 70.6 and 68.5 million years ago). The incomplete skeleton of the single specimen was found on a cliff southwest of Laiyang. It was bipedal and herbivorous, and currently has the longest generic name of any dinosaur. Ironically, it was also among the smallest of the dinosaurs, at a little over 1 meter (3.3 feet) long.
