What dinosaur has the longest name?

Micropachycephalosaurus. Its name means “tiny thick-headed lizard”. It was actually one of the smallest dinosaurs and it lived in a pretty tough neighborhood.

It was 50 centimeters (20 inches) in length and 17 centimeters (7 inches) tall. Its fossil was discovered in Asia. Paleontologists haven’t found a complete set of bones yet but judging from the part of the jaw they’ve found it was probably a herbivore (plant-eater). It lived in the Late Cretaceous period, which was about 89 to 65 million years ago. Other dinosaurs that Micropachycephalosaurus might have bumped into, or more likely hid from during that time include Tyrannosaurus Rex and the Velociraptor. The Micropachycephalosaurus would have made a nice snack for either of these meat-eaters.
