Minotaurasaurus (Greek for "Minotaur lizard"); pronounced MIN-oh-TORE-ah-SORE-us
Plains of central Asia
Late Cretaceous (80 million years ago)
Size and Weight:
About 12 feet long and half a ton
Large, ornate skull with horns and bumps
A faint whiff of disreputability hangs around Minotaurosaurus, which was announced as a new genus of ankylosaur (armored dinosaur) in 2009. This late Cretaceous plant eater is represented by a spectacular skull, which many paleontologists believe actually belonged to a specimen of another Asian ankylosaur, Saichania. Since we don't know much about how the skulls of ankylosaurs changed as they aged, and hence which fossil specimens belong to which genera, this is a far from uncommon situation in the dinosaur world.
