Minmi

Minmi was a small Ankylosaurid that lived in Australia in the Early Creataceous. It was first described by Ralph Molnar in 1980. Minmi used to hold the title for the dinosaur with the shortest genus name but that title has since fallen to Mei. It is possible that during annual migrations to retreat from the freezing winters at the south pole that Minmi accompanied large herbivores such as Muttaburrasaurus for protection.

Although Minmi was well protected on the top half of its body, there was very little protection on its belly. If an Allosaur could manage to role the creature over then Minmi would be helpless.
