The morganucodont Megazostrodon looked like a modern shrew, and may have behaved like one too. It probably hunted for insects and other small invertebrates among the leaf litter and undergrowth, probably during the night, when it was less likely to fall prey to carnivorous dinosaurs.
Its body shape is well known from an almost complete skeleton found in Lesotho, while remains of closely related animals have been found in China and Britain. The skeleton is very similar to that of primitive mammals.
