Megazostrodon (Jurassic)

Megazostrodon is a small, furry mammal with a pointy muzzle and a long tail, very similar to a shrew. This species lived about 225 million years ago, from the Late Triassic to the Early Jurassic. Modern-day mammals probably descended from the Megazostrodon.
Megazostrodon inhabited burrows and was a nocturnally active animal for extra protection from predators. It was only 10 cm in size, possibly becoming a prey to almost anyone. Its food included insects, tiny reptiles, dinosaur eggs and even worms. Megazostrodon was anegg layer, however, it breastfed its cubs instead of abandoning them
This seemingly harmless animal was a ruthless hunter. Thanks to the remarkable variety of, including canines, incisors, premolars, and molars it could easily crush an insect’shard carapace and consume it. Megazostrodon used its powerful limbs to protect itself from predators. Its skeletal joints had a great range of movement, making it very agile and fast.
