Mirischia was a small, speedy meat-eater that lived in what is now Brazil. It had a very unusual pelvis, with the left and right hip bones shaped differently. This dinosaur was about as long as a small car and probably hunted lizards and other tiny animals.1 2

Mirischia had a strange pelvis: the left ischium (hip bone) had a hole, while the right one had an open notch instead. This is why it was named 'asymmetrica'.1

Scientists found a piece of petrified intestine inside the Mirischia fossil. That is very rare for a dinosaur.1 2

The fossil also preserved a space between its pubic and ischial bones that scientists think was an air sac, like the ones birds have today.1

Mirischia lived about 108 million years ago, during the Early Cretaceous, in a hot, dry environment near a lagoon.1 2

Only one Mirischia fossil has ever been found. It was a subadult, so it was still growing when it died.1 2

Mirischia is a compsognathid, meaning it was a relative of the tiny European dinosaur Compsognathus.2
