In Depth

       Mirischia is a genus of compsognathid dinosaur that lived in what is now Brazil during the early Cretaceous.‭ ‬Mirischia means‭ ‘‬wonderful ischia‭’‬,‭ ‬and this dinosaur acquired this name because the two ischia‭ (‬bones of the pelvis‭) ‬show an oval foramen‭ (‬opening‭) ‬in the left bone,‭ ‬and a notch in the same position on the right bone,‭ ‬making the ischia asymmetrical.‭ ‬Mirischia would have been a lightly built but fast and agile predator that was perfectly adapted for hunting smaller animals,‭ ‬be they lizards,‭ ‬primitive mammals,‭ ‬smaller dinosaurs or anything else they could catch.
