Mirischia asymmetrica Naish et al., 2004 |

Mirischia is a small (two meter-long) extinct genus of compsognathid theropod dinosaur from the Albian stage (Early Cretaceous period) of Brazil.
In 2000 David Martill and Eberhard Frey reported the find of a small dinosaur fossil present in a chalk nodule, illegally acquired by the German Staatliches Museum für Naturkunde Karlsruhe from an illegal Brazilian fossil dealer who had indicated the piece had been uncovered in the Chapada do Araripe, specifically at Araripina, Pernambuco. In 2004 the type species Mirischia asymmetrica was named and described by Martill, Frey and Darren Naish. The generic name combines the Latin mirus, 'wonderful', with "ischia", the Latinised plural of Greek ἴσχιον, ischion, 'hip joint'. The specific name asymmetrica refers to the fact that in the specimen the left ischium differs from its right counterpart.
The holotype, SMNK 2349 PAL, has its probable provenance in the Romualdo Member of the Santana Formation, dating from the Albian. It consists of a partial articulated skeleton, largely consisting of the pelvis and incomplete hind limbs, including two posterior dorsal vertebrae, a rib, gastralia, partial ilia, pubes and ischia, partial thigh bones and the upper parts of the right tibia and fibula. In front of the pubes, a piece of a petrified intestine is present. The specimen represents a subadult individual.
