[D] Mirischia asymmetrica [sG] [T]
Describer
Naish, Martill, Frey, 2004
Time
Cretaceous Early ?Albian
Classification
Saurischia Theropoda Tetanurae Coelurosauria Compsognathidae
Diet
Carnivore
Fossilsite
Santana Formation, Romualdo Member, Brazil
Length
2.1 meter
Info
Genus - Typespecies
Mirischia is more similar to the European Compsognathus than to the Asian Sinosauropteryx.
Holotype
(SMNK 2349 PAL known for several years as the undescribed Santana Formation compsognathid) (subadult) posterior twelfth dorsal vertebra, thirteenth dorsal vertebra (26 mm), thefth dorsal rib, gastralia, first sacral vertebra, second sacral vertebra, anterior third sacral vertebra, partial ilia, pubes, ischia, incomplete femora (165 mm), proximal tibia, proximal fibula, intestine, postpubic airsac(?)
Diagnosis
(after Naish et al., 2004) pubic peduncle of ilium with concave cranial surface; pubic boot with no cranial expansion and 32% total length of pubis; pedicular fossae located craniodorsal to neural canal on caudal dorsal vertebra; distal tips of the neural spines between 63% and 67% longer than their bases; ventral surface of sacral centra bearing shallow median depressions at either end; extremely thin bone walls to all known elements.
The genusname meaning \\\'wonderful pelvis\\\', the species name comes from the fact that the two hips differ in prominent details. The find was only one of two dinosaurs in the world to be found with preserved guts, and the only confirmed preserved air sac.
