Schoenesmahl is an extinct genus of lizard from the Late Jurassic Painten Formation of Germany.[1] It contains only a single species, S. dyspepsia.[2]
It is known only from specimen SNSB-BSPG AS I 563b, a single disarticulated specimen (consisting of an incomplete skeleton lacking nasals, vomers, palatines, postorbitals, quadrates, anterior presacral vertebrae, pectoral girdles, most of the radii and ulnae, manus, ilium, ischium, tarsals and the distal pedal phalanges form digits I, II, IV and V)
This specimen was long classified in the genus Bavarisaurus,[7] but a 2018 study found it to be a distinct taxon most closely related to Ardeosaurus and reclassified it as its own genus. The status of the specimen as prey for Compsognathus is reflected in the genus and species name, with Schoenesmahl deriving from schöne Mahl (German for "beautiful meal"), while dyspepia (Greek for "difficult digestion") refers to its undigested nature.[2][8]
The well-preserved nature of the specimen suggests that it was eaten by the Compsognathus shortly before the latter's own death and preservation. The disarticulated nature of the specimen suggests that as with some modern predatory birds, Compsognathus may have restrained and dismembered Schoenesmahl during consumption, possibly using its hands and teeth.[2]
