[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).

[4] Othniel Charles Marsh, who examined the specimen in 1881, thought that this small skeleton in the Compsognathus belly was an embryo, but in 1903, Franz Nopcsa concluded that it was a lizard.

[5] In 1978, John Ostrom identified the remains as belonging to a lizard of the genus Bavarisaurus,[6] which he concluded was a fast and agile runner owing to its long tail and limb proportions.

[2] 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.

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.
