Bavarisaurus

Bavarisaurus ('Bavarian lizard') is an extinct genus of basal lizard found in the Solnhofen limestone near Bavaria, Germany. A fossil skeleton found in the stomach region of a "Compsognathus", a small theropod dinosaur, was originally assigned to the genus, but was renamed to "Schoenesmahl" in 2017.
The holotype is BSPHM 1873 III. Part of the holotype is now lost.
