Emausaurus is a genus of thyreophoran or armored dinosaur from the Early Jurassic. Its fossils have been found in Germany. The type and only species, Emausaurus ernsti, was formalized by Harmut Haubold in 1990.[1] The generic name is composed of an acronym of Ernst Moritz Arndt University of Greifswald and Greek sauros/σαυρος (lizard). The specific name is derived from the name of geologist Werner Ernst, who found the fossil, holotype SGWG 85, in the summer of 1963 at a loampit near Grimmen, in strata dating from the Toarcian.

Description[edit]

The body length of the holotype of Emausaurus has been estimated at around two metres. This represented a juvenile individual though; adult length has been estimated at four metres.[citation needed] It is known from a skull, lower jaws and partial postcranial remains, although only the skull is known well.[clarification needed] Armor includes three conical scutes and one tall, spiny element.[2]

Phylogeny[edit]

Cladistic analyses showed that Emausaurus was a basal member of the Thyreophora, more derived than Scutellosaurus, but less than Scelidosaurus.[citation needed]
