Taxonomy
Juravenator starki was named by Göhlich and Chiappe (2006). Its type specimen is JME Sch 200, a skeleton, and it is a compression fossil. Its type locality is Stark Quarry, Schamhaupten, which is in a Kimmeridgian lagoonal/restricted shallow subtidal lime mudstone/bindstone in the Painten Formation of Germany.

Diagnosis

|---|---|---|
| L. M. Chiappe and U. B. Göhlich 2010 | Small basal coelurosaur (a clade encompassing Passer domesticus and all taxa sharing a more recent common ancestor with it than with Allosaurus fragilis) with a large skull proportionally longer than in Compsognathus longipes (skull: femur and skull: presacral vertebrae ratios are 1.5 and 0.47, and 1.1 and 0.25 in Juravenator and C. longipes, respectively), low number of maxillary teeth (less than 10 in Juravenator, 10 in Ornitholestes hermanni, 12 in Sinosauropteryx prima, 15 in C. longipes), absence of a premaxillary-maxillary (diastema present in Scipionyx samniticus), distinct indentation on the dentigerous margin of the maxilla (between second and third teeth), an antorbital fenestra subequal in length to orbit (antorbital fenestra is nearly half the orbit in S. prima, Ornitholestes hermanni, and S. samniticus and subequal to the orbit in C. longipesand basal tyrannosauroids [XU et al. 2004, 2006; SERENOet al. 2009]), long scapula (humerus:scapula and scapula:femur ratios are 0.63 and 0.81 in Juravenator, 0.86 and 0.60 in S. prima, and 1 and 0.54 in C. longipes, respectively), of which the narrowest portion is at the neck as opposed to near the mid-shaft, and short feet (metatarsal III: femur is 0.59 in Juravenatorand approximately 0.75 in S. primaand C. longipes[CURRIE& CHEN 2001]). Juravenatoris also unique among other basal coelurosaurs in having longer and more slender teeth, a concave rostral margin of the jugal process of the postorbital, humeri with very short and triangular-shaped deltopectoral crests, manual claws that are very high proximally and that taper abruptly around their midpoints, and arched, bow-like zygapophysial articulations in the mid-caudal vertebrae. We regard these unique features as autapomorphies of Juravenator starki. |
