Dentition
In 1995, two isolated upper molars belonging to E. klatti (pictured in figure 1 under external link 1) were found in an old lake deposit during excavations done by the "Naturhistorisches Museum Mainz/Landessammlung fur Naturkunde Rheinland-Pfalz". The museum determined that the molars (as well as a mandible with nearly complete dentition belonging to another cercamoiines, Periconodon) were representative of the first primates from the Middle Eocene Eckfeld maar in Southwest Eifel, Germany ^2. E. klatti has a dental formula of 2:1:3:3 (Franzen, 1987; cited in Martin, 1990) and the milk dentition of this species consisted of four premolars while the adults only had three premolars. One of the most distinguishing characteristics of the genus Europolemur is the lack of a metaconule. The dental anatomy of their genus is described in more detail by Franzen as consisting of "upper canines big and pointed; upper molars without postflexus; postprotocrista prominent; no metaconulus; M3 smaller and shorter than M2; P4 much shorter than broad, with a weak parastyle; P4 with a small and unicuspid talonid and a metaconid present to absent; protocristid of M nearly transversely oriented. Protoconid of P3 little higher than that of P4." ^2
