Complete Primate Skeleton from the Middle Eocene of Messel in Germany: Morphology and Paleobiology

Figure 5

Map of deciduous and permanent teeth of the right side in the skull of Darwinius masillae, new genus and species.

Deciduous dI2 has not yet been shed, and dC1/dC1, dP3/dP3, and dP4/dP4 are still functional. Permanent teeth that are fully erupted include I1/I1, P2/P2, and M1/M1 (P2 is present on plate B [1). Erupting teeth include I2/I2 and M2/M2. Crowns of M3/M3 are fully formed but lack roots. Crowns of P3/P3 and P4/P4 are partially formed, with P4/P4 notably more developed than P3/P3. The crown of C1 appears to be fully formed, while that of C1 is less mineralized. Judging from the stage of crown formation, premolars erupted in the sequence P2/P2 – P4/P4 – P3/P3, as in Cantius (Gingerich and Smith, in prep.), Notharctus [23, pl. LII: 9], and Europolemur [16, pl.III: 3].
