All are fragmentary mandibles with partial dentition, but only one speci- men, PU 19764, preserves all of P4. In P4 of this specimen, the presumed homo- logues of the molar trigonid cusps are prominent, with both paraconid and meta- conid situated slightly lingual to the proto- conid.

All are fragmentary mandibles with partial dentition, but only one speci- men, PU 19764, preserves all of P4. In P4 of this specimen, the presumed homo- logues of the molar trigonid cusps are prominent, with both paraconid and meta- conid situated slightly lingual to the proto- conid. The fourth, anteriormost cusp is much lower and very small, smaller than in other specimens referred to E. florencae. Whether this feature is significant taxo- nomically is unclear at present; PU 19764 is.
