Diagnosis
ReferenceDiagnosis
L. N. Cooper et al. 2009P4 taller than M1; protocone lobe of P4 prominent; M1 labiolingually narrower than P4; small angle be- tween M2 protocone and labial base of trigon; protocone round- ed, slightly bulbous; M3 trigon base mediolaterally wide, steep anterior and posterior borders; p4 taller than m1-m3, anteropos- teriorly elongated at base. Differs from Nalacetus (H-GSP 18521, 96055) and Ichthyolestes (IPHG 1956 II 7) in: protocone rounded, bulbous. Differs from Nalacetus in: M3 trigon labiolin- gually wider base, more lingually oriented paracone tip.
