Coloradolops cardonensis
Discussion
The species name cardonensis is because the fossil locality was found at Los Cardones National Park (Salta Province, Argentina)
Taxonomy
Coloradolops cardonensis was named by Chornogubsky et al. (2019). Its type specimen is IBIGEO-P 49a, a partial skull (skull fragment with the roots of the first right and left incisors, right P3–M1, and fragment of M2), and it is a 3D body fossil. Its type locality is Camino de los Colorados road, Quebrada Grande, which is in a Lutetian floodplain siltstone/conglomerate in the Quebrada de los Colorados Formation of Argentina.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| L. Chornogubsky et al. 2019 | Coloradolops differs from other genera of Prepidolopidae (Punadolops alonsoi, Prepidolops spp.) in: larger size; P3 absolutely and relatively larger with a huge lingual root and a larger lingual development of the crown; upper molars with less difference in height between the stylar shelf and the trigon basin, with StB and
D closer to each other, less buccolingual alignment between paracone and StB (i.e. paracone mesiolingually placed with respect to StB) and metacone and StD (i.e. metacone distolingual to StD); and protocone proportionally more robust and with the preprotocrista and the postprotocrista more obliquely oriented (less transverse to the molar row). It is similar to Punadolops but differs from Prepidolops in that the M2 is proportionally longer than the M1. |
