Argentodites coloniensis

Mammalia

Taxonomy
Argentodites coloniensis was named by Kielan-Jaworowska et al. (2007). Its type specimen is MPEF 604, a tooth (nearly complete ?left p4, without roots), and it is a 3D body fossil. Its type locality is Arroyo Mirasol Chico, which is in a Maastrichtian terrestrial horizon in the La Colonia Formation of Argentina. It is the type species of Argentodites.

It was synonymized subjectively with Ferugliotherium windhauseni by Chimento et al. (2015).

Diagnosis
ReferenceDiagnosis
Z. Kielan-Jaworowska et al. 2007The strongly convex anterior margin of the tooth and the normal prismatic enamel with average prism diameter of 3.8 μm suggest affinities of Argentodites coloniensis to Cimolodonta. Shares presence of the normal prismatic enamel with members of the Ptilodontoidea, but differs from Laurasian Cimolodonta (including Ptilodontoidea) in having a relatively long and straight posterior margin, and nearly straight dorsal margin (if placed in presumed life position), both features characteristic of some “plagiaulacidans” (i.e., Paulchoffatiidae, Plagiaulacidae, and Allodontidae). Differs from Laurasian cimolodontans with large p4s in having labial side built as nearly a mirror image of the lingual side. Differs from Paracimexomys (the only member of the Paracimexomys group in which the enamel microstructure is known) in having normal prismatic, rather than gigantoprismatic enamel.
