This dataset contains the digitized treatments in Plazi based on the original journal article Gheerbrant, Emmanuel, Teodori, Dominique (2021): An enigmatic specialized new eutherian mammal from the Late Cretaceous of Western Europe (Northern Pyrenees). Comptes Rendus Palevol 20 (13): 207-223, DOI: 10.5852/cr-palevol2021v20a13, URL: doi.org/10.5852/cr-palevol2021v20a13 ABSTRACT We report the discovery of a new Late Cretaceous eutherian mammal, Azilestes ragei n. gen., n. sp. from the Mas-d’Azil northern Pyrenean site (France), which is among the largest known.

It is only known from a broken lower jaw found in uppermost levels of the Grès de Labarre Formation (early Maastrichtian). Despite its poor preservation, it displays distinctive specialized features with respect to known Cretaceous eutherians. This includes a reduced premolar formula and shortened and robust jaw, an incipient hypolophid, and a cingular-like postcristid and hypoconulid.
