Argillomys is an extinct genus of multituberculate mammal that lived in Maryland during the Aptian stage of the Early Cretaceous epoch.[1]
Description
[edit]Argillomys marylandensis, the type and only species, is distinguished by its unique combination of morphological traits on its second molar that include a tooth enamel ornamentation consisting of ribs and grooves only, a cusp formula of 2:4, the presence of a distinct cusp on the anterobuccal ridge, the enlargement of the second cusp of the buccal row, and central position of ultimate cusp in the lingual row.[2]
