†Paromomys (Paromomyidae)
Paromomys ist eine Primatengattung innerhalb der Familie Paromomyidae, deren 5 Mitglieder ab dem frühen Paläogen (Paläozän) im Danium lebten, das vor ungefähr 66 Millionen Jahren begann und bis vor 61,6 Millionen Jahren andauerte. Viele Überreste wurden in Vereinigte Staaten von Amerika (USA) gefunden.
Paromomys ist der Gattungsname zweier ausgestorbener Primatenarten aus der Familie Paromomyidae (Unterfamilie Paromomyinae), die im mittleren Paläozän in Nordamerika verbreitet waren.
Paromomys depressidens
Das Typusexemplar trägt die Bezeichnung U.S.N.M. no. 9546. Dabei handelt es sich um einen Teil des rechten Oberkiefers mit einem Prämolaren und einem Molaren.

close to the top of a normal magnetic polarity zone interpreted as C28n, but there is no tie point in the section: see Lucas et al. 1997 | firmly correlated with Wagonroad Upper Horizon, which was included in the list of Tomida and Butler 1980; paleomagnetic data strongly support a correlation between the two horizons descriptions of Robison 1986 do not incorporate the collections reported by Tomida and Butler and Tomida 1982 "Oxyclaenus pearcei" is not discussed by Robison 1986 and I assume it is only present at Wagonroad Upper Horizon Haploconus "inopinatus" is not discussed by Robison 1986 and I assume it is only present at Wagonroad Upper Horizon |
Paromomys maturus
Das Typusexemplar hat die Nummer U.S.N.M. no. 9473. Dabei handelt es sich um einen rechten Unterkiefer mit einem Prämolaren (P4) und einem Molaren (M3) sowie vorderen Alveoli .
