†Microsyops (Microsyopidae)
Microsyops ist eine Primatengattung innerhalb der Familie Microsyopidae, deren 10 Mitglieder ab dem frühen Paläogen (Eozän) im Ypresium lebten, das vor ungefähr 56 Millionen Jahren begann und bis vor 47,8 Millionen Jahren andauerte. Viele Überreste wurden in Vereinigte Staaten von Amerika (USA) gefunden.
Microsyops aus der erfolgreichen Familie Microsyopidae (Unterfamilie Mycrosyopinae) lebte vom späten Paläozän bis ins mittlere Eozän in Nordamerika
Microsyops angustidens
Das Typusexemplar mit der Bezeichnung A.M.N.H. No. 15073 ist ein fragmentarischer linker Unterkiefer mit Prämolaren und Molaren, sowie ein Fragment eines rechten Unterkiefers, ebenfalls mit Prämolaren und Molaren. Der Fund stammt aus der Willwood Formation Wyomings und ist zwischen 55,4 und 50,3 Millionen Jahre alt. Er wird am American Museum of Natural History aufbewahrt. Microsyops angustidens war ein baumlebender Allesfresser. Aufgrund von Messungen seiner Backenzähne geht man von einem Körpergewicht von 886,1 Gramm aus.

Microsyops annectens
Das Typusexemplar mit der Bezeichnung Y.P.M. No. 11791 ist ein Unterkieferfragment mit einem Molaren (M3). Microsyops annectens war ein baumlebender Allesfresser. Aus Messungen seiner Backenzähne schließt man auf ein Körpergewicht von 2,49 Kilogramm.

| Ernährung/Lebensraum | |
| Basierend auf den Fossilien glaubt man, dass die Primatengattung Microsyops Allesfresser (omnivor) waren. Ihr Leben verbrachen die Tiere vermutlich in den Bäumen (arboreal), wo sie auch ihre Nahrung fanden. | |

Granger and Olsen also made good collections here." |
