Ourayia is a genus of extinct omomyid primate from the Uinta Formation.
Description
Ourayia had reduced canines and larger incisors when compared to other basal primates, like Notharctus. They also have 1 less premolar than notharctines.[1] Compared to other omomyids from the time, Ourayia is considered large, weighing around 1,500 grams.[2] They had enlarged orbits, like most omomyids.[1] Some authors posit that Ourayia descended from Hemiacodon.[1]
Classification
Historically, species of Ourayia have been assigned to Mytonius and Microsyops,[3] however they were moved to Ourayia by Charles Lewis Gazin in 1958.[1]
