 Most caenagnathid species are known from very few remains, and "Ojoraptorsaurus" is no exception.The holotype was compared to well-described pubic remains of other oviraptorosaurians, namely "Microvenator", "Epichirostenotes", "Nomingia", and CM 78001 (now known as "Anzu").It shares with the latter three taxa an enclosed fossa on the inside edge of the pubis near the acetabular rim, a trait which may be diagnostic to caenagnathids (in which case "Nomingia" is a caenagnathid).
