The vertebrate fauna from the Upper Cretaceous Naashoibito Member of the Ojo Alamo
Formation (Sandstone), also known as the Alamo Wash local fauna (AWlf), has been the
focus of intense collecting for over 20 years in order to clarify the biostratigraphic
occurrences of taxa within this unit. Previously, some vertebrate taxa from the underlying De-
na-zin Member of the Kirtland Formation, which lies unconformably below the Naashoibito
Member, were mistakenly included in the original definition of the fauna. Therefore, the …

A nearly complete pair of pubes is identified as a new caenagnathid oviraptorosaur,
Ojoraptorsaurus boerei, n. gen., n. sp., based on having a “spoon-shaped” depression on
the anterior dorsal surface of the pubic boot, an elongated anterior process of the pubic boot,
a recessed enclosed pubic fossa, the distal end of the pubic shaft convex anteriorly, and a
sub-trapezoidal pubic peduncle articulation surface. Ojoraptorsaurus boerei is most similar
to ROM 43250 (previously assigned to Chirostenotes pergracilis Gilmore) from the …
