, a weathered skull with articulated mandible and associated partial postcranial skeleton. The outer surfaces of the skull and skeleton are highly weathered, and the postcranial skeleton is fragmentary. The skull is missing the dorsal and lateral walls of the braincase and the occiput dorsal to the foramen magnum, and most of the frontals were eroded away (fig. 3). The lower temporal and posttemporal bars are missing on both sides except for a suborbital section of the jugal on the right. The head of the right quadrate is preserved but not the left, and the upper temporal bars are missing on both sides. The illustration of the right side of the skull by

; fig. 4) combines some aspects of the left: the interfenestral bar is preserved only on the left side, but is illustrated on the right side. Both dentaries are preserved but are eroded ventrally. Only the anterior parts of the postdentary bones are preserved on both sides. The preserved postcranial elements include four dorsal vertebrae, six sacral vertebrae, the first four caudal vertebrae, a partial left ilium, parts of both pubes, parts of both ischia, the proximal part of the left femur, the impression of the left tibia, and the distal end of the left pes. Most of these bones were preserved in a concretion, with which a few isolated bones were associated. Many of the elements were removed from the concretion after Osborn’s description. A cast of the pelvic region in the concretion was made before the specimens were removed and is figured here (fig. 5). An isolated series of three caudals originally was referred to the
