Abstract

A fragmentary sacrum from the Upper Cretaceous of the Haţeg Basin is described here. On the basis of a combination of traits, such as large pleurocoels on the first sacral, a prominent neural platform and completely fused neural spines dorsally, it is referred here to Paraves. Comparison with other non-avian theropod sacra indicates that the sacrum of Ornithodesmus cluniculus from Barremian of the Isle of Wight is the most similar to the Haţeg specimen. The specimen is also compared with the sacrum of birds and pterodactyloid pterosaurs. The size of the bone suggests a total body-length of about 1.2-1.5 meters for the animal.
