Why am I replacing Critter of the Day with this segment? I'm a slacker. The very first Critter of the Week is Deltadromeus agilis, a medium-sized carnivore from the Cretaceous of North Africa. Deltadromeus is a member of a little-known family of ceratosaurs known as the Noasauridae. This family is characterized by their slender builds, which differentiate them from their abelisaurid cousins. Though Deltadromeus' skull has never been found, it is known from a few, relatively complete skeletons. It may have been a swift runner, and certainly would have to have been, to avoid its larger contemporary, Carcharodontosaurus. It was first described by Sereno et. al in 1996, and may be a junior synonym of the mysterious Bahariasaurus.
