Deltadromeus agilis Sereno, Dutheil, Larochene, Larsson, Lyon, Magwene, Sidor, Varricchio & Wilson, 1996

– This taxon was collected in the Kem Kem region, southeastern Morocco, and was found in the lower layers (Cenomanian) of the Kem Kem beds . The holotype, SGM Din-2, is an incomplete postcranial skeleton that includes at least a cervical rib, anterior dorsal neural arches, two dorsal ribs, two gastralia, four anterior caudal neural spines,eighteen middle to posterior caudal vertebrae, five chevrons, partial scapulocoracoid, humerus, proximal radius, proximal ulna, an impression of part of a left iliac lamina, ischial shaft,fused distal ischia,a right femur, a right proximal tibia, a right distal tibia with the tarsus, a left fibula, left metatarsals II-IV, metatarsal V, and several pedal phalanges.

In the study that described this taxon, Sereno et al. (1996) included a small phylogenetic analysis which placed D. agilis as a coelurosaur. Later, D. agilis was recovered as sister to Ornithomimosauria ( Rauhut, 2000, 2003). Other studies placed this taxon in Ceratosauria ( Carrano & Sampson, 2002; Sereno et al., 2004; Carrano & Sampson, 2008; Pol & Rauhut, 2012). However, after a recent review of E. bambergi , together with other information, D. agilis was assigned to Noasauridae ( Tortosa et al., 2014; Rauhut & Carrano, 2016). Apesteguía et al. (2016), on the other hand, recovered Deltradomeus as a basal carcharodontosaur. Thus, the phylogenetic position of this taxon is still debated.
