Subgroups

Maniraptoromorpha is a clade of coelurosaurian theropod dinosaurs that includes the taxa Ornitholestes, Coelurus, and Maniraptoriformes.[1] There has been several phylogenetic analyses that have shown support in the grouping of Maniraptoriformes with at least the aforementioned Ornitholestes.[2] This group was named by Andrea Cau, who defined it as the "most inclusive clade containing Vultur gryphus Linnaeus, 1758, and excluding Tyrannosaurus rex Osborn, 1905."[1]

This group of coelurosaurs according to Cau (2018) has the following synapomorphies:[1]

Keel or carinae in the postaxial cervical centra, absence of hyposphene-hypantra in caudal vertebrae (reversal to the plesiomorphic theropodan condition), a prominent dorsomedial process on the semilunate carpal, a convex ventral margin of the pubic foot, a subrectangular distal end of tibia and a sulcus along the posterior margin of the proximal end of fibula.
