Martharaptor is an extinct genus of basal therizinosauroid theropod from the Lower Cretaceous of the Cedar Mountain Formation in Utah.[1]

Hand bones.
Toe bones.

Material and morphology[edit]

The holotype specimen includes fragments of vertebrae, a scapula, forelimb and hindlimb bones, and an ischium. It also includes well-preserved manual unguals. Manual and pedal morphology show that the specimen is distinct from other theropods from the Cedar Mountain Formation and from other previously described therizinosauroids.[1]

Classification[edit]

Phylogenetic analysis placed M. greenriverensis within Therizinosauroidea as the sister taxon to the Alxasaurus + Therizinosauridae group, although support for this placement is weak.[1]

The following cladogram shows the probable placement of Martharaptor within Therizinosauroidea.[1]
