Ornithomimoides

Huene & Matley, 1933 or-NITH-o-mie-MOI-deez Nomen dubium

From Greek 'ornis' (bird), 'mimos' (mimic), and '-oides' (resembling); meaning 'bird mimic-like', indicating resemblance to ornithomimosaurs.

Ornithomimoides is a dubious genus of theropod dinosaur from the Late Cretaceous (Maastrichtian) Lameta Formation of India. The type species, O. mobilis, and the doubtfully referred O.? barasimlensis were named and described by Huene and Matley in 1933, and are known only from isolated vertebrae of the Lameta "Carnosaur bed"; O. mobilis is based on five large vertebrae and O.? barasimlensis on a smaller set. Novas and colleagues (2004) reinterpreted the type vertebrae as proximal caudals of an indeterminate abelisauroid and, finding no diagnostic features, considered the genus a nomen dubium.

    Reinterprets the type vertebrae of Ornithomimoides as proximal caudals of an indeterminate abelisauroid; finding no autapomorphies, treats the genus as a nomen dubium.

    Refers Ornithomimoides mobilis to Abelisauridae and O.? barasimlensis to Noasauridae, and suggests several Lameta names represent one or two taxa.

    Proposes, in a conference abstract, that Ornithomimoides shares autapomorphies with Coeluroides and should be grouped with it under that name.
