THE DIET OF OSTRICH DINOSAURS (THEROPODA: ORNITHOMIMOSAURIA) [PDF]
Palaeontology, 2005 : The diets of ornithomimosaurian dinosaurs (Theropoda: Ornithomimosauria) have proved to be contentious owing to a dearth of unambiguous evidence in support of carnivory, omnivory or herbivory. Re-assessment of anatomical, taphonomical and palaeoecological evidence, and estimates of daily minimal energy budgets for two derived ornithomimosaurian ...

The oldest record of Alvarezsauridae (Dinosauria: Theropoda) in the Northern Hemisphere
PLOS ONE, 2017 Procoelous caudal vertebrae, a carpometacarpus with a hypertrophied metacarpal II, and robust proximal and ungual phalanges of manual digit II of a small theropod dinosaur from the Upper Cretaceous (Turonian) Bissekty Formation at Dzharakuduk, Uzbekistan, show unequivocal synapomorphies of the clade Alvarezsauridae and thus are referred to it.
