Anatomy ofMahakala omnogovae(Theropoda: Dromaeosauridae), Tögrögiin Shiree, Mongolia [PDF]

American Museum Novitates, 2011
ABSTRACT The dromaeosaurid Mahakala omnogovae is known from a unique specimen from the Late Cretaceous deposits of the Djadokhta Formation at Togrogiin Shiree, Omnogov Aimag, Mongolia. The holotype specimen is comprised of a well-preserved but partial skull and a nearly complete postcranial skeleton.

A microraptorine (Dinosauria–Dromaeosauridae) from the Late Cretaceous of North America [PDF]

Proceedings of the National Academy of Sciences, 2009
The fossil assemblages of the Late Cretaceous of North America are dominated by large-bodied dinosaur species. Associated skeletons of small dinosaurs are exceedingly rare, and small (<10 kg) carnivorous theropods have not previously been reported from these beds.

Feeding habits of the Middle Triassic pseudosuchian Batrachotomus kupferzellensis from Germany and palaeoecological implications for archosaurs

Palaeontology, Volume 65, Issue 3, May/June 2022., 2022
Abstract Bite traces on fossil bones are key to deciphering feeding ecology and trophic interactions of vertebrate past ecosystems. However, similarities between traces produced by different carnivorous taxa with similar dentitions, and misidentifications due to equifinality, hinder confident identifications of the bite makers.

Upper Cretaceous European theropod palaeobiodiversity, palaeobiogeography and the intra‐Maastrichtian faunal turnover: new contributions from the Iberian fossil site of Laño

Papers in Palaeontology, Volume 8, Issue 1, January/February 2022., 2022
Abstract A total of 227 theropod teeth have so far been recovered from the upper Campanian Laño site (northern Iberian Peninsula). The teeth were studied for their qualitative and quantitative features. From the theropod sample found at Laño, seven morphotypes attributed to five taxa are identified: a medium to large abelisaurid (Arcovenator sp.) and ...

Skull morphology and histology indicate the presence of an unexpected buccal soft tissue structure in dinosaurs. [PDF]

J Anat
A combined approach of osteology and histology was used to examine the cheek regions of dinosaurs. Strong evidence was found for a soft tissue in this region connecting the zygoma to the mandible, here named the ‘exoparia’. Abstract Unlike mammals, reptiles typically lack large muscles and ligaments that connect the zygoma to the mandible.

The first dromaeosaurid (Dinosauria: Theropoda) from the Lower Cretaceous Bayan Gobi Formation of Nei Mongol, China [PDF]

PeerJ, 2015
The first dromaeosaurid theropod from the Lower Cretaceous Bayan Gobi Formation is identified based on an incompletely preserved partially-articulated left leg, increasing the known diversity of its understudied ecosystem.

New Specimens of Microraptor zhaoianus (Theropoda: Dromaeosauridae) from Northeastern China

American Museum Novitates, 2002
Abstract New specimens of the diminutive theropod dinosaur Microraptor zhaoianus are described. These specimens preserve significant morphological details that are not present or are poorly preserved in the holotype specimen, including aspects of the manus, pectoral girdle, dorsal vertebrae, ilium, and sacrum.
