The first ornithomimosaur remains from Germany [PDF]

Acta Palaeontologica Polonica
Ornithomimosauria is a group of coelurosaurs primarily known from the Cretaceous of Asia and North America. The European record is comparatively sparse, with Pelecanimimus from the Lower Cretaceous of Spain being the only unequivocal representative. Here,

Rebuttal of McFeeters, Ryan and Cullen, 2018, ‘Positional variation in pedal unguals of North American ornithomimids (Dinosauria, Theropoda): A Response to Brownstein (2017)’

Vertebrate Anatomy, Morphology, Palaeontology, 2018
The Arundel Clay of Maryland is among the only Early Cretaceous terrestrial units known from eastern North America. Research on some theropod dinosaur bones from this layer has indicated the presence of two ornithomimosaur taxa in the assemblage. However,

Elevated evolutionary rates of biting biomechanics reveal patterns of extraordinary craniodental adaptations in some herbivorous dinosaurs [PDF]

Palaeontology, Volume 67, Issue 1, January/February 2024.
Abstract Adaptation to specialist ecological niches is a key innovation that has contributed to the evolutionary success of many vertebrate clades, underpinning the acquisition of diverse skull morphologies. Dinosaurs, which dominated Mesozoic terrestrial faunas, acquired herbivory multiple times, and evolution of these herbivorous adaptations is ...

<b>Inside the head of <i>Pelecanimimus polyodon</i> (Ornithomimosauria, Dinosauria): Occipital palaeoneuroanatomy of the early branching ornithomimosaur from Las Hoyas fossil site (Early Cretaceous, Cuenca, Spain).</b>

Spanish Journal of Paleontology
Ornithomimosauria is a striking theropod dinosaur group whose unusual traits have generated debate about several behaviours related to diet and lifestyle. Although the palaeoneuroanatomy might provide valuable information to palaeobiological studies of this group, these studies are scarce.

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica. [PDF]

Anat Rec (Hoboken)
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Body size and evolutionary rate analyses reveal complex evolutionary history of Alvarezsauria. [PDF]

Cladistics
Abstract Some of the smallest examples of dinosaurian body size are from alvarezsaurians, an enigmatic group of maniraptoran coelurosaurians with a peculiar combination of anatomical features unique among theropods. Despite the large number of alvarezsaurian species described worldwide and the increased understanding this has provided, the body‐size ...

Modified skulls but conservative brains? The palaeoneurology and endocranial anatomy of baryonychine dinosaurs (Theropoda: Spinosauridae). [PDF]

J Anat, 2023
Spinosaurids were unusual large‐bodied tetanuran theropods with semi‐aquatic ecologies. The neuroanatomy of baryonychine spinosaurids has yet to be studied, and may inform about the early evolution of the spinosaurid brain and sensory capabilities. With unexceptional hearing and olfaction, baryonychine endocasts share morphological similarities with ...

Chronic fracture and osteomyelitis in a large‐bodied ornithomimosaur with implications for the identification of unusual endosteal bone in the fossil record

The Anatomical Record, Volume 306, Issue 7, Page 1864-1879, July 2023., 2023
Abstract Paleopathological diagnoses provide key information on the macroevolutionary origin of disease as well as behavioral and physiological inferences that are inaccessible via direct observation of extinct organisms. Here we describe the external gross morphology and internal architecture of a pathologic right second metatarsal (MMNS VP‐6332) of a
