Inner Ear Anatomy of Caenagnathidae (Theropoda: Oviraptorosauria) Emphasizes Mosaic Evolution of the Avian Neurosensory System. [PDF]
Journal of Comparative NeurologyABSTRACT The endocranial anatomy of oviraptorosaurian theropods, and their inferred sensory adaptations, has played a key role in understanding the origin of bird‐like senses among avian ancestors. However, within oviraptorosaurs, sampling has thus far been limited, and a major gap exists in our understanding of the endocranial ...

A New Large-Bodied Oviraptorosaurian Theropod Dinosaur from the Latest Cretaceous of Western North America [PDF]
PLoS ONE, 2014 The oviraptorosaurian theropod dinosaur clade Caenagnathidae has long been enigmatic due to the incomplete nature of nearly all described fossils. Here we describe Anzu wyliei gen. et sp.

The diet of early birds based on modern and fossil evidence and a new framework for its reconstruction. [PDF]
Biol Rev Camb Philos Soc, 2021 ABSTRACT Birds are some of the most diverse organisms on Earth, with species inhabiting a wide variety of niches across every major biome. As such, birds are vital to our understanding of modern ecosystems. Unfortunately, our understanding of the evolutionary history of modern ecosystems is hampered by knowledge gaps in the origin of modern bird ...

A new oviraptorosaur (Dinosauria: Theropoda) from the end-Maastrichtian Hell Creek Formation of North America. [PDF]
PLoS ONECaenagnathidae is a clade of derived, Late Cretaceous oviraptorosaurian theropods from Asia and North America. Because their remains are rare and often fragmentary, caenagnathid diversity is poorly understood. Anzu wyliei is the only caenagnathid species

Bulletin of the Peabody Museum of Natural History, 2013 Caenagnathid theropods are a relatively common part of the theropod fauna in the Late Cretaceous of Asia and North America, but have not previously been described from the southernmost United States. Here, we describe caenagnathid fossils from the late Campanian Aguja Formation of West Texas, and revise the systematics of caenagnathids from the ...

Osteohistological analysis of metatarsals reveals new information on pathology and life history of troodontids from the Campanian Dinosaur Park Formation, Alberta, Canada. [PDF]
J AnatA histological survey of troodontid metatarsals from the Dinosaur Park Formation (DPF) was conducted, revealing correlates for stresses in the troodontid arctometatarsus and providing the first histological assessment of pathologies for this taxon.

A caenagnathid oviraptorosaur metatarsal from the Mesaverde Formation (Campanian), Wyoming
Vertebrate Anatomy, Morphology, Palaeontology, 2021 A well-preserved left theropod metatarsal I from the Campanian Mesaverde Formation of Wyoming is described and identified as belonging to a caenagnathid, representing the first occurrence of this clade from the formation.

Vertebrate Anatomy, Morphology, Palaeontology, 2020 Our understanding of caenagnathid anatomy, diversity, and ecology has improved considerably in the past twenty years, but numerous issues still remain. Among these, the diversity and taxonomy of caenagnathids from the Dinosaur Park Formation of Alberta,
