The Phylogeny of Ceratosauria (Dinosauria: Theropoda)

Journal of Systematic Palaeontology, 2008
Synopsis Recent discoveries and analyses have drawn increased attention to Ceratosauria, a taxonomically and morphologically diverse group of basal theropods. By the time of its first appearance in the Late Jurassic, the group was probably globally distributed.

A New Specimen of Sinosaurus triassicus (Dinosauria: Theropoda) from the Early Jurassic of Lufeng, Yunnan, China

Historical Biology, 2023
The holotype of Sinosaurus triassicus is poorly preserved, and no previous research has focused exclusively on its anatomy. This research reports a new specimen recovered near the locality of the holotype of S.

A Review of Small-Bodied Theropod Dinosaurs from the Upper Cretaceous of India, with Description of New Cranial Remains of a Noasaurid (Theropoda: Abelisauria)

Journal of Vertebrate Paleontology, 2023
Small-bodied theropod dinosaurs are rare on southern landmasses but have been known from India for a century. Excavations by Charles Matley and Durgansankar Bhattacharji in uppermost Cretaceous sediments at Bara Simla, central India in 1917–1919 ...

Osteology of the two-fingered oviraptorid Oksoko avarsan (Theropoda: Oviraptorosauria)

Zoological Journal of the Linnean Society
Oviraptorosaurs are among the most diverse and best-known extinct theropod groups. Their bizarre anatomy and their social and reproductive behaviour are now well understood.

Opinion 2486 (Case 3506) – Allosaurus Marsh, 1877 (Dinosauria, Theropoda): usage conserved by designation of a neotype for its type species Allosaurus fragilis Marsh, 1877

Bulletin of Zoological Nomenclature, 2023
. The International Commission on Zoological Nomenclature has used its plenary power to conserve the usage of the name Allosaurus Marsh, 1877, by designating specimen USNM 4734 as the neotype to replace the nondiagnostic holotype (YPM 1930) of Allosaurus

Elemgasem nubilus: a new brachyrostran abelisaurid (Theropoda, Ceratosauria) from the Portezuelo Formation (Upper Cretaceous) of Patagonia, Argentina

Papers in Palaeontology, 2022
Abelisaurids are medium–large‐sized theropod dinosaurs that were predominant in the carnivorous fauna during the Late Cretaceous of Gondwana. These predators are abundant in the Cretaceous fossil strata of Patagonia, which yield the best record for this ...

A new Urbacodon (Theropoda, Troodontidae) from the Upper Cretaceous Iren Dabasu Formation, China: Implications for troodontid phylogeny and tooth biology

Cladistics
Tooth attachment and replacement play significant roles in the feeding ecology of polyphyodont vertebrates, yet these aspects have remained largely unexplored in non‐avialan paravians including troodontids.
