A New Horned Dinosaur Reveals Convergent Evolution in Cranial Ornamentation in Ceratopsidae [PDF]

open access: yesCurrent Biology, 2015
Ceratopsid (horned) dinosaurs are an iconic group of large-bodied, quadrupedal, herbivorous dinosaurs that evolved in the Late Cretaceous and were largely restricted to western North America [1-5]. Ceratopsids are easily recognized by their cranial ornamentation in the form of nasal and postorbital horns and frill (capped by epiossifications); these ...

The oldest centrosaurine: a new ceratopsid dinosaur (Dinosauria: Ceratopsidae) from the Allison Member of the Menefee Formation (Upper Cretaceous, early Campanian), northwestern New Mexico, USA

Palaontologische Zeitschrift, 2021
An associated incomplete skeleton of a ceratopsid dinosaur from the Campanian deposits of the Allison Member of the Menefee Formation in New Mexico, USA is described. Although it was originally described over two decades ago, newly prepared portions of the Menefee Formation skeleton and reinterpretations of previously known morphology, in addition to ...

AN OSSIFIED TENDON TRELLIS IN CHASMOSAURUS (ORNITHISCHIA: CERATOPSIDAE)

Journal of Paleontology, 2007
The ornithischia and its sister group, the Saurischia, comprise the Dinosauria. Ornithischians (Weishampel, 2004) are a diverse group of primarily quadrupedal herbivores that include such familiar dinosaurs as the armored stegosaurs and ankylosaurs (Thyreophora), as well as the duckbilled hadrosaurs, pachycephalosaurs, and ceratopsians (Cerapoda).

Family CERATOPSIDAE Three genera of neoceratopsians are known from the Maastrichtian of the Western Interior: Triceratops, Diceratops, and Torosaurus (Forster, 1996; however, see Lehman, 1987). In addition, Triceratops is represented by two species: T. horridus and T. porosus.

A complete skull of Chasmosaurus mariscalensis (Dinosauria: Ceratopsidae) from the Aguja Formation (late Campanian) of West Texas

Journal of Vertebrate Paleontology, 1993
ABSTRACT The recent discovery of a nearly complete ceratopsid skull in the Aguja Formation of southwest Texas supports previous conclusions that the Aguja ceratopsid represents a distinct species, Chasmosaurus mariscalensis. The diagnostic features of C.

Cranial morphology and systematics ofChasmosaurus(Dinosauria: Ceratopsidae) from the Upper Cretaceous of western Canada

Journal of Vertebrate Paleontology, 1995
ABSTRACT The ceratopsid dinosaur genus Chasmosaurus from the Judith River Formation (Campanian; Judithian) of western Canada shows considerable variability in cranial morphology due in part to an unusually long ontogenetic trajectory. Nevertheless, two more or less distinct morphs can be identified.

MORPHOLOGY AND ONTOGENY OF THE CORNUAL SINUSES IN CHASMOSAURINE DINOSAURS (ORNITHISCHIA: CERATOPSIDAE)

Journal of Paleontology, 2006
Ceratopsids, horned herbivorous ornithischians from the Cretaceous of North America, are unique among dinosaurs in the form and expression of their cranial ornamentation. All ceratopsid genera possess a bony parieto-squamosal frill that projects over the neck region and some degree of development of nasal and orbital horns. These horns vary in form and
