In neoceratopsian dinosaurs, the centra, neural arches, and neural spines of several
anteriormost cervical vertebrae are fused together to form a structure called the cervical bar …

DISCUSSION AND CONCLUSIONS By using Protoceratops andrewsi as an intermediate, it
is possible to interpret the anatomy of the ceratopsid syncervical and establish homologies …

Four or five anterior caudal vertebrae of archaic horned dinosaurs (Protoceratopidae) have
the heterocelous centrum. The cranial and caudal articular surfaces of these centra are …

The anterior cervical vertebrae form the skeletal connection between the cranial and
postcranial skeletons in higher tetrapods. As a result, the morphology of the atlas-axis …

Two monographs and a large number of shorter papers represent the many valuable
contributions to the study of the ceratopsian dinosaurs. There are, however, still several …

Cervical vertebrae of six horned dinosaurs from the Upper Cretaceous of Mongolia, which
are identified as Protoceratops andrewsi are examined. It is shown that vertebrae of the …

Basal (cladistically) neoceratopsians are relatively small, gracile members of Ceratopsia
('horned” dinosaurs), which also includes larger forms such as Triceratops and …

The cranial anatomy of ceratopsian (“horned”) dinosaurs is well understood, but the
postcranial skeleton has been largely ignored in previous studies of phylogeny, evolution …

ABSTRACT The Extant Phylogenetic Bracket approach is applied to infer the kind of soft
tissue that would have been associated with the bifurcated neural spines of the cervical …

Hongshanosaurus houi, and basal neoceratopsians such as Liaoceratops yanzigouensis.
The excellent preservation and preparation of this fossil material now allows for new …
