Filling in Gaps in the Ceratopsid Histologic Database: Histology of Two Basal Centrosaurines and an Assessment of the Utility of Rib Histology in the Ceratopsidae [PDF]
The Anatomical Record, 2019 ABSTRACTBone histology grants substantial insight into the growth and biology of fossil vertebrates. Many of the major non‐avian dinosaurian clades have been extensively sampled for bone histologic data allowing reconstruction of their growth as well as the assessment of the evolution of growth changes along phylogenies.

DiversityVery few remains of ceratopsid dinosaurs have been recovered so far from the Difunta Group of Coahuila, Mexico. The enigmatic chasmosaurine Coahuilaceratops magnacuerna was previously described on the basis of two partial skulls purportedly derived from ...

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs
The Anatomical Record, EarlyView.Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

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 ...

An osteohistological analysis of Triceratops (Ornithischia: Ceratopsidae) cranial ornamentation
The Anatomical RecordAbstract Ceratopsids are among the most distinctive and well known extinct Cretaceous vertebrates, yet many details regarding the growth and composition of their cranial features are still not fully anatomically described or understood.

HINDLIMB OF AN INDETERMINATE CERATOPSID DINOSAUR One of us (BT) created a reconstruction of UALVP 42, an indeterminate ceratopsid left partial hindlimb comprising almost all the crural and pedal elements, to explore and illustrate the articular configuration of the lower hindlimb in Ceratopsidae for a future descriptive paper (Theurer et al.

, 1972 FAMILY CERATOPSIDAE Figure 9G, H Although worn ceratopsian teeth form a sizable portion of the ornithischian remains, they cannot be differentiated at the generic level. Unworn teeth indicate that at least two genera of ceratopsians may have been present.
