The exquisitely preserved integument of Psittacosaurus and the scaly skin of ceratopsian dinosaurs.
Bell PR, Hendrickx C, Pittman M, Kaye TG, Mayr G. Bell PR, et al. Commun Biol. 2022 Aug 12;5(1):809. doi: 10.1038/s42003-022-03749-3. Commun Biol. 2022. PMID: 35962036 Free PMC article. Review.
The Frankfurt specimen of the early-branching ceratopsian dinosaur Psittacosaurus is remarkable for the exquisite preservation of squamous (scaly) skin and other soft tissues that cover almost its entire body. ...Combined with these new integumentary data, a comprehensive …

How Triceratops got its face: An update on the functional evolution of the ceratopsian head.
Nabavizadeh A. Nabavizadeh A. Anat Rec (Hoboken). 2023 Jul;306(7):1951-1968. doi: 10.1002/ar.25196. Epub 2023 Mar 8. Anat Rec (Hoboken). 2023. PMID: 36883781 Review.
Ceratopsian dinosaurs arguably show some of the most extravagant external cranial morphology across all Dinosauria. For over a century, ceratopsian dinosaurs have inspired a multitude of cranial functional studies as more discoveries continued to depict a larger pic …

Modularity and heterochrony in the evolution of the ceratopsian dinosaur frill.
Prieto-Márquez A, Garcia-Porta J, Joshi SH, Norell MA, Makovicky PJ. Prieto-Márquez A, et al. Ecol Evol. 2020 May 22;10(13):6288-6309. doi: 10.1002/ece3.6361. eCollection 2020 Jul. Ecol Evol. 2020. PMID: 32724514 Free PMC article.
Heterochrony has also been invoked in the evolution of the distinctive cranial frill of ceratopsian dinosaurs such as Triceratops. Although ceratopsian frills vary in size, shape, and ornamentation, quantitative analyses that would allow for testing hypotheses of he …

A Ceratopsian Dinosaur from the Lower Cretaceous of Western North America, and the Biogeography of Neoceratopsia.
Farke AA, Maxwell WD, Cifelli RL, Wedel MJ. Farke AA, et al. PLoS One. 2014 Dec 10;9(12):e112055. doi: 10.1371/journal.pone.0112055. eCollection 2014. PLoS One. 2014. PMID: 25494182 Free PMC article.
Biogeographically, A. americanus probably originated via a dispersal from Asia into North America; the exact route of this dispersal is ambiguous, although a Beringian rather than European route seems more likely in light of the absence of ceratopsians in the Early Cretace …

The first ceratopsian dinosaur from South Korea.
Lee YN, Ryan MJ, Kobayashi Y. Lee YN, et al. Naturwissenschaften. 2011 Jan;98(1):39-49. doi: 10.1007/s00114-010-0739-y. Epub 2010 Nov 18. Naturwissenschaften. 2011. PMID: 21085924
In 2008, a new basal neoceratopsian was discovered in the Tando beds (Albian) of Tando Basin in South Korea. It represents the first ceratopsian dinosaur in the Korean peninsula and is assigned to Koreaceratops hwaseongensis gen. et sp. nov. ...

Paleobiological inferences from paleopathological occurrences in the Arctic ceratopsian Pachyrhinosaurus perotorum.
Fiorillo AR, Tykoski RS. Fiorillo AR, et al. Anat Rec (Hoboken). 2023 Jul;306(7):1697-1711. doi: 10.1002/ar.25104. Epub 2022 Oct 22. Anat Rec (Hoboken). 2023. PMID: 36271743
We identify paleopathologies within an assemblage of bones of the pachyrostran centrosaurine Pachyrhinosaurus perotorum, an Arctic ceratopsian. More than 1,000 bones of this dinosaur were collected from the Prince Creek Formation of North Slope, Alaska from fossil sites al …

Three-dimensional geometric morphometric analysis of the skull of Protoceratops andrewsi supports a socio-sexual signalling role for the ceratopsian frill.
Knapp A, Knell RJ, Hone DWE. Knapp A, et al. Proc Biol Sci. 2021 Feb 10;288(1944):20202938. doi: 10.1098/rspb.2020.2938. Epub 2021 Feb 3. Proc Biol Sci. 2021. PMID: 33529562 Free PMC article.
There are, nonetheless, some specific patterns of growth and variation which are expected of traits under socio-sexual selection. The distinctive parietal-squamosal frill of ceratopsian dinosaurs has previously been suggested as a socio-sexual display trait, but evidence f …

A New Taxon of Basal Ceratopsian from China and the Early Evolution of Ceratopsia.
Han F, Forster CA, Clark JM, Xu X. Han F, et al. PLoS One. 2015 Dec 9;10(12):e0143369. doi: 10.1371/journal.pone.0143369. eCollection 2015. PLoS One. 2015. PMID: 26649770 Free PMC article.
Hualianceratops shares several derived characters with both Psittacosaurus and the basal ceratopsians Yinlong, Chaoyangsaurus, and Xuanhuaceratops. A new comprehensive phylogeny of ceratopsians weakly supports both Yinlong and Hualianceratops as chaoyangsaurids (alo …

A Late Cretaceous ceratopsian dinosaur from Europe with Asian affinities.
Osi A, Butler RJ, Weishampel DB. Osi A, et al. Nature. 2010 May 27;465(7297):466-8. doi: 10.1038/nature09019. Nature. 2010. PMID: 20505726
Ceratopsians (horned dinosaurs) represent a highly diverse and abundant radiation of non-avian dinosaurs known primarily from the Cretaceous period (65-145 million years ago). This radiation has been considered to be geographically limited to Asia and western North America …
