Ceratopsids in latest Journal of Paleontology: introducing Albertaceratops!



Two, in fact: one new, the other newly described morphology:

Ryan, M.J. "Palaeoblog". 2007. A NEW BASAL CENTROSAURINE CERATOPSID FROM THE 
OLDMAN FORMATION, SOUTHEASTERN ALBERTA. Journal of
Paleontology 81:376?396.

Abstract:
A new centrosaurine ceratopsid, Albertaceratops nesmoi, is described from the 
lower Oldman Formation (Upper Cretaceous) of southern
Alberta, and is based on a single, almost complete skull. Referred material is 
described from equivalent beds in the Judith River
Formation of north-central Montana. A limited phylogenetic analysis of the 
Ceratopsidae places the new taxon as the basal member of
the Centrosaurinae and indicates that robust, elongate postorbital horncores 
that form a synapomorphy of (Ceratopsidae +
Zuniceratops) are also present in Centrosaurinae.

(ORNITHISCHIA: CERATOPSIDAE). Journal of Paleontology
81:411-414.

No abstract, as this is a "Paleontological Note". However, the abstract would 
basically be the title: confirmation of the presence
of an ossified tendon trellis in a ceratopsid (specifically, the type of _C. 
irvinensis_.)
