Historical BiologyThe upper Campanian tyrannosaurine Daspletosaurus horneri was originally described based solely on specimens from the Two Medicine Formation of Montana, U.S.A.. Here, a taxonomic reassessment of a stratigraphically high occurrence of a Daspletosaurus specimen, CMN 350, from the Dinosaur Park Formation provides the first evidence of D.

New fossil lizard specimens from a poorly-known squamate assemblage in the Upper Cretaceous (Campanian) San Juan Basin, New Mexico, USA [PDF]
PeerJ, 2020 Recent collection efforts in the upper Campanian (∼76-73.5 Ma) Fruitland and Kirtland formations of northwestern New Mexico have significantly increased the taxonomic diversity of lizards in this historically poorly understood squamate assemblage.

Pararhabdodon Isonensis and Tsintaosaurus Spinorhinus: A New Clade of Lambeosaurine Hadrosaurids from Eurasia [PDF]
, 2009 We present new anatomical information showing that Koutalisaurus kohlerorum, from the Maastrichtian of Lleida Province, northeastern Spain, is most probably the junior synonym of Pararhabdodon isonensis from the same region.

The Anatomical Record, 2022 AbstractCounts of the number of skeletal specimens of “adult” megaherbivores and large theropods from the Morrison and Dinosaur Park formations—if not biased by taphonomic artifacts—suggest that the big meat‐eaters were more abundant, relative to the number of big plant‐eaters, than one would expect on the basis of the relative abundance of large ...

PLoS ONE, 2013 Few ankylosaurs are known from more than a single specimen, but the ankylosaurid Euoplocephalus tutus (from the Late Cretaceous of Alberta, Canada and Montana, USA) is represented by dozens of skulls and partial skeletons, and is therefore an important ...
