A DROMAEOSAURID VERTEBRA FROM THE DINOSAUR PARK FORMATION (UPPER CRETACEOUS, CAMPANIAN) OF ALBERTA

, 2022
An isolated posterior dorsal vertebra of the dromaeosaurid theropod in the San Diego Natural History Museum found from the Dinosaur Park Formation (Campanian) of southern Alberta is described. The vertebra has morphological affinities to the corresponding elements of Saurornitholestes langstoni, although the lack of comparative materials as well as ...

Evolutionary palaeoecology of the megaherbivorous dinosaurs from the Dinosaur Park Formation (upper Campanian) of Alberta, Canada

, 2012
During the Late Cretaceous, megaherbivorous dinosaurs flourished in the Western Interior of North America (Laramidia). At any one time, there were typically two ankylosaurs (one ankylosaurid plus one nodosaurid), two ceratopsids (one centrosaurine plus one chasmosaurine), and two hadrosaurids (one hadrosaurine plus one lambeosaurine) living in sympatry.

DINOSAUR FOOTPRINTS FROM THE GLEN ROSE FORMATION (PALUXY RIVER, DINOSAUR VALLEY STATE PARK, SOMERVELL COUNTY, TEXAS)

, 2015
Dinosaur footprints are found in the Glen Rose Formation and other Lower Cretaceous stratigraphic units over much of central Texas (Pittman, 1989; Rogers, 2002; Farlow et al., 2006). Dinosaur tracks \ud were discovered in the rocky bed of the Paluxy River, near the town of Glen Rose, Texas, early in the 20th Century (Jasinski, 2008; Farlow et al ...
