Horned dinosaurs of Dinosaur Provincial Park featured at Speaker Series
James Campbell, Ph.D. student, at the Department of Biological Sciences, University of Calgary, will be presenting a talk called “A Re-evaluation of Horned Dinosaurs from Southern Alberta” at Speaker Series.
The April 13 session of the 2017 Royal Tyrrell Museum’s Speaker Series is a presentation by James Campbell, Ph.D. student, Department of Biological Sciences, University of Calgary, entitled “A Re-evaluation of Horned Dinosaurs from Southern Alberta.”
Alberta is one of the best places in the world to find horned dinosaurs; herbivores with large skulls and often intricate horns and neck frills. As many as 11 different species of horned dinosaurs have been found in Dinosaur Provincial Park alone.
Despite their relative abundance, it can be difficult to assign their fossils to a specific species and to know exactly what time during the Late Cretaceous they lived.
Palaeontologists rely on skeletal material, rather than DNA, and dating methods give a range of time, not a specific date. For example, Chasmosaurus russelli and Chasmosaurus belli have traditionally been considered separate species based on their frills and horns. It is also believed that they lived at separate times, with C. belli replacing C. russelli and then being replaced by a third horned dinosaur, Vagaceratops irvinensis.
In his talk, Campbell will discuss his investigation of these three horned dinosaurs from Dinosaur Provincial Park, including whether C. belli and C. russelli are truly distinct species, when all three lived, and whether all of the known skulls have been assigned to the correct species. As this is new, unpublished research, the talk will not be made available online, so make sure to attend the presentation in person.
The Royal Tyrrell Museum’s Speaker Series talks are free and open to the public. They are held every Thursday until April 27 at 11:00 a.m. in the Museum auditorium. Past Speaker Series talks are also available on the Museum’s YouTube channel: youtube. com/user/RoyalTyrrellMuseum
