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
