Searching for the Sexes in Dinosaur Horns

Explore the fascinating world of dinosaur paleontology in this Speaker Series lecture from the Royal Tyrrell Museum. Delve into Benjamin Borkovic's research on sexual dimorphism in dinosaur horns, focusing on Centrosaurus and Triceratops. Learn about the methods used to study sexual differences in modern animals like mountain goats, bison, and pronghorn, and how these techniques are applied to fossil specimens. Discover the challenges of determining age and sex in dinosaurs, and gain insights into the ontogeny and measurements of ceratopsian dinosaurs. Examine the results and conclusions drawn from this groundbreaking study, and understand the implications for our understanding of dinosaur biology and evolution.
