Caleb Brown, Ph.D.

Curator of Dinosaur Systematics & Evolution

Caleb Brown studies the diversity of dinosaurs from the Cretaceous Period of Alberta, and their evolutionary relationships. One aspect of Caleb's research investigates taphonomy (the study of influences on preservation and fossilization). He specifically looks at how preservation biases in environments shape our understanding of ancient ecosystems. Caleb is also very interested in the evolution and variation in the display structures of horned dinosaurs.

Research Interests

  • The diversity and biology of herbivorous dinosaurs, including the anatomy and evolution of display structures (horns, frills, and crests).
  • The diversity and preservation of small-bodied dinosaurs.
  • Taphonomy (the study of influences on preservation and fossilization).

Professional Highlights

  • A lead researcher on Borealopelta markmitchelli, the world's best-preserved armoured dinosaur.
  • A lead researcher on Regaliceratops peterhewsi, a new species of ceratopsian that provides insights into horned dinosaur evolution.
  • Documented preservation biases against small dinosaurs in Dinosaur Park Formation, and implications for understanding of dinosaur-dominated ecosystems.
  • Discovered the holotype of Acrotholus, North America's oldest pachycephalosaur.

Education

Ph.D., University of Toronto, 2013
