When & Where 

Coronosaurus lived during the Middle Campanian Stage of the Late Cretaceous period, approximately 77 million years ago.

Its fossil remains were first recovered by Phillip J. Currie in 1996. It was followed by another discovery in 2000 in Oldman Formation. It was given the name of Coronosaurus brinkmann which was named after Donald Brinkman for his outstanding contribution to the research of paleoecology in Alberta (Late Cretaceous environments).

Size & Weight

One of the biggest dinosaurs of its time. It measured 16’ in length and 13 ft tall. It was even very heavy and weighed about 8960 lbs (4064.2 kg).

Mobility & Diet

They used to feast with various plant materials like plants, roots, shoots and stems. Though they were herbivores, they were considered to be quite aggressive. 

Interesting Points

  • The discovery of Coronosaurus was a significant development in understanding the paleontology of Triceratopsidae dinosaurs’ early evolution.
  • It had large frills and many horns on its head.
  • Several species were discovered but the Coronosaurus brinkmani species was the most popular. 
  • A partial skull of Coronosaurus is currently displayed in the Royal Tyrell Museum.
