For decades, a massive fossil unearthed on Vancouver Island puzzled scientists. Now, this incredible marine reptile, first discovered 37 years ago, has been officially identified as a completely new genus and species: Traskasaura sandrae. This fascinating discovery adds a new chapter to British Columbia’s rich paleontological history and honors the father and daughter who first found it.

The story begins in 1987, along the Puntledge River near Courtenay on Vancouver Island. Fossil enthusiast Mike Trask and his then 12-year-old daughter, Heather, stumbled upon the fossilized remains of a huge creature. It was clearly a type of plesiosaur, a group of marine reptiles famous for their long necks (like the Loch Ness Monster, if it were real and ancient!). Early assessments often placed it within the elasmosaur family, known for extremely long necks.

Unlocking a Prehistoric Mystery
For many years, the exact identity of this particular fossil remained a mystery. While recognized as significant – it was even declared British Columbia’s official fossil emblem in 2023 – scientists needed more definitive evidence to classify it precisely. The fossilization process had caused some corrosion, making a clear identification challenging.
The breakthrough came when Mike’s twin brother, Pat Trask, who is the curator of natural history at the Courtenay Museum, made his own discovery in 2020. He found a better-preserved fossil of the same type of animal, also in the Courtenay-Comox area.
The Missing Piece of the Puzzle
This second specimen provided the crucial details researchers needed. Led by F. Robin O’Keefe, a professor at Marshall University, scientists were able to study both fossils together. Their detailed analysis revealed that the features of these reptiles were distinct enough to warrant their own unique classification, separate from other known elasmosaurs.
In findings recently published in the Journal of Systematic Paleontology, they formally described the animal as a “very odd new genus” of the plesiosaur family. They named it Traskasaura sandrae, a poignant tribute to Mike Trask and his daughter Sandra. Sadly, Heather Trask passed away in 2023, and Mike Trask passed away just days before the study was published, but he knew the official identification was coming and was reportedly very happy and grateful.
What Was Traskasaura Like?
Living around 85 million years ago during the Cretaceous period, the Traskasaura was a formidable predator in the ancient seas that covered parts of British Columbia. At approximately 12 meters long (about the length of a school bus), it was a large marine reptile.
One particularly striking feature highlighted by researchers is its teeth: described as “heavy, sharp, robust teeth ideal for crushing.” This suggests Traskasaura wasn’t just grabbing slippery fish; it might have been equipped to tackle prey with shells or hard exoskeletons, offering clues about its diet and role in the ancient marine ecosystem.
Fossil footprints from armored dinosaurs with tail clubs have also been discovered in British Columbia and Alberta, hinting at the region’s rich prehistoric past.
A Legacy Preserved in Stone
The formal identification of Traskasaura sandrae is a significant moment in paleontology. It confirms the unique nature of a fossil that has been a source of local pride and curiosity for decades. It validates the efforts of Mike and Heather Trask, whose initial discovery sparked the journey leading to this scientific recognition.
The fossils are now housed and displayed at the Courtenay Museum and Palaeontology Centre, serving as a tangible link to British Columbia’s deep past and a testament to the legacy of its discoverers. The Traskasaura now stands proudly as a scientifically confirmed, unique species, alongside other provincial emblems like the Pacific dogwood and Stellar’s jay.
Researchers continue to make dinosaur fossil discoveries in northern British Columbia and other parts of Canada, expanding our knowledge of prehistoric life.
This research underscores the importance of amateur fossil hunters and local museums in contributing to global scientific understanding. It reminds us that incredible discoveries are still waiting to be made, often thanks to the sharp eyes and dedication of people passionate about the ancient world. The Traskasaura sandrae is more than just a fossil; it’s a story of curiosity, perseverance, and a lasting legacy in stone.
