A 2003 Discovery That Rewrote Ancient History
The remote wilderness of British Columbia, where ancient secrets lay hidden for millions of years, waiting for the right moment to reveal themselves.
In the summer of 2003, a team of geologists mapping in the rugged wilderness of northern British Columbia stumbled upon an extraordinary find. In the Bowser Basin, north of the city of Terrace, they discovered dinosaur foot imprints and a fossilized turtle shell 3 .
This was not just another fossil discovery; these were the most westerly dinosaur track remains ever found in British Columbia and the third most westerly in all of North America 3 . The fossils, confirmed to be from the early Cretaceous period, opened a thrilling new window into a prehistoric world, providing the first evidence that dinosaurs once roamed the lands of ancestral British Columbia, trekking across the continent to gaze upon the western ocean 3 .

The discovery was part of a larger, $4-million multidisciplinary geoscience program led by the Geological Survey of Canada and the B.C. Ministry of Energy and Mines 3 . This program, which included partners from Simon Fraser University and the University of Alberta, was designed to collect baseline geological data to aid oil and gas exploration 3 .
The first fieldwork in the summer of 2003 focused on the eastern parts of the Bowser and Sustut basins, an area covering a massive 65,000 square kilometres of Jurassic and Cretaceous sedimentary rocks 3 . It was during this season, in the central part of Bowser Basin, that the dinosaur fossils were unearthed, proving that resource development could indeed help unlock the secrets of our deep past 3 .
Discovered by Professor Peter Mustard from Simon Fraser University's Department of Earth Sciences, these trace fossils are footprints left by dinosaurs as they moved across the ancient landscape 3 . Unlike bones, which can be washed away after death, tracks record a moment of activity, freezing a behavior in time.
Found by Mike Boddy, a geologist with B.C.'s Ministry of Energy and Mines, this was an exceptionally rare discovery for western North America 3 . A turtle skeleton of this age provides crucial information about the ecosystem beyond the dinosaurs that dominated it.
This first-time evidence shows these dinosaurs crossed the prehistoric North American continent over the newly formed landscape of ancestral British Columbia to gaze upon the western ocean.3
The dinosaur tracks and turtle remains found in British Columbia are examples of trace fossils and body fossils, respectively. Their preservation is a remarkable process that requires a precise set of conditions.
Recent research has shed light on the critical role microorganisms play in the preservation of fossils. Bacteria can act as catalysts for the early mineralization of organic materials, which is essential for an organism to be preserved in the fossil record 4 .
Laboratory experiments have shown that cyanobacteria and their metabolic products are instrumental in the formation of carbonate minerals and the accumulation of layered rock structures called stromatolites 4 . This process, where living organisms influence the creation of minerals, is known as biomineralization.
Organism dies and is quickly buried by sediment, protecting it from scavengers and decay.
Minerals from groundwater gradually replace organic materials, a process often aided by bacteria 4 .
Sediments compact and harden into rock over millions of years under pressure.
Erosion or human activity exposes the fossil, allowing discovery.
The discovery of the 2003 fossils was not accidental; it was the result of systematic work using specific tools and methods. The following table outlines the key "research reagent solutions" and equipment essential for a geological field season aimed at fossil discovery and geological mapping.
| Tool or Reagent | Function in the Field |
|---|---|
| Geological Map & GPS | Navigation and precise recording of sample locations and geological contacts. |
| Rock Hammer & Chisel | Extracting rock samples and carefully excavating fossils from the surrounding matrix. |
| Field Notebook & Camera | Documenting observations, stratigraphy, and the context of finds with notes and images. |
| Sample Bags & Labels | Securing and organizing rock and fossil specimens with critical contextual data. |
| Hand Lens | Identifying mineral compositions and small-scale fossil structures in the field. |
| Geological Compass | Measuring the orientation of rock layers, which helps reconstruct the ancient environment. |
Today's paleontologists also use advanced technologies like ground-penetrating radar, 3D scanning, and chemical analysis to uncover and study fossils without damaging them.
The fossils from the Bowser Basin paint a picture of a vibrant ecosystem. The early Cretaceous period was a time when the continents were closer together, and the climate was generally warmer than today. The presence of both dinosaur tracks and a turtle skeleton suggests a landscape that included water sources, such as rivers or lakes, surrounded by vegetation that supported a diverse community of animals.
Professor Mustard noted that the abundance of plant material, turtle remains, and dinosaur tracks in the area strongly indicates that the region is rich in fossils and that the discovery of dinosaur bones is a likely possibility for future expeditions 3 .
| Aspect of the Ecosystem | Evidence from Bowser Basin |
|---|---|
| Geological Age | Early Cretaceous Period (144-65 million years ago) 3 |
| Representative Animals | Dinosaurs (from footprints), freshwater turtles 3 |
| Environment | Land-based and freshwater habitats, likely near the ancient west coast 3 |
| Plant Life | Abundant plant material discovered alongside animal fossils 3 |
| Preservation Potential | High, indicated by the diversity and rarity of the fossils found 3 |
The 2003 regional discovery in British Columbia's Bowser Basin did more than just add a new pin to the map of dinosaur fossils; it fundamentally changed our understanding of the prehistoric geography of North America. It proved that dinosaurs journeyed to the very edge of the western continent.
The findings underscored the importance of government-funded geoscience programs, which, while aimed at resource management, have the powerful secondary benefit of unlocking chapters of our planetary history.
The fossils, now part of the Royal British Columbia Museum collection and available for public viewing, stand as a testament to a time when dinosaurs walked the lands that would become British Columbia 3 . They ignite the imagination and remind us that groundbreaking discoveries often lie just beneath our feet, waiting for a curious mind to find them. As the energy and mines minister at the time noted, "Who knows what else is out there waiting to be discovered?" 3
