Earth scientist Guy Plint discovered rare duck-billed dinosaur tracks in Tumbler Ridge, British Columbia, while studying sedimentary formations [1].
These findings provide critical evidence of the prehistoric landscape and the movement of dinosaur species across an ancient delta. The discovery allows researchers to reconstruct the environment of the region from millions of years ago.
Plint first encountered the tracks in 1988 [1]. At the time, his primary research was focused on sedimentary studies rather than paleontology [2]. While examining the geological layers of the area, he found footprints left by duck-billed dinosaurs in formations that are 86 million years old [1].
The presence of these tracks suggests that the area was once a lush, water-rich environment. Because the tracks were preserved in sedimentary rock, they offer a physical record of how these animals interacted with their surroundings, a detail often missing from skeletal remains.
“These tracks are a window into an ancient delta environment,” Plint said [1].
Research published in 2023 further highlighted the significance of these fossil discoveries [2]. The data suggests that the Tumbler Ridge site is a vital location for understanding the distribution of dinosaur species in North America during the Cretaceous period. The preservation of the trackways allows scientists to study the gait and size of the creatures that once inhabited the delta.
Plint said the initial discovery was an accidental byproduct of his work on earth sciences, but it has since become a cornerstone for understanding the regional prehistoric ecology [1].

The discovery of trackways rather than isolated bones provides behavioral data, such as movement patterns and social grouping. By identifying these tracks within an 86-million-year-old delta formation, scientists can map the specific ecological niches and migratory paths used by duck-billed dinosaurs in ancient British Columbia.
