|Middle Campanian Plant Fossils / Cranberry Arms|
The fossil caused a stir amongst his construction colleagues but it was nothing compared to the whoops and squeals from local paleo enthusiasts. And rightly so. What do you think of when you envision palm trees? You see warm, tropical beaches, hammocks swaying in the wind, am I right? Most of the fossils found in the Nanaimo Group of Vancouver Island are marine, so a tropical terrestrial site was hot news!
I learned about the site from a very excited paleo colleague calling late one night. He excitedly shared that they'd found a new Late Cretaceous plant site up near Cedar on Vancouver Island. While this is exciting for some, the construction company was not nearly as excited. These were plant fossils after all, and not some new species of dinosaur or ancient hominid. The construction was briefly paused to allow some collecting to take place but was set to continue the following week. They did have a highway to build. Many keen volunteers swooped in to see what could be unearthed. Phone calls were made. Shifts were scheduled. Headlamps were employed as folks took to digging in the dark to maximize the limited collecting window.
Many beautiful specimens were collected. The fossilized leaves, branches and plant remains from broadleaf trees, shrubs, conifers and ferns were immortalized as they slipped into the muds and fine sand of a balmy river environment and slowly buried. 70 million years later, we were doing our best to dig them right back up again.
The fossils included plants and seeds you would expect to find in a much warmer, wetter environment than the climate enjoyed on Vancouver Island today. Perhaps as much as 10° warmer. We see similar specimens of Ensete (banana) and Zamiaceae (cycad) down in Washington State in the Eocene Chuckanut Formation. It is thrilling to see the correlation and transition in both faunal species and environmental conditions for the Pacific Northwest from the Cretaceous to the Eocene. The specimen you see here was generously gifted as a souvenir to attendees of the Third BCPA Symposium in Victoria, British Columbia.
