WEB EXTRA: Understanding past helps us understand present

The geology of Vancouver Island is made up with mainly igneous volcanic rock from an ancient ocean that was overlaid with sedimentary rock, then more volcanism and more sedimentation well out in the South Pacific.

This massive volcanic base slowly moved from the equatorial area and then crashed against the west coast of North America about 100 million years ago.

Along the margin of this ancient sea, sedimentary rocks such as shale, sandstones and limestone were laid down over 300 million years. Within these sedimentary rocks are well-preserved fossils from many different time periods.

From Vancouver Island’s oldest fossil trilobites found near Port Alberni, to the Permian crinoids of Marble meadows, to the Triassic Ichthyosaur of Holberg, to the Jurassic, Cretaceous, Eocene and to the recent time.

Understanding the history of ancient life in the ocean and on the land and the many changes over the years can help us understand events that are occurring in today’s world.

Dan Bowen, chair of the Vancouver Island Paleontological Society (VIPS) will present a fossil history of Vancouver Island this Sunday (Feb. 23) at the Courtenay and District Museum and Paleontological Centre at 1:30 p.m.

Following the presentation, VIPS members will renew memberships and welcome new members at the AGM.
