PALTECHIOCERAS OF WRANGELLIA

Those working in the Jurassic exposures on Vancouver Island are a determined crew. Most of the sedimentary deposits of the Jurassic are exposed in the hard to reach areas between Nootka Sound and Cape Scott. By the time these ammonites were being buried in sediment, Wrangellia, the predominately volcanic terrane that now forms Vancouver Island and the Queen Charlotte Islands, had made its way to the northern mid-laditudes.

This detail of the Jurassic ammonite, Paltechioceras sp. shot with an ultra-low f-stop, is from an all but inaccessible site in Sayward, Bonanza Group, Vancouver Island.
