Dinosaur bone

In July, I found a dinosaur bone in Dinosaur Provincial Park! It was lying in a wash coming off a small mesa, and sure enough, when the students and I walked up the little draw, we came to in situ bones poking out of the cliff above. After showing it to the students, I put it back down exactly where I had found it, of course.

Friday fold: Warspite Anticline

A final guest Friday fold from reader Howard Allen, who I’m pleased to be meeting up with in Banff late next week… Howard writes the following in describing this lovely scene: Warspite Anticline, Peter Lougheed Provincial Park, Alberta. Photo is a telephoto shot (hence the strong blue alpine haze–the colour cast is an accurate rendition of the original daylight Kodachrome slide), looking southwest at an angle to regional strike. The …

Fossil clams at Devil’s Coulee, Alberta

At the eroded gully known as Devil’s Coulee in Alberta, you can find armored mudballs, dinosaur fossils (including eggshell), and even marine clams at higher levels in the sequence. Check out these lovely beasts: They lived and died on the western shore of the Western Interior Seaway during the Cretaceous period of geologic time. My Canadian Rockies field geology students visited this site in 2012. I’m taking students back again …
