A bit more info on the pic below from Andrew Milner, City Paleontologist and Curator, St. George Dinosaur Discovery Site at Johnson Farm
"This ammonite is over 8 feet in diameter. It was found by my friend Jim Rockwood (that's him on the outcrop) near Williston Lake in north-central British Columbia. It's Late Triassic from the Fernie Group. Same rocks that held that world record Shonisaurus described by the late Elisabeth Nicholls. The ichthyosaur is now housed at the Tyrell Museum of Paleontology in Drumheller, Alberta. both Jim and I were in contact with Paul Johnson (Invert. Paleo. curator at Tyrell). Jim was to show them where it was. Don't know whatever came of that. "
