Breaking the KT boundary on Vancouver Island
Neanderthal Shaman posted a topic in Fossil Hunting Trips
Being from Washington State, almost all of our fossils are Cenozic. The oldest fossils I've ever personally collected from here are Oligocene, and the oldest fossils I've collected overall are Eocene (Green River Formation)! My dad and I took a a couple days to camp on Vancouver Island, and I couldn't resist going to the Trent River to finally break that KT boundary. Here it is! The first Mesozoic fossil I've ever personally collected. A couple of small Mytiloides clams. These were abundant at an outcrop halfway to the falls. During our first trip to the river, I nabbed a concretion. The next morning at our camp I gave it a wack with the ball-peen hammer. At first I thought it was a coprolite, but I'm pretty sure that this is a crab carapace. Note that there's a ridge right down the middle, and it's largely symmetrical on both sides. I had to do a bit of work with the Dremel to expose more of the left side, but nicked it quite a few times. My solution was just to douse it in Paraloid to make the damage less noticeable. If you think it looks excessively shiny now, you should have seen it before I wiped it off with acetone. I did some research on crabs from the Haslam formation and Eucorystes platys seems to be a good match, it has that ridge down the middle.- 27 replies

This crab along with another of the same type are currently with Torrey Nyborg of Loma Linda University in California. I'm told they are Paradoxicarcinus sp. (possibly P. nimonoides or maybe something new). At any rate Torrey Nyborg expressed interest in examining and describing them because he felt they may be something new. If they are indeed new and/or are published they will be donated to the Royal British Columbia Museum, in my hometown of Victoria (BC), not far from where these and other crab fossils were found).

Crab fossil from southern Vancouver Island
palaeopix posted a topic in Partners in Paleontology - Member Contributions to Science
This specimen of a possibly new crab (galatheoid? or homolodromid?) from southern Vancouver Island has been sent, for study and description, to Torrey Nyborg at Loma Linda University in California. The specimen is to be donated to the Royal British Columbia Museum in Victoria, BC. I will update the forum once I've heard back from Torrey on the status of the specimen. Torrey has also expressed interest in a number of other decapod crustaceans collected in association with this specimen. So those fossils may eventually make their way (two already have) to him for description and potential donation to the RBCM.- 2 replies

Only one like it (with ribs this prominent) from this site. See also the less ribby specimen I have posted, which I am less certain is a Canadoceras, but is more common at this site.
