Its been a long time since Ive posted any find on here, so I thought Id show some of what I collected during this past winter. I took a trip to the Silurian of Tennessee to collect with a friend and did pretty good. This was my first time collecting Silurian fossils. These are from the Brownsport Group. I'll start with the sponges Astraeospongia meniscus a fairly common sponge, I collected several. Next up is a neat little Brachiopod. Machaeraria sp. And now enchinoderms. Calyx of the crinoid Lampterocrinus tennesseensis Another first for me...a cystoid! Caryocrinites ornatus and another! A nice blastoid - Troosticrinus reinwardi Heres a shot showing the complete ones I found. The two large objects on the top left are sponges. The items with the branches may be bryozoans (one has a stem wrapped around it.) The crinoid cups to the right are Parapisocrinus sp. And the item by the penny is a tiny Leptaena sp. brachiopod (another first!) And now for my sole arthropod find. The surface is very rough, but it seems there is a mold under that. I may try to uncover it. The pygidium is folded down ninety degrees to the rest of it. Not sure as to id at this point. But it seems to be mostly there. I forgot to photograph the corals I found on this trip so I will add those this weekend. About a month ago I found myself very early for work so I decided to stop at the Pennington formation ( Upper Mississippian) for a quick hunt. I didnt keep much but I did snag this partial Deltodus affinis tooth. Thats all for now, thanks for looking.
I was very happy to have my first ebay bid won and this plate was what I got. I've always wanted some fossils from the Lake Simcoe area but I never had the capacity to travel outside that far out of Toronto. Apparently there are two types of cystoids on this plate. This plate comes from the Upper Bobcaygeon formation, Ordovician period from Simcoe County, Ontario. It's a very different fauna from what can be found here in the bedrock of Toronto. Cystoids don't occur in the Georgian Bay formation. Paying for this plate took a bit of a hit on my wallet but I think I think it's worth it considering that I don't have anything like this in my collection.
