    Rainy Day Hunt

    Last weekend was to be spent with a Fossil Forum friend touring the formations in my area. Unfortunately the weather forecast showed that a rainout was likely resulting in a change of plans. Connor decided to head south to Kentucky. Being “stood up”, I decided to venture out on my own, in spite of the gloomy forecast, in hopes of creating jealousy with my finds. But based on his recent post showing his wonderful finds down in Kentucky, he was the one who made me jealous. Grudgingly, I will show my findings anyways! These were found in the Elgin Member of the Maquoketa, which is Ordovician.
  2. Spent yesterday and today out and about in my area and thought I'd snap a few pics and show. Just as context, my city's rocks are all glacial erratics from the Devonian. I didn't find very much, nor did I expect to. The photos are not of the specimens I brought home (I still need to do that), but some odds and ends from this part of the province. Saturday's location is a largely abandoned sand and gravel quarry, and was one of the last barriers of a massive lake during the last glacial period to finally break and spread till and cobble love all over this part of the p

    New Gastropod for Me

    I stumbled onto this cute tiny gastropod from the Galena/Ordovician in Minnesota but am having difficulty with its identification. Strophostylus textiles is listed as a possiblity in Minnesota Fossils and Fossiliferous Rocks by Robert Sloan. What do you think?? Mike
  4. I've started a gallery of trilobites of Laurentia that are in my collection. Most are from Ontario and Quebec, Canada. I'll also start a gallery of echinoderms from the same units.

    Missouri Fossil

    Images have the sharpness and definition turned up to hopefully see more detail. I wish I could say the formation but the map I was looking at was particularly large and I just couldn't really tell. All I can say is that all of the possible formations were from the ordovician period. The first rock is 2.54 centimeters wide, and the second is 19.05 centimeters wide. I was thinking that it was a coral maybe? The shape reminds me of brain coral, but I also haven't seen any coral fossils like this one so I don't know. Sorry if the photos are bad, I took them on

    Ordovician decalcified...?

    Only for who is familiar with decalcified material. Upper ordovician, Italy. Scale bar 5mm. Decalcified specimen are preserved as the internal and the external mould, so the calcified part occupied the space between the two moulds. On the left side: the two moulds of the first specimen On the right side: only one mould available of another specimen (I guess conspecific), worst preservation. Any idea of what could be?
