  1. I recently acquired a Daedalocrinus bellevillensis crinoid fossil plate from the Bobcaygeon formation of Brechin, Ontario. At the bottom of the plate is what appears to be an annelid worm fossil. It is segmented but the segmentation is nothing like the segmentation of any crinoid stems I have seen and is more similar in appearance to a modern earthworm; it also terminates with a point. It also has occurred to me that this might be a frond from a crinoid but I don't know what the terminations look like. Would anyone have any suggestions as to how I might identify this fossil? The picture doesn't do justice to it but the item of interest is the item crossing the crinoid stem. Any suggestions would be appreciated.

  10. Mystery Ontario crinoid

    I've posted this on FB, but a certain expert is rarely on there. This was the crinoid I found a few weeks ago that had everyone stumped at the time. Now, after my preliminary prep and then an hour or so of Malcolm's magic, none of us are any the wiser as to what it is. It's from Ontario's Ordovician Bobcaygeon formation and doesn't match anything in the local reference book. It seems as though the plates at the bottom are fairly distinctive so does anyone have any clue as to a possible identification????
  11. First Ebay Acquisition

    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.
  12. A Little extra Baggage

    Sometimes you get a very pleasant surprise when you get your finds home and start prepping. I was very fortunate to find two relatively complete Amecystis laevis this Saturday October 31, 2015 up at the JD Quarry near Lake Simcoe, Ontario , Canada. They most likely came out of the very top part of the BobCaygeon formation as they were both found in a recently created pile and not in situ. If not it was from the very bottom of the Verulam This picture because of the lighting used came out a bit blue. I am not the best photographer around. The specimen is on an 85mm * 66mm matrix and is 79 mm long from tip of arm to tip of tail (about 3.1 inches) . The theca on the amecystis is 17mm wide by 22 mm long. The Amecystis is a dorsal orientation. The edrio is approximately 6 mm in diameter. I believe this to be a Amecytis laevis (Raymond) by the way Thanks for the correction Kevin (Northern Sharks) there are definitely no pore rhombohedrons on this specimen. It is a shame that the Amecystis and the edrio both have some slight damage to them from the quarry blasting. But they are still very good specimens. The amecystis is fairly well inflated and nicely colored. Here is a better picture showing the true coloring. But to my surprise it has a very nice attached travelling companion in a edrioasteroid which I believe to be an Isorophusella incondita. What makes this super interesting and probably quite rare is the fact that the edrio is attached to the amecystis and may well have been there when the amecystis was alive. I wonder if anyone else has ever come across this particular association. Edrios are often found attached to brachiopods in this locality. This was prepped using 40 micron dolomite under a zoom scope at 22 PSI using a Comco .018 high precision nozzle on a Comco air abrasion unit.
  13. Just A Little Ring

    Just a quick post because this is somewhat of a rarity. About three weeks ago I was hunting fossils in my favorite Ordovician location up here in Ontario Canada with a few friends including Northern Sharks and I found my first ever cyclocystoid. I cannot tell you how many 1000s of crinoid stems I have thought for a split second might be a cyclocystoid or edrioastroid. Finally picked up the real thing...... not an imposter. The segmentation in the ring is the giveaway. This one is in quite a good state of preservation and has had an initial prep under the scope with air abrasion. (40 micron dolomite 22 PSI and .018 nozzle). I may still clean up the center a bit more at a lower PSI and use finer abrasive (22 micron and a smaller nozzle .010) . The fossil is 14mm across. I have not seen one of these found at that locality in person but am aware of two other specimens. One of the other specimens was slightly smaller than this one. A very experienced collector at that site indicated that this was one of the rarest fossils to come out of that location. I am quite pleased with it and it will become part of my personal collection as this is a new species for me at that location.
