  1. I found this buried in the water in Joshua’s Creek, Oakville. This giant rock containing many coral fossils and a couple of Orthocone fossils also. I’m certain the fossils are Ordovician in age. Measurements are 30cm in length and 19cm in width. Can anyone help with identifying the Orthocones and Corals down to species pls? This is my biggest find yet, so excited to hear everyone’s opinions!

    Common Misidentifications

    Howdy all. I'm one of those that value correct id's when it comes to fossils, so I thought that I'd post some common misidentifications often seen in anything from gift shops to proffessional collections. If you know any other misidentifications you are welcome to post them here First up are the "Orthoceras" slabs coming out of Morocco (all these misidentifications are of moroccan fossils). Orthoceras currently only contains 1 species, which is only known from my general area (Northern Europe), based on my research, the species originally called "Orthoceras fluminese" is the correct ID for the moroccan orthocones, and this species is today known as "Orthocycloceras fluminese". Second, another paleozoic invertebrate, the Moroccan calymenids are very common and are often labelled as "Calymene" or "Diacalymene", but neither genus exist in Morocco. The correct species for these trilobites is "Flexicalymene ouzregui". Third, we have the Moroccan Globidens teeth, these are often sold as "Globidens aegypticus", a species that according to both Wikipedia and the Paleobiology Database doesn't exist. The name you're looking for is "Globidens phosphaticus". Lastly, we have another mosasaur. "Mosasaurus anceps" or "Prognathodon anceps" teeth are quite common on the market, but they do in fact belong to "Liodon anceps", sometimes teeth labelled as "Prognathodon sp." Will belong to Liodon as well. I hope this helped

    Treptoceras crebiseptum orthocones

    From the album: Urban Fossils of Toronto (Georgian Bay Formation, Lower Member)

    Treptoceras crebiseptum specimens. The one on the left comes from Mimico creek. The blue grey one on the right is covered with bryozoans and comes from the Humber river area and is complete is actually missing the living chamber. Both belong to the Georgian Bay Formation.

    Complete Treptoceras crebiseptum

    From the album: Urban Fossils of Toronto (Georgian Bay Formation, Lower Member)

    Complete specimen of a late Ordovician cephalopod Treptoceras crebiseptum, even with the living chamber intact. The length is appr. 37 cm. From the Mimico creek, Georgian Bay formation, Ontario. Specimen found in shale and my first complete one!! I usually find small fragments of the phragmocone at Mimico creek. Also keep in mind specimens found in shale are preserved squashed, compared to the ones preserved in limestone they are preserved in their original shape.

    Praire du chein group i.d.

    Once again this summer I was able to do a bit of fossil hunting on the edge of a quarry between Shawano, WI and Green Bay. I believe it is Praire du chein, but it could possible be St Peter. At any rate, these three fossils were all found in the same stone, which i believe is dolomite, from approximately 50 feet lower than the surface. (Though not this stone, I found another nearby, that was dolomite with a 2"thick layer of what I would call mudstone, easily broken off in sheets...it contained small as well as small braciapods..a really interesting stone...I had my loop with me, and so looked through the material as i flaked it off the hard dolomite underneath...talk about an intriguing hour. It was really cool to see all the bits and pieces that were in that mudstone. But I didn't have my camera along, so have no photos, only my memory) Getting back to the I,D.s I am curious as to what the deep curled creature might be, and if anyone can tell, or suggest the name of an orthocone for the other two images...They were all on the sides of a boulder easily weighing 1000 pounds. Thanks for any suggestions. Just curious because I hunt in that area alot. BTW...often it is stated that northern wisconsin doesn't have any fossils...that is simply untrue....granted many are ot found on the surface having been scraped away by the glaciers, but there are plenty in the bedrock if one has an opportunity to explore a quarry, as I was able to do..
  7. So many orthocones in Etobicoke creek I couldn't carry them home. Some examples attached. But what is that little 1cm grey doo-hickey with 2 convex lobes?

    Take 2 of the Modiolopsis slab

    From the album: Urban Fossils of Toronto (Georgian Bay Formation, Lower Member)

    A second and more detailed photo of the modiolopsis slab. This one shows a little bit more detail, hopefully. Also, it appears that this thing is not full of modiolopsis as I first concluded, but rather it is full of Whiteavesia pholadiformis. There is also a Cymatonota lenoir, and it appears to me that there is only one specimen of modiolopsis, which would be M. concentrica. Dime shown for scale, and Georgian Bay formation, Mimico creek.
