  1. 3D Printed Fossil Replicas Reveal Lifestyle Of Ancient Cephalopods by David Bressan, Forbes Magazine, July 18, 2021 The paper is: Peterman DJ, and Ritterbush KA. 2021. Vertical escape tactics and movement potential of orthoconic cephalopods. PeerJ 9:e11797 Yours, Paul H.
  2. I took a walk along Etobicoke Creek on the weekend and found some of the usual suspects!

    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
  6. 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?
  7. As some might have read in a previous topic, I went to visit my girlfriend in Finland. Unfortunatly Finland must be one of the worst places to find fossils in the world, I did manage to find some quartz vains and a few pieces that may or may not be amber (have to do the hot needle test on them first) Even urban fossil hunting is near impossible as pretty much all buildings are made from the fossil-lacking stones that can be found in Finland. The only urban fossils I found was in the Burger King in the Helsinki Central Station, the floor was littered with orthocones there. But Finlan
  8. The first major event to wash the creek was the nasty February winter we had in the city. Let's recall the ice that melted and went down the creek back in March. Then fast forward to June. I believe the city had rain during the first 2 straight weeks of June in which I remember seeing many creeks being flooded continuously for several days. Then gradually the rain stopped, I waited for some time to give the creek's water level to drop low again, and that's when I set off to visit the ravines of Mimico Creek.
  9. Each summer I collect near Newberry in the U.P. of michigan from a degrading hillside. I usually find nodules containing graptolites, various "shell" type impressions from brachipods, and trilobite impressions. Generally the nodules I crack open are not more than 3 " . This summer, a large piece of shale was sticking out of the bank, so I dug it out and split it. It had several orthocone fossils and impressions, ( though I don't know what kind) and was filled with impressions of little cone like images. That is a dime for reference, and you should be able to clearly see the cone impressions, a

    Actinocerid Perhaps?

    I spotted this flat orthocone on a platform of limestone at a park beside the Lake Ontario. The limestone on which the fossil is set on was hauled in from Manitoba (from what I heard) and is used in many created and developed parks here in Toronto. I also heard that this limestone is Ordovician, which is kinda true judging from the fossils that I've observed on the rocks (ex. Isotelus fragements, some Ordovician strophomenids, some Favosites corals, only straight-shelled orthocones). Could it be an actinocerid and could these limestones be the ones that originate from the Tyndall limestone?

    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.

  12. Hello everyone! At around at the end of August I started making frequent visits to Mimico creek in order to collect fossils before the next winter comes (hopefully it wouldn't be as cold like the previous one was), and also the other reason was because of the developments going on at the creek. I was fearing that they would eventually cover up all the exposures I know of. I made my way through the woods and shrubby areas to reach certain exposures.
  13. So i recently made my fossil display look a bit nicer, and here´s the result, i took inspiration from some of the displays here on the forum (even if mine isn´t nearly as good or creative as some i have seen here), anyways, here it is: Also, the text in it is all in Swedish, which is pretty obvious considering i live in Sweden. So here´s an exterior view: Atop of it sits a cast of a Nedoceratops skull, i don´t think i have seen many casts of this species (for some reason, the "casters" decided to be a little artistic and made the 2 holes in the frill into 4 holes, i still wonder why):

    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 fo
