  1. EDIT... never mind I found it... "Kinneyia" and this was the paper. Thanks Folks! original post below.... Blair County, Pennsylvania, USA Hi folks, long time no see. I think the sandstone is from the top of the Keefer subunit at the top of the Clinton Group. Under someone else's post a few years ago, I recall someone giving this pattern's name, and also a discussion whether current thinking is that it is microbial/algal or trace or records a seismic shock. I can't find any of that anymore, and I just can't remember.. Can any of you remind me what this pattern is called? Extra points if you might still have link(s) to papers mentioned in the earlier discussion. Thanks~ PS samples are different rocks, and are both from (or in) the float. The patterned surface is the bedding plane

    Pentameroides subrectus

    From the album: Hamilton, Ontario Fossils

    Pentameroides subrectus (Hall and Clarke, 1892). One of the valves of this mid-Silurian brachiopod. Found at a creek along the Niagara Escarpment in Hamilton, Ontario. Reynales formation, Clinton Group.

    Pentameroides subrectus

    From the album: Hamilton, Ontario Fossils

    Pentameroides subrectus (Hall and Clarke, 1892). Found at the Niagara Escarpment on a creek in Hamilton, Ontario. Reynales formation, Clinton Group. Mid-Silurian. This brachiopod steinkern has specks of pyrite on it.

    Brachiopod? Or USS Enterprise?

    Found near Altoona, Clinton Group, Silurian. Is it a brachiopod? And what are the vibrant yellow and red parts? Is it from mineralization? Thank you.

  21. From USA, Pennsylvania, Blair County...... Silurian Clinton Group. In profile, this looks conical, with the point down in the sediment rather like a conularid. But viewed from above, it is ROUND.
  22. Hello guys, Summer is nearing its end so I decided to go and hunt the Niagara Escarpment of Hamilton, Ontario. The exposures I checked out at a creek ranged from the Cataract Group (early Silurian with the Whirlpool formation at its base and it sharply cuts the Queenston formation) all the way to the Clinton Group. Here is a pic of the Manitoulin formation, which is a part of the Cataract Group and is above the Whirlpool sandstone/formation. Above the Manitoulin formation is the mostly shale dominated Cabot Head formation. The Manitoulin and Cabot Head formations will contain fossils like this rock below. On these rocks one can find many small rugose corals and brachiopods. I move up stream to come across the base of an exposure with much rubble that comes from the Grimsby formation (Cataract Group) all the way to a portion of the Lockport Group. This stretch also covers the Clinton Group. A rock from the Rochester formation. This below is an interesting trace fossil as it reminds me of the Bergaueria trace fossils I used to find in the Georgian Bay formation of Toronto, Ontario. This one below belongs to the Cabot Head formation. If anyone thinks I should have kept this trace fossil, let me know what you think. New material is always falling at the base so it can be a nice ground to hunt for fresh material, even though some Silurian formations in this part of Ontario can be unfossiliferous. The creek ran on trickle since it is summer and made it easy to explore the creek. One of the finds I came across was this slab of pentameriid brachiopods (Pentameroides subrectus?) from the Reynales formation of the Clinton Group. In as much as I wanted to take home the entire slab of steinkerns, I decide to just smash it (as I am limited in space) to keep the more complete valves as finding nice complete valves from this formation is hard to find in my experience. But for real, this slab was also not eroded, had nice detail and would have made a nice display piece have I got the space. I also have the tendency to keep the best specimens I could get my hands on when I go fossil hunting at my locales. Here is a rock I decided to take home from the slab with at least two complete valves of pentameriid brachiopod. Here is one of the valves I took home from smashing the slab. Smashing the rock was hard and bits of it went flying as I tried to smash it up. The Reynales formation is mostly dolomitic limestone and these pentameriid brachiopods I took home also had pyrite on them.
  23. Hello guys, I was out fossil hunting at the Niagara Escarpment of Hamilton, Ontario today and I came across this odd piece of Rochester formation shale (Clinton Group) with a knobby object on it. Could it be anything underneath all that shale or is it just my wishful thinking?? It also got some calcitic bits on the side too.

    Lost River, WV Clinton Group Fossils

    Here are some fossils from Lost River, WV. They were found near the Needmore formation roadside quarry. These fossils are not from the Needmore formation, instead they are from the Clinton Group. The Clinton Group, from what I found during my research, is composed of the Keefer and Rose Hill formations.
  25. Yesterday and today I scouted two waterfalls on the Niagara Escarpment in Hamilton, Ontario. I only intended to check on what the winter has eroded away but I ended up finding some small fossils. The first waterfall I visited was the Devil’s Punchbowl. I only visited the lower falls (the one that runs over the Whirlpool Formation) of the Punchbowl as the creek of the fall has yet to dry up from warm weather. I ended up finding some small brachiopods and an orthocone on the Manitoulin Formation of this fall. Wow, I dont think an orthocone has been reported on the Manitoulin Formation at this locality yet. I might have to go back to those papers. I think this could be a Michelinoceras sp.
