From the album: Nautiloid’s Trilobite Collection
This nice little bug is from the Upper Ordovician Liberty Hall Shale of Virginia. It exhibits pretty good preservation considering its size. Purchased from a good friend.© Owen Yonkin 2022

Here are some of the fossils I acquired in a shale roadcut I was told about thanks to @prem. These are ordovician in age, and I have to say it was difficult to collect them due to the fragility of the surrounding material. Ive identified most of my finds, however there were these unusual pill like outlines I wasn't familar with.

Can anyone tell me if these are actual fossils or just geological formations, although they look like fossilize plants to me, it would be very surprising to find fossilized plants from the late Ordovician period. both rocks were found in the Nicolet River Formation on the banks of the Richelieu river

Some recent Upper Ordovician finds at Mimico Creek, Toronto
Rogue Embryo posted a topic in Fossil Hunting Trips
First, if anyone in the Toronto area is interested in going fossil hunting along Mimico or Etobicoke Creeks, I'd welcome the company! Before I get to a couple of better finds, I'm curious to know what the black fragments are below, which I often find embedded in the shale. Can someone please give me a clue about these? Some orthoconic cephalopods: The next two are the same fossil from different perspectives: Some bivalves: Bryozoans: Cheers, Camille

This past weekend I had to cancel a collecting trip due to ominous weather, so I instead made an impromptu trip to northern Kentucky to do some Ordovician collecting for a couple days. I really love this area and would spend a week down there if I could. This trip I decided to focus on the Kope and Fairview formations, two of the older formations in the greater Cincinnati area. The first day was mostly driving and not much collecting due to rain. But I did briefly stop at a spot where I found a pocket of Ectenocrinus crinoids on my last trip. I checked to see if any more had weathered out and found a few small calyxes. I also collected a neat trace fossil and a small brachiopod plate (Zygospira modesta maybe?).

Hey folks. It hit 104 degrees here in Austin yesterday and I have decided to stay in and work on my recent finds in Oklahoma. I have a bunch of Bromide Formation, Simpson Group, Blackriverian (Upper Ordovician) brachiopods that need sorting out. I have Mark McKinzie's book and a few OKGS publications but was wondering if anyone can suggest a "good" reference for sorting them out? In fact this could include references on other inverts from that formation and age. Thanks in advance...

Echinoderm identification help please! Polished cross-section in the Kimmswick Limestone (Late Ordovician: Katian; Missouri, USA) used as facing stone at Missouri Botanical Garden. Possibly the paracrinoid Implicaticystis (once known as Comarocystites)? Specimen is ~25 mm across.

Just wanted to say a quick “hello” and apologize that it’s taken me this long to join TFF! I’m a long-time lurker and frequently use this site to research potential IDs. I live in the heart of Cincinnati, Ohio, so am very fortunate to be surrounded by some of the nicest Ordovician invertebrate fossils around. I frequently (obsessively?) hunt, and am proud to say that my collection is all self-collected. Thank you in advance for your expertise and knowledge—maybe I’ll see some of you around!

Selling Real for Fake Fossils?
Lucid_Bot posted a topic in Is It Real? How to Recognize Fossil Fabrications
Everyone I've encountered on this site has been very helpful, so thank you. However, I'm in need of more help. For the last year I've been collecting real fossils in the field and selling some to pay for more exotic rocks. In a recent post I found that my Solnhofen shrimp is, if not totally, mostly fake. Now I'm quite suspicious of my entire purchased collection and was hoping you could help me identify fakes. The first two pictures are apparently Priscacara, Green River Formation, Eocene; the next two supposedly Asteroidea, Morocco, Ordovician; the last three supposedly Triassic, Arizona petrified wood--this came from the same group that sold me the fake shrimp. All help is appreciated.
