These are two fossils of the same species collected at the Long Pond Road Site along the Erie Canal in Greece, New York. They are from the middle Silurian Rochester shale. These were collected last winter, and I have since been unable to identify them. Both are no greater than 3cm in length. Some interesting fine detail is visible on the first specimen. The American dime is 1.8cm in diameter.

Triassic Bivalve Imprint from the Triassic Basin NC (~230 Ma)
AlexSciChannel posted a topic in Member Collections
Here is a picture of a Bivalve imprint I found whilst in a Creek in Western Wake County. I was in the Triassic Basin and they have fossils dating back around 230 Ma ± 2 ma. It was part of the Carnian Stage of the Triassic part of the bigger Newark Supergroup. I presume it is a freshwater genus but I don't hear much about freshwater Bivalves when it comes to Triassic fossils. -

Heteromorphic Ammonite - Is it real?
Wei Yang Low posted a topic in Is It Real? How to Recognize Fossil Fabrications
Dear all, Recently I purchased a "Nostoceras Malagasyense" Heteromorphic Ammonite from an online platform. Initially, I didn't question the authenticity of the specimen, as the seller seems to have quite a few Cleoniceras ammonites for sale (which are clearly genuine). However for this piece I'm quite unsure if it is truly authentic, and would like a second opinion. I understand that there is an Export Ban for fossils from China, but to my understanding that's for Vertebrate fossils (ammonites are invertebrates). My main concerns are: Is it a legitimate fossil? Some parts look carved, but at the same time some of the striations look too difficult/ not worth the effort to forge for the price paid. Thank you! -

I found these fragments of something crabby on my last trip to the North Sulphur River in Texas. They were partially exposed in one of the red bed layers of the Ozan Formation, and were so delicate that they started to crumble when I extracted them. I saved the more whole and identifiable pieces. They're a kind of muddy yellow color, with maybe some hints of the original pigmentation in the blue areas. The red beds tend to either turn fossils black (when they're phosphatized) or a dusty red, so this was quite an unusual find for me. The closest to an ID I've been able to get so far is some sort of lobster like an Enoploclytia, but other than that I'm unsure. Any help with an ID would be appreciated, as would any advice as to how I should go about preserving the fossils to make them more durable, as they are still extremely fragile.

Lots of rocks with tiny fossils. This was on one of these rocks. Most of the fossils are Crinoids but this looks like something else Any ideas?

Hey again, this is a very tiny ~.5cm shell that I found some time ago at the regular road cut at the Lost River exposure of the Mahantango Formation. I would guess it’s a Gastropod or something similar but if it could be narrowed down any further I would be elated. Thanks guys!

Hey everyone just wanted to check in with you all and see how you are doing. I also wanted to inquire about these Worm Borings/Concretions, and what our members consensus might be. Maybe our resident concretion collector @Ruger9a would be able to help me out. Anyway, here are the pictures: Here is a photo of the excavation site:

Hello, I'm looking for an ID on a relatively well preserved marine fossil found in a south florida gravel bed with many bivalve and brachiopod fossils nearby. Any help would be much appreciated. Thanks in advance.
