Interesting shell found at Douglas Point, Maryland which should be Paleocene Aquia Formation. Didn't see an obvious match anywhere online, any ideas?

Yesterday I finally made it out to one of my favorite hunting spots after (almost exactly) a year away. This road cut in La Salle County Illinois had been visited earlier this year (I believe) by @Nimravis, @aek and @connorp, but I really wanted a crack at it before summer fully kicked in. As I had been warned, it was already heavily overgrown, with poison ivy located intermittently across the slope. There were also mosquitoes in the shady areas and wasps in the sunny ones. However, with some delicate maneuvering I was able to avoid most of the hazards, with only some mosquito bites to show for it. I was at the site from 11:30 to 5:30 and the sun shone bright nearly the entire time, although thankfully an occasional breeze kicked up and cooled things off. Here is a sequence of the path up to the head wall, as you can see it quite brushy at the base of the cut. All in all, I would call it a successful day. I was able to find quite a few interesting mollusks, both gastropod, cephalopod, and bivalve, that I had not encountered before from this site, and a few trilobite bits as well. The real reason I keep coming back to this location, however, is the high-quality and diverse chondrichthyan fauna found here, and it did not disappoint. In addition to many tiny shark bits which may or may not prove to be worth prepping, I found a few larger specimens which I am hoping are all or mostly complete. The trip-maker was this beautiful Deltoptychius: I also shared the site for part of the afternoon with @TheSandStorm, who was making his first visit to the locale- it was a pleasure meeting him. I love seeing new folks getting out to explore and discover the wonders of the fossil world! I will share more pictures of my finds in the next post.

Found this lovely pair of bivalves in Mimico Creek over the weekend and hoping to get some help on ID. It looks like either Colpomya or Cymatonota, based on images I've seen. Any ideas in this? Camille

Hi everybody! I've been in the process of trying to identify the types of mollusks I found on a recent scouting trip out to the Lincoln Creek Formation. I very much don't know what I'm doing regarding identification or preserving, so any tips will help! Regarding the bivalve, I'm wondering what I can tell with the ligaments. I feel I can safely say it's a taxodont, but I don't know where to go from there. I think that this fossil shows the imprint of the inside of the shell, and I think that the outside is well ribbed, but I think that from impressions left near this fossil from presumably other bivalves of the same species. (Is that a muscle scar I see in the outside photo?) I also got a couple gastropods from the trip, but don't really know anything about those, either. I'm brand new at this fossil hunting/id thing, and am really interested in learning how I can date a formation by the fossils, etc...

Hi, I have come across a few different bivalves and my googling hasn't come up with much! I think the heavily prepped one that has no matrix might be Dacryomya Ovum? Not sure though as this is from a single image in google! Also any idea what the little babies in the back of the matrix might be? They all came from the same man who picks and preps Whitby stuff himself so pretty sure that is where they are all from. Thank you and fingers crossed! 1

Brought my son out to my new secret spot in Contra Costa County, SF East Bay Area, CA (thankfully NOT within any park boundaries). The spot is a deep creek bed around a border where Eocene (Tdu/Domingene form.) and Early Cretaceous (Kbs) meet. There are lots of nice gastropod fossils in large masses of sandstone, a few brachiopods here and there, but my favorites are the many quite large bivalve fossils and whole oyster fossils we found. Today my son spotted a really nice cluster of large bivalves peaking out the wall of the creek bed, and he found another whole oyster! He was so thrilled.
