Last fall after working a museum, I returned to a ranch in the Pierre Shale south of Rapid City. One of the students I'd brought with me earlier in the spring of 2016 spotted a chunk of fossil that we originally identified as wood, before we realized that it was a large squid pen! So, right before our classes started we got back together and spent a few days camping on the ranch to excavate it to donate to the museum as well as some other fossil. All kinds of things got in the way, our car broke down, we were driven out of our tents by a thunderstorm, and if it weren't for GPS we would have lost the location of the pen. The site was on a steep, soft hill of shale on the edge of a ravine with a half dozen cattle skeletons from a blizzard back in the nineties. But we got the squid out of the hill and into the museum! Almost a meter long, seems to be the middle of the rachis with a few fragments of the vane

Hello. I found this "thing" on the ocean floor while diving in the Philippines. It looks kind of like a tooth of a marine animal, probably not a shark. Any ideas?

Hi all, I just acquired this interesting specimen that was identified by the seller as Helicodromites mobilis. However, when trying to verify this, the images and description I've been able to find really don't seem to match. The whorls on this are flat and attached to the core. To me, it looks more like a cast of a shark egg case. Are any of you familiar with H. mobilis? Thoughts? Thanks for taking a look!

Ok so I'm brand new here and I'm hoping you guys can help me out. I found this what I think is a fossilized bone (maybe skull) fragment washed up on the beach at westmoreland state park in montross virginia along the potomac river. The area, I believe, is part of the calvert cliffs along the chesapeake and therefore should be from the Miocene. I've been trying for months to figure out what this thing is and the best idea I have come up with is maybe a skull fragment from a miocene dolphin of some kind but I'm honestly not completely sure it's not just a rock. I may have gone overboard with the pictures but I wanted to make sure you guys had the best possible understanding of what this thing looks like. Its about 5cms at its widest point. Thanks for taking a look.

This coprolite is from a marine creature that swam in the Jurassic seas that once covered this parts of England. The dark inclusions that can be seen on the surface are Onychites (cephalopod hooks). In April 2016, the University of Minnesota X-ray Computed Tomography Lab scanned the specimen using a X5000 high resolution microCT system with a twin head 225 kV x-ray source and a Dexela area detector (3073 x 3889 pixels). Many of the images shown here are of individual 3D elements/features within the coprolite that were separated/isolated using Blob3D. The taxonomic classification given is for the inclusions, not the coprolite. Aside from the hooks, it is hard to definitively identify the inclusions without damage to the coprolite. The following is a list of inclusions: 241 hooks of various sizes that are at least 75% intact. 200+ plate-like fragments of various sizes (likely similar to the surface nacre). 19 ellipsoidal structures, possibly forams or parasite eggs. 2 unidentified long, straight conical structures joined at wide end (A) 1 long rod-like structure with a bulbous end (B) 1 unidentified mass that looks like it was the attachment point for 5 rod-like structures (C) 1 1ong cylindrical (rod) structure that tapers in the center. The center density is much lower than the outer shell (D) 1 irregular structure that looks I originally thought might be an ink sack or buccal mass, but the size is wrong. Experta think it is more likely foraminifera (E) 1 irregular structure, possibly a statolith (F) Acknowledgements: Thank you to Neale Monks and Christian Klug for providing input.

I found this recently in an Early Mississippian lag deposit amongst several other fossils, including shark's teeth, bones of unidentified critters, and phosphatized inverts. From my observations, I believe that the site represents an estuarine setting. I don't find any plant material here, but that doesn't mean that terrestrial critters might not show up. I have my own opinions about the piece, but let me know what you think! Early Mississippian Cumberland Plateau Size: approximately 1cm across

This conical, segmented, fossil was picked up off the shores of Lake Ontario in rocks that contain a lot of bryozoan and crinoid fragments. I think it is Devonian, but could someone help me confirm that, and help me understand what this fossil might be?

I found this yesterday at Lost Creek dam, Finis Shale member of the Graham Formation. The darker parts might be shark cartilage. Any ideas?

Dear All, I found this in Tuscany 2 days ago, being used as a hearth stone for a fire in a field. Given its Tuscany and its odd shape I guess its marine. Please excuse the poor attempt at dyeing it. Very grateful if anyone has a clue what it is, I have looked at a number of sites and drawn a blank. Its approximately 7 cms wide at the base and 7.5 cms tall. Many thanks, Miles.

Hello everyone, I found this fossil while combing the beach the other day. I am trying to figure out what it could be. At first I thought whale, but it seems small for a whale bone.

This was found in a dry riverbed north northwest San Antonio Texas. It's obvious marine but I haven't been able to ID Please help

This might prove very easy for more advanced fossil collectors to answer. In 2004, the floodwaters from Hurricane Gaston swept away a large amount of soil and clay from an existing stream near the backyard of our suburban house near Mechanicsville, Virginia, exposing a clay bed littered with numerous fossils. The turritella you see in the picture occurs the most frequently of all our finds, and the small clam fossils are a close second. We've recently started to find more of the kind of scallop fossil in the image, which we guessed was a chesapecten jeffersonius, Virginia's state fossil. I found one moonsnail fossil in the same clay, but it's the only fossil of that kind that we've found. Anyway, I'm not much of a geologist, so I haven't been able to precisely date these, or identify them with a specific epoch. I have what I think is a reasonable guess, but I'd like to get a specific date on just how many years worth of soil Gaston scrubbed away from our backyard. Thanks!

Hi all A friend found this on a beach in South Africa. Is it possible to ID to species or genus level? Many thanks

Had a blast last weekend visiting The Virginia Aquarium & Marine Science Center. There is a ton of stuff there that's really worth checking out and I noticed an assortment of fossils. The first picture is a crinoid head.

My kid and I headed north to see my family and friends in Cincinnati over TG weekend. And as they all have come to expect, I have a habit of slipping away at some point each trip to conduct sorties and surgical strikes on various fossiliferous exposures. This time, I was able to talk my friend Joe into getting up early and coming with me. Joe and I have been through a lot over the years. We've been friends since I let him cheat off my homework in 3rd grade, circa 1978. I stepped in a few times when kids tried to mess with him in grade school. We conspired to torment substitute teachers together. We've served as best man for each other over the years, and I was a pallbearer at his dad's funeral. The decades have a way of binding buddies together through thick and thin. In that spirit, I endeavored to take Joe to a slam dunk site, help him get acclimated to the presentation of fossils, and then turn him loose on the sweetest stretch of the exposure. So at 5 a.m. I kicked his door in and whisked him off to the Mississippian aged Indian Creek Shale of southern Indiana a little west of Louisville. With a bit of a car ride ahead of us, we had fun recounting the various misdeeds of our misspent youth, throwing around horribly inappropriate humor, and somehow, in the end, solving the world's problems. OK, we are there now. Time to grab some tools and start climbing.

Upon digging a large hole for a pond in Suffolk, Virginia, we came across lots of shells and other Oceanic remains. We've even found a few shark teeth. This little fragment is one of the more unique items we've found so far. We're assuming it's some kind of skull, but I'm not sure. I came here in the hopes someone would recognize what it's from. If the crescent shape formed a complete circle, it would be about the size of a fifty cent coin. I will attach a few photos. A couple of the photos include some other items found in the same pit (crab claw, shells, etc). Thanks in advance for any assistance!
