Would like thoughts on this bone I found in Northern New Mexico, Colfax county, approximately 6,800 ft elevation. Area has lots of remnants of sea shells and marine life. It's concave on one end and convex on the other. I'm also including a photo some of the shell specimens that we're located in the same area. Im always out looking for fossils. I just enjoy exploring and searching for things from the past.Any help would be greatly appreciated.

I am new to fossil collecting and I have a bit of a mystery on my hands, any help would be appreciated. I found this fossil in NJ (USA) in an area well known for late Cretaceous marine fossils (shark teeth etc). I have been told that it is a claw from a ghost shrimp, but I’m struggling to verify that-honestly to my naive eye it looks like a starfish arm. This is an image from my microscope, it is approximately 1 cm in length. thanks!

Wanting an ID please it’s about inch around and found in Sparks Nevada.

Hello found this in California on a job checking to see if they are oysters?

Hi all, Was wondering if anyone has any ideas on this one. I'm thinking maybe some kind of coral or sponge, but I'm not sure. Found in Truth or Consequences, NM. There are quite a few Pennsylvanian marine fossils in the area. It's pretty heavily mineralized, but if you look carefully at the photo with the scale, there are two dark strands running across the center that are segmented. Thanks for any input!

Here are my finds from the Topanga formation today. An Oyster some clams and a lot of Turretella

Can somebody help identify this fossil? Are these vertebrae from a marine mammal? If so, which one? This was found in a quarry in Miocene deposits in southern France. Thanks!

A customer/friend of mine has bought a nice meg tooth and a bivalve from me for his boss for Christmas. He would like to get him a fossil book for a gift now too. He says one that covers marine and land would be good. Something to spark his imagination but also to learn from. He is looking to spend £30 to £40 on it, any pointers would be good please?

Hello, This specimen comes from the Pennsylvanian Period of Allegheny County, PA. It is from the Glenshaw Formation and is probably Brush Creek Limestone. The texture appears to be bone. Thanks for the help.

I found this specimen in Kenosha, WI on the shores of Lake Michigan in 1969 and have never been able to identify it. The backside contains what I believe to be Dichograptidae graptolites. Has anyone ever seen a similar specimen?

Hello! It was found in central Europe on a country road covered with little limestone and dolomite pebbles. Looks like a fossilized mollusc. Is it a scallop? How old can it be? Thank you for any suggestions.

So I'm having trouble identifying this fossil. It's from the bartonian of northern spain. I'm pretty sure it's some sort of brachiopod but I could be wrong. I don't know if any of you could help me with species category too (although I know it would be difficult considering how badly preserved it is)

Found in Florida on Little Gasparilla Island

Hi folks, I haven’t posted in a while, but I still visit and enjoy the forum most weeks. Thanks everyone. Just a curiosity. A find at the end of the day that, made me think….that’s a little odd, is that normal? I don’t know enough. but I know where to ask! Here is half of a vertebra. 2 inches across. At this site it can be anywhere from Cretaceous to Pleistocene marine. New Zealand. we’ve found Miocene and Pliocene cetaceans, seals and penguins. Plus cretaceous plesiosaur and Mosasaur vertebra. There is huge variation in the preservation of bone from these ages. This vert fragment doesn’t seem to fit into what I’ve seen from cetaceans or marine reptiles. But that’s just the bones I’ve seen. It has thick dense cortical bone and much more open cancellous bone than I’m used to for cetacean. But wondered since it’s small if it could be an ontogenetic thing. Thicker cortical bone in juveniles. Anyway just a curiosity and an opportunity me to learn something. Thanks

Hi everyone, Please help identify a few fossils, likely marine life - all found in Central part of Saudi Arabia (location has abundant fossilized coral). thank you! Ps. Ruler is in cm #1

With the surprisingly warm weather early last week, I could not resist heading out for what is likely to be the last hunt of the season. Although I did not have the greatest luck on my last trip, I decided to hit the new Severn spot once again - and I couldn't be happier that I did! Upon arriving I was greeted by the open expanse of weathered marl, reminiscent of the western badlands despite the bustling city only a few miles away. Chunks of orange ironstone stood out against the dark Severn matrix and abundant Exogyra costata oysters littered the ground. The Exogyra often occur in small clusters, presumably what would have been oyster beds at the bottom of the shallow Cretaceous sea. A couple of poorly preserved Exogyra weathering out of the marl. Although I had collected a nice handful of Exogyra on my adventure at the site, I could not resist slipping another into the rucksack . The single Exogyra costata specimen collected on this trip. Although it is only a partial specimen, the bottom valve had a particularly interesting appearance. I wandered across the weathered slopes, keeping my eye out for my vertebrate quarry. Due to the poorly preserved nature of the fossils found at this site, I had an exceptionally difficult time differentiating fossils from suggestively shaped rocks. After the first hour, I had only collected about one piece that I felt was a fossil. Although the vertebrate remains remained elusive, I chanced upon an unexpected fossil - a nice chunk of lignite. The marl was rather rich in lignite, with carbonized remains of ancient plants appearing rather frequently. However, these tended to be highly fragmentary and would disintegrate at the slightest disturbance. A nice chunk of lignite that popped right out of the matrix. The lignite, indicative of a nearshore environment, hints at the exciting possibility of finding the remains of certain terrestrial Mesozoic reptiles in the Severn marls... After finding the chunk of lignite, the finds slowed once again. The misshapen ironstone concretions were certainly making their best bone impressions! . While investigating a cluster of Exogyra, I happened upon my first vertebrate fossil of the trip. A nice-sized shark tooth of a similar size to that recovered on my last trip. Based on responses to my last post, I am unsure if it would be appropriate to label this tooth as Scapanorhynchus sp. Any insight would be appreciated . Following the discovery of the first shark tooth, my eyes quickly began gravitating to the suddenly abundant fossils that littered the ground. It was not long before I had gathered a small sampling of surface-collected Severn shark teeth. A few more shark teeth found shortly after I happened upon the first. Unfortunately, the teeth are very poorly preserved and some smaller, brittle teeth disintegrated under the slightest pressure. A few of the smaller shark teeth. The poor preservation combined with the weathered condition of these teeth renders them almost unrecognizable. The shark tooth haul of the day. Along with the shark teeth, numerous white bone fragments littered the matrix. Although these initial seemed quite similar to the concretions and pebbles that lay alongside them, I gradually began to develop an eye for bone. Like the shark teeth, the bones were coated in a white, crusty covering and many were extremely fragile from constant weathering. A handful of fish vertebrae and some miscellaneous bone fragments. Some chunkosaurus, possibly from marine turtles or mosasaurs. The largest bone fragment of the day. This is likely too fragmentary to be identified, though I would be curious to see if any members have suggestions. A view from the end of the bone. What I have tentatively identified as a fish jaw section, possibly from a fish similar to Enchodus. Another intriguing bone fragment. After having spent several hours at the site, I was far more successful than I had been on the last trip. With my eyes attuned to the preservation of the fossils, I decided to give the place I had started at another try. I happened upon several bone fragments before my eyes landed on the last thing I expected to see weathering out of the steep slope... ...a large mosasaur vertebra! The processes were missing and it was badly weathered, but it was a season-maker. In my excitement, I forgot to take in-situ pictures, though it seemed to be little more than another concretion before I picked it up. The vertebra is quite busted up from being exposed to the elements, though some consolidation should help preserve it. Owing to its poor preservation, I do not know if an identification would be possible. In case there is a chance of ID, my understanding is that the three main species of mosasaur recognized from the Severn are Halisaurus platyspondylus, Mosasaurus condon, and Mosasaurus maximus. The vertebra seems to bear a resemblance to that of M. maximus, though the condition makes it very difficult to tell. Overcoming the initial excitement of the discovery, I had to wonder how many times I had walked over the vertebra... and what else I may have overlooked. Thanks for stopping by and happy hunting!

Found this in a bag of Miocene-Pliocene micro matrix from Aurora Fossil Museum in North Carolina. I apologize for the less than stellar image, but this object is only 2mm long and my microscope cam is at it's limit here. It is hollow. The larger end is circular. The smaller end is obstructed by what looks like a portion of a missing bit at that end. There are no holes in the basket-weave outer texture, so not bryzoan. The surface is somewhat dirty as I was afraid of losing it if I tried to clean it. I can't find any matches in my Miocene library. I don't have much on Pliocene or later. Might also be foram, mollusk, or worm. None of those have cancellated ornament on that shape shell/test. Does this look familiar to anybody?

Hello out there. I am very new to this collecting. Just a little background and how I started this so late in life. I will keep it short as not to bore anyone. My daughter is turning 30 this month. She is so awesome and I wanted to get her something more personal than some snarge off the shelf. She is a marine biologist and marine engineer. I was looking onto getting her something that would go with her passion. So I started looking into a marine fossil of some type. Being completely new I ended up going down a "rabbit hole". Wow it is complicated. So now the question. What do I get a her for a gift? And how do I not get taken on a price or something that is not real? There is so much out there on the old internet and I am sure as a "noobie" I will get scammed. So here I am looking for information / opinions from the pros. I completely understand I am new here. However, I am a real average "Joe" looking only for direction / information. On a side note, after looking around so much on my own I am now looking to start my own collection. JR
