Hello all! I made my first trip to the famous Eocene Texas location a few weeks ago and have a few things that remain a mystery to me. I have perused the forum and was able to ID most of my finds from jkfoam's informative replies and many topics from other members. However, several of the gastropods below resemble species I have already identified, but they're not quite the same, so I'm unsure exactly what they are. Not all the images have a scale, but they are all micro fossils under half a centimeter in length. Thank you in advance for any help you can offer! (1) I know this is an ootolith, but I cannot differentiate between the two most common kinds. Help would be appreciated, especially as I only have two of these guys and they are the same. (2) Initially I believed this to be an ootolith as well, but after cleaning it, I really have no idea. Image is front & back. (3) Here is another that I believed to be an ootolith but now have doubts about. Image is front & back. (4) This appears very crab-esque to me, but again, I have no idea. (5) Could this be Bolis enterogramma? I can't find enough images on the web to say I am confident with my ID on this one. (6) I have this (and many others) down as Polinices sp., however I cannot tell the difference between these and Neverita sp. so the ID could be incorrect. Could someone clarify the differences for me? (7) Mystery gastropod (two views; same specimen). (8) Another similar mystery gastropod (two views; same specimen). (9) This is one that looks similar to some I've already IDed, but just different enough to make me believe it is something else. (10) I believe these two are the same species, but when they get this small (some of my smallest; only a few millimeters long), I find it difficult to tell. For all I know, these could be ice cream cones.

Hello Fossil Forum! My favorite way to learn anything is to join forum's such as this one, right up my alley and scratch that itch to get out a dig rocks. I grew up in Western NY and learned to dig fossils in the Hamilton Group/Devonian age. I was super spoiled to live close to such beautiful fossils, turned many a friend onto this hobby as well. Phacops and horn coral, gastropods, crynoid stems - I was hooked. Fast forward to now, and I'm a father to Washingtonians. The Eocene is the land out here and I am trying my best to learn where and what to look for since I've restarted my fossil hunting hobby. Most people have no clue where to look hence the reason to join you fine people. Thank you for letting me join. Jim

My son and I just got home last night from a 2 week fossil hunting trip. We loaded up the trailer and made our way up north to the Hell Creek formation in South Dakota. This was the 11th year since we started digging with Walter Stein of PaleoAdventures. We spent 4 days in the field at his Tooth Draw quarry. This started out pretty slow for us, with an Edmontosaurus neural arch with processes but was missing the centrum. My son found an unknown plate. Highly fractured but it looks to have 3 original sides. The underside is still encased in matrix so we wont know more until its prepped out while might take a while. The finds got better in last 2 days. We found a few big BOBs, lots of Trike spitter teeth, and then a nice limb bone, possibly from a crocodile. The last day gave up a wonderful complete Thescelosaurus vert with all processes. It may not be clear in the pic, but its all there in the matrix. Then came a Nanotyrannus tooth, a partial mammal jaw, a possible piece of turtle plastrom and a final tooth with could be nano or could be raptor. It will have to be cleaned to examine it better for a good ID. Sorry, I dont have a field pic of that one. The weather didnt get better though. Our last day it in the mid 90s, zero clouds and 40mph winds funneling down the draw and sandblasting us all day long. But with great finds, you couldnt pry us out of there.

Out collecting the other day at an Eocene site on the Potomac, one of my kids came up with THREE cool verts! We think they may all be snake verts, but we wanted to get a second opinion. Any thoughts?

Hi everyone, I've been hesitant to post this fossil on here for a while as I didn't know if I wanted to hear a response which would contradict what I had hoped this would be. However, I recognize that to maintain a reliable and accurate collection I would have to properly identify what I found. The fossil in question is a possible partial egg that I found last year in the White River formation of Wyoming (Late Eocene/Early Oligocene) w/PaleoProspectors. This formation is known to produce fossil bird and reptile eggs (in fact, someone found a large, complete egg on this ranch the week before I was out there) so I knew that there was a possibility. When I found it most of the inside still contained sediment, which I have since gently scraped away to the best of my abilities. It has an odd dent in the top and no obvious pores, but the overall shape and the apparent shell make me think this is an egg. It is 8 mm tall and about 10 mm in diameter. I want to know what you all think. I would especially like to hear the opinions of @CBchiefski @jpc @MarcoSr @Auspex@Troodon Interior of the egg before I cleaned out the matrix. After I scraped away the matrix. Here's two views of the top.

Hi guys recently recieved these nice sharks teeth, the info on them was just zhotymyr quarry, Ukraine, I assume it’s Eocene from the species ( if I got those right) but any extra info would be greatly appreciated 1.carcharias hopei 2.odontaspis spp.

I purchased this fishy piece a while back, as it was dirt cheap. It’s not much, more of a “fish finger” or “fish stick” than an actual recognizable fish, but once I got it in hand, I realized there was more buried in the matrix. Since I paid so little for it, I figured that when I had time, I would try my hand at prepping this little guy out to see what more I could reveal. I found some time today while outside watching the kiddos play, so I gave it a shot. It’s a fish fragment from Kemmerer, Wyoming. Eocene in age. What was initially revealed is only about 2cm long. This is what the piece look liked when I purchased it. Closer inspection showed more peaking out from the edge. I used my engraver on the lowest setting to slowly and carefully chip away the matrix. What fishy secrets will be revealed? This matrix is super soft compared to the local limestone that I’ve gotten used to digging around in. I have a new respect for the fish preppers out there! ( @Ptychodus04 and @RJB ) The tiniest slip would send a chunk of delicate bone flying, and with the soft, thin, almost chalk like matrix, a tiny slip was very easily done. The matrix was only a millimeter or two thick above the fossil so slow, careful, and deliberate movements were a must. A few more minutes revealed what seems to be the makings of a tail. This is as far as I was able to get until the kids wanted lunch. They think they need to eat a few times a day or something. Geez! The whole revealed piece is around 4.5cm long. It looks to be a tail, but that is as about as far as my knowledge goes regarding fish fossils... It still needs some cleanup with the pin vise and a consolidant added, but I think most of it is uncovered. Sorry for the slight red tint on this pic. I opened the umbrella for shade and didn’t realize it cast a red light on everything until after getting back inside and looking at the pictures. It was a fun little prep and I enjoyed trying my hand on a different type of fossil in a different matrix than what I am used to. A nice change of pace. Now where did I put the tarter sauce?! No wait... I need custard! Fish fingers and custard!

Went up to Douglas Pass, Colorado today for a hike with my wife. I have always hunted for fossils at the Radar Dome location. Today we decided to scout around for another location to collect. Hiked up a very steep hill to a shale exposure and found this larvae after only 1 minute of looking. We had not come prepared today to collect anything. Will probably head back up next weekend. The larvae is approx 2.25 cm across. There are also some parts of other larvae on the piece.

From the album: Misc. Cenozoic Specimens
This specimen is on the boundary between auriculatus-sokolovi in my opinion. -
I have found several of these fossils over the last few months and would love some help identifying them. Most are small, less than 1 inch long and difficult for me to photograph with any real detail. But the last one I found is much larger by comparison. It's just a fragment but it's about an inch and a half long and 1/2 inch wide. They all taper from one end to the other and they all have raised bumps down one edge and a deep groove along the other edge. The flat sides are textured. They were all found in a creek in Southwest Alabama, US alongside Eocene shark, ray and sawfish teeth. Suggestions so far include silurid spine, stingray barb, fish jawbone, and a piece of Noah's Ark. I have not been able to find matching examples of any of them. Any other ideas, or pictures to confirm one of the previous suggestions? I posted some videos I shot if that helps. Not sure if it's permissible to link to them here so apologies if not... Thanks!

Ammonites, Trilobites, Fossil Fish: Another Western Adventure
Jeffrey P posted a topic in Fossil Hunting Trips
Barely a month had gone by since my last trip to New Mexico and Colorado, but I already had plans for this trip in the works. Primary focus this time, which was a solo trip, was fossil collecting, visiting well known sites that have been on my radar for quite some time. I flew out to Salt Lake City and drove directly to Kemmerer, WY. My first stop there was Fossil Butte National Monument: Here is a view of the visitors center (free admission) and the surrounding barren, but awesome landscape that surrounds it:

I've been going through my collection lately and fixing labels, etc. Just wondering if these are correct. I'm not sharp on my Green River fauna, or fish in general. These are the extent of my Green River collection, aside from a larger Knightia. Sorry, these indoor pics aren't great, I'm hoping someone with experience here will be able to tell what they're looking at, otherwise I could try for better pics outdoors next time we have sunlight. If there is any more info you can give me as well, such as which specific layer these probably came out of, I'd appreciate it. This label initially had 'Knightia' but that was crossed out and replaced by 'Fontenelle':

I collected these beautiful ball-style fossils a few years ago from around the Hajar mountain area in Oman. I still don’t know what exactly they are. They were just lying in amongst the desert sand within the mountain (known for marine fossils from the Eocene to Miocene age) I’m guessing maybe they’re a type of solitary sponge or coral? I would be so grateful if someone could please help with the identification. I’ve taken as many photographs as possible, including some cross sections from broken fossils. The last 2 photographs show an additional species of fossil ball which I cannot identify either. The 2 new mystery ball fossils appear to have trapped other small marine fossils (nummulites) inside their fossilised bodies. Thank you so much for any information you can offer.

Hey All, I found this tooth in some micro material from a creek in Castle Hayne NC. Was wondering if it was fossilized or not. Other material found were really worn small sharks teeth from the Eocene Castle Hayne Formation. Thanks.

I hunt Eocene era Marine fossils in South Alabama. I have found a ton of thins but this one has me stumped. It's roughly 1½ inches long, ⅜ of an inch thick, and ⅜ of an inch tall (Sorry no metric ruler). On one edge, it appears to have small pointy teeth while the other side has some what of a channel. I've been able to identify most of what I have but I need some help on this one...

I took a trip yesterday (Easter Sunday) morning to a few river sites in a neighboring county. The first spot I went to is a Pliocene exposure of zone 2 Yorktown Formation. While I found the normal culprits of teeth, mako's, hemi's and a small meg; it was the unexpected find that made this trip. While I have found fragments, I have not found anywhere near a complete echinoid there. Well Easter changed that, the Echinoid Bunny left me a good egg. I found a gorgeous complete Arbacia improcera. A rare Pliocene echinoid, my first. As found: after the first cleaning: second cleaning: third and final cleaning:
