Hello everyone, Been a while since I made a post. Back in December I found a nice shell: Looting Lincoln Creek - Fossil Hunting Trips - The Fossil Forum. I'm not good with shells, I assume it's a conch of some kind. Anyways, having it out of the matrix has renewed my interest in it, and I was hoping someone might be able to tell me what kind of shell it is. Was also wondering if anyone knows a way I could keep it from falling apart, maybe with something I can coat it in. Just holding it for the picture, it felt like it was about to crumble to pieces. It is

My younger son Mel just led his first fossil trip of the year on our Oligocene M&M Ranch in Nebraska last week. My sons, Mel and Marco Jr., are starting to get back from their prepper some of the fossils that they found on our ranch in 2018. Not all fossils go to the prepper. Mel preps some of the specimens himself. Below is a picture of the specimens Mel found in 2018 that he will prep. Here are a few pictures of 2018 specimens just back from the prepper.

A few weeks ago I completed a road trip from New Jersey to Texas for work and although Hurricane Ida sadly canceled nearly all of my plans, I was able to sneak in a couple quick fossil collecting stops. One such stop was at an outcrop of the Oligocene Vicksburg Group in Mississippi. I was primarily looking for echinoids- I sadly did not find any- but ended up finding this small shark tooth. I am by no means an expert on shark teeth and have tried in vain to research Oligocene sharks of Mississippi. Does anyone know what shark this tooth is from or of a good resource where I might be able to fi

I've noticed that despite finding loads of petrified wood deep in East Texas (around Jasper, just east of Lake Sam Rayburn), I've never heard of any vertebrate material being uncovered in the area. I specifically spend a lot of time hunting petrified wood on the catahoula formation ( which is Oligocene) when I'm there, and there's definitely no shortage of said petrified wood. If so many trees are fossilized, shouldn't there be fossils of the animals that lived along side them too?

Since the spring my wife and I have been very busy with the garden and the orchard to maintain, the canned vegetables from our production, and we decided last Thursday to take a break for a geological excursion south of Clermont-Ferrand. The goal was twofold, to search for stromatolites and to take advantage of the volcanic context of the region. The detailed geological map of this area is unavailable but we had serious research ideas for our prospecting. The day began with a visit to a magnificent village that immediately immersed us in the context: Saint Saturnin. The walls

Looking to trade for Mammal Fossils
MeisTravis posted a topic in Member Fossil Trades Bulletin Board
I’m looking to trade some of my fossils for some new mammal material. Interested in carnivores, megafauna (focus on sloths but everything is of interest), titanothere fossils, but I’m willing to hear any mammal offer. Primarily interested in trading for teeth but always interested in hearing others too! Will provide any further pictures requested for interested people! Pretty little Chub, I don’t have any locality info on it but it is a nice little guy. 1.72” Attractive little Low Country Meg. 2.13”. Some Pleistocene armadillo scutes and turtle spurs. T -
It has been forever since I have posted on here, but I need help Identifying an unknown fossil. This fossil was found around Charleston, South Carolina along with many Angustidens and other shark teeth. This fossil appears to be approximately 4.5 inches from tip to base. I believe this fossil comes from the Oligocene epoch. Please check out the very center and the growth rings. Thank you very much for the help! I am identifying this fossil for a friend and the fossil is currently located in Charleston, SC, so I am not able to take more pictures of it.

First South Carolina Fossil hunting trip
Lando_Calrissian_4tw posted a topic in Fossil Hunting Trips
Made my first fossil hunting trip to South Carolina, went to some areas around Summerville, thought I’d share pics of some of the fossils I collected! The best finds were some echovenator-like teeth, Angies, great whites, some intact sections of dugong ribs, and several associated pieces of a sea turtle shell. Felt like Indiana Jones exploring all the creeks trying to find productive spots haha. Fun trip, hope to return in the future!- 7 replies

I was recently out vacationing in Wyoming and spent Saturday morning (7/24/21) hunting in the badlands. As I sat down to rest for a moment, I looked down and saw what I thought were a radius/ulna pair from a small mammal. Upon closer inspection, it was a pair of lower jaws freshly exposed on the edge of a nodule and on the backside, a small skull. Needless to say, I was ecstatic. I spent a bit of time making sure the specimen was consolidated (Paleobond Penetrant, wish I had brought some 4417) and packed it up for the trip home. I was thinking it woul

Hi guys, I have a few bits and bobs I would really appreciate help with identifying, let me know if you need better photos of anything thanks for your help lets start with some Oligocene stuff from Yarmouth, 1. Some kind of skull element, what from though? 2. This is very weird, it does remind me of a tiny croc scute though 3. Some kind of ankle bone? and some from the lower greensand of whale chine, Isle of Wight, it is a coral, but not the usual holycites elegans, a book I read mentions a very rare mushroom shaped coral, like this ma

Now that hockey season has ended and the lab is warm again, and perhaps due to my new found extra time in isolation, I am embarking on documenting my prep projects. I thought I would start the prep season off with something easy that should turn out fairly nice. Please welcome my new little friendly Oreodont, Miniochoerus gracilis. It came into my collection in the summer of 2013 and has sat jacketed in a box until today. This evening I concentrated primarily on consolidation and bulk matrix removal with an ARO, and still have a ways to go. The plan is to prepare the "down" side in the ho

With a week of collecting under my belt I felt ready and excited to take on the next, this time exclusively on the White River formation. All factors being considered, the White River is probably the most difficult formation to hunt among those I've been lucky enough to explore thus far. For one, the terrain is often very rough, with all sorts of ridges, rises, washes and gullies to hike through. Another issue to account for is the reflection of light off of the white sediments, meaning that ample sunscreen is a necessity if you don't want to burn to a crisp. That harsh sunlight can lead to te

Picked up a few more shells from the Lincoln Creek Formation while out on a walk, and thought it would be fun to make a composite piece with them. Was pretty easy, just used superglue to fix a couple of moon snails and a scaphopod to a tiny slab of shale from the formation. For my first composite piece I don't think it looks bad, but I was obviously a little too excessive with the glue.

I bought this large jaw section at MAPS a couple years ago. It was labeled fossil jaw Badlands and that's it. I've collected the Badlands of Nebraska, Wyoming, and South Dakota many times and built a large collection of fossils from these localities. However this jaw has stumped me. My thought was the large Miocene Oreodont Promerycochoerus. Any input will be appreciate. The size of the jaw is 153mm or a little over 6 inches long. The rear molar is 50 mm or 2 inches long. Thank You.

Adventures in the White River Badlands of Colorado
Opabinia Blues posted a topic in Fossil Hunting Trips
I just got back from an amazing and very fruitful week of fossil collecting on the White River Formation in northeastern Colorado. The White River Formation is a very easy and fun rock unit to collect vertebrate fossils on. The White River Formation was deposited during the very latest Eocene and the early Oligocene, though the faunal diversity in the areas I was collecting on suggest it was laid down during the Orellan North American Land Mammal Age, which centers on around 33 million years ago during the Rupelian age of the Oligocene Epoch. I am very lucky to have a grand uncle- 24 replies

This has bugged me for years. It's a small amphibian or reptile ( 8cm long) found at Fossil OR at the high school site. The strata is tuffaceous siltstone famous for leaf impressions. It's part of the John Day formation, oligocene in age. I have read that salamanders are occasionally found there but cannot find any more information as to species or anatomy. I was even wondering if it could be a snake with vestigial femurs. I'm hoping that someone can provide me some specifics so I can finally finish cataloging this specimen.

New fossils of giant rhinos — the largest land mammals ever — are found in China (nbcnews.com) Giant rhino unearthed in China was one of largest mammals ever to live | New Scientist New fossils reveal one of the largest land mammals ever found (yahoo.com) Since the late 2000s, scientists from China have treated Paraceratherium grangeri as a distinct species from Paraceratherium fossils found in Central Asia (named Indricotherium by Aleksei Alekseeivich Borissiak in 1916), and the taxon P. huangheense described in 2017 further indicates that not all fossils of Paracerather

I found this front bit of carnivore jaw while out on my latest fossil collecting trip in the White River Formation of Colorado. Only one tooth is complete, the canine tooth has broken off. It’s too large to be Hesperocyon and the cross section of the canine tooth does not match that of Daphoenus, which I have previously collected material, including a canine tooth, from. That leaves Hyaenodon and the Nimravids. After doing some comparative research with pictures of skulls, I am tentatively leaning towards this being from a Nimravid, as the contours of the jaw line near the socket

Prepping some White River Fossils - Guidance and advice needed!
Opabinia Blues posted a topic in Fossil Preparation
I have a few really nice fossils from the White River Formation of northeastern Colorado that I need to prep, and given I am a beginner at fossil prep I would really like to gain some advice and guidance from people with experience do I don’t accidentally damage the fossils. The first fossil is an Oreodont skull. The skull is mostly intact, and I was able to extract it from the field without using any glue or stabilizer or consolidant or anything like that, so this fossil is in its “natural state.” The zygomatic arch and upper tooth row are crumbling, but -
Carpathospinosus propheticus Tyler, Jerzmanska, Bannikov & Swidnicki, 1993

The spikefishes are related to the pufferfishes and triggerfishes. Taxonomy according to GBIF. Diagnosis after Tyler et al., 1993: "Carpathospinosus differs from all other Triacanthodidae by the first dorsal spine with a longer average relative length (37% SL versus 24%-34%) and the second dorsal spine considerably shorter, with an average relative length at the low end of the range of length in other triacanthodids (15% SL versus 13%—29% SL), its length contained an average of 2.4 times in the length of the first spine (versus length of second spine contained an average of 1.1-1.4 t- 3 comments
