I do not always attend my fossil club meeting, but made an exception last night. @minnbuckeye had generously donated some fossils for the upcoming club Auction (Thanks Mike) at the March Meeting and I was delivering said donations to the Auctioneer. Also we had a cold front coming in today , so I was out hunting yesterday. Found a couple of 100s small shark teeth, 4-5 turtle spurs a couple of mammoth fragments and some random bones, not much else. After hunting , grabbed burgers & fries at McDs , arrived to the club meeting an hour early. I also had a ziplok of fossils from my previous time out, which had some excellent fossils in it... like a mostly complete whale cookie..* (see below) I went back to my tailgate and was sorting fossils between a few I wanted and the rest to the prize table for tonight's raffle. A car pulled up next to me , lo and behold, it was Richard Hulbert, tonight's speaker on the Florida Fossil Permit and maybe an update on the Montbrook dig (https://www.floridamuseum.ufl.edu/montbrook/) which he leads.... I could not have been more pleased... Richard started to identify those random bones left and right... This one was heading for the donation pile until Richard said, "Artiodactyl, ankle bone, maybe bison, complete...." That is more that enough to track down one of @Harry Pristis outstanding identification photos (THANKS Harry ) and that definitely reduced the possibly IDs for this fossil to.... wither Bison or modern cow. If Harry has a right side ectocuneiform, this one is also... My "feeling" is that this one is hard fossilized, but as I have seen previously , size may be a differentiator. So Harry, if you see this thread, let me know if you agree with "right" and have any reason to believe more likely Bos than Bison.. Whale Cookie !!! (I actually think of them as Oreos, but they do not have that chocolate taste...

Hey all, I found this little vertebrae at my usual location, sticking out of the mud that comprises the Rio Dell Formation, Pleistocene in age. The best I can identify it as is a Filefish Vertebrae. Doing a quick Wikipedia search, I learned that some species have been known to enter lagoons and estuaries, which is good news for me since the Rio Dell represents an ancient bay environment. Ive attaches a reference image of some file fish verts from North Carolina. (Source Here: https://www.fossilguy.com/sites/l_creek/lcrk_col_fish.htm) Id love to hear all your opinions. And thank you for all the help that you guys have given me thus far, this is one of the best communities on the internet.

Fun North Sulphur River Texas hunt today. The Plesisoar podial is huge. The mosasuar jaw section has teeth hidden under the red matrix. The big mosasaur cervical vert is in great shape.

Good evening everyone, long time I don't show up here (my bad, my thesis is ...well...a thesis). Almost 2 weeks ago I had the pleasure to visit with a friend the "Museo Civico di Scienze Naturali Malmerendi" located in Faenza. Even if it's not the biggest nor the most famous natural history museum of Emilia Romagna I consider it one of the best I've seen so far in Italy. Most of the speciments (Pliocene / Pleistocene) were collected in the area near the city. Mammals are well represented, maybe the most peculiar is what I think is the holotype of the only aardvark specie from our country (if I'm wrong please tell me). Several fishes (in particular a large grouper in matrix) and mollusks are also displayed.

Hi Everyone! I should preface that this collection of photos were taken on multiple occasions to this location. I just wanted to share with you all typically, what my experience fossil hunting is like. This is not the only location or formation that I personally collect from, but it is the most frequent location I visit and is relatively accessible at all times of year. Anyway, essentially what we’ll be seeing here is the deposits of a 2ma old bay, represented by the Rio Dell Formation, then the Carlotta Formation, orange conglomeritic sandstones representing a delta that flowed into said bay, all uplifted by a faults driven by subduction. ON TO THE PICTURES!

I was browsing through some past finds and came across these 2 teeth that I had placed with deer material. Just wondering if there’s any chance that these are actually llama teeth?

I posted a short trip report, and included this vertebra which i can't id. It is almost perfect. I put it to a flame test because I thought perhaps it was recent, but no smell whatsoever. It is about 1"wide from wing to wing, and also about the same from the bottom to the tip of the top flange. I fell in love with it as I pulled it out of the chalky white clay from the bottom of the stream where I was screening for shark's teeth. Thanks for the help.

I bought this bit of Madagascar copal a year ago, then finally got a decent microscope to see the bugs this week. They are less than a mm each. Now I'm stumped. I am a certified *modern* naturalist. I know something about insects. This one fits all the defining characteristics of an adult insect - probably Coleoptera - except that I only see four legs and may or may not have had antennae at some point. The heads are not very clear at any angle. On the bottom view, there are nubs at the end of the abdomen that *could* be legs, but that is the wrong place for insect legs. On the side views, it looks like there might be legs folded backward, as is common with some beetles, but the underside view also does not show any attachment points where there might have been legs that broke off. Any paleo-entomologists out there to point out what I am clearly missing in these pictures?

I found this skull sticking out of the bank along the Tongue river in Ashland, Montana on the Cheyenne Indian Reservation. If anyone has any information I would love to find out more! Thanks.

Hi guys, I'm new here! I just wanted to ask if the burn test is always reliable. A year ago I found a tooth near a creek, it's certainly bovid but I still can't understand if it's a modern one or prehistoric/Pleistocene. I've burnt it and it doesn't smell like burnt hair, but at the same time it kinda smells weird. So does the burn test always says the truth?

Pulled this 6 inch square bone out of clay, shell, mud, sand, and a little gravel. It has retained many of the fine details and blood vessels. Initially I saw the horizontal bands and thought mammoth teeth plates, but not to be. So, large , broken bone I am pretty positive is lower jaw. I the 1st photo, I seem to see a Mandibular Symphysis groove moving directly left from the tip of my thumb. I am thinking Mastodon, but also wonder if Bison or Giant Sloth is a possibility. I hope that some other hunters have seen the kinds of parallel grooves present in the 2nd photo. Could these be huge blood vessels?? All comments and suggestions appreciated. Jack

Hi everyone I've been looking for a Megalania tooth for a while and I saw this and a few similar looking ones for sale, does it look like megalania to you, measures 2.1 cm long?

When I get home after a hunt, I sort and spread out my good finds, to take photos and then have another pile of fragments and broken bones. I have gone back to that 2nd group to highlight some I am unsure of the ID. The location I was hunting produces mostly late Miocene fossils. Here are a couple .. 1st a broken bone. A friend hunting with me said Deer metatarsal. I am not sure after finding this deer metatarsal from North Florida on the internet, which has a clear groove down the center: and the bone I found which is flat in that section. Could be wear or different type of deer or different mammal. 2nd, a strange tooth fragment ??? While I would love to have an ID, that might be a bridge too far. I settle for anyone who has insight on the nature of the material on the left of this last photo. Is that enamel, tusk ? For example this is very different from fragmented teeth from horse or alligator, or whale... Thanks for all comments & suggestions. Jack

I hope there’s enough of this piece to correctly identify. It looks like a proximal tibia of something large like bison, horse, camel or maybe tapir? @Harry Pristis,

I have found numerous pleistocene period bones on river sand bars in central Iowa. Here are a few unidentified bones I am asking for help identifying. #1 sure looks like bone but I have no idea what it is. I would say fish except for the bone characteristics. #2 is a small digit bone and has some age. I have not found anything like it at that size in my google searching. #3 is also bone and does not have the look or texture of an exposed claw. You can see where another bone connects. #4 I do not know what animal this is but it appears to be an old bone that my wife unearthed along the river. Thank you so much!

Hello, fellow Fossil Forum members. Last summer I found this bone fragment in Crystal Beach, Bolivar Peninsula, Texas. The fossils from the upper Texas coast are from the very late Pleistocene Beaumont formation. At first, I didn’t think anything of it, other than it just being a bone fragment. But now I’m thinking it might be a very worn down claw core from some animal. But I’m not sure, it could just be a plain old bone fragment. So let me know your thoughts on this specimen. Front view- Specimen measures 30 mm (1.2 inches) long side view back view- showing different coloration on the interior another side view The bottom view- it has a black coloration. The bone fragments from this formation are often multicolored.

I found this vertebra in Bartow county Florida along with some other mammal Pleistocene fossils. It was found in close proximity to some deer antler pieces and Mastodon incisor pieces. I found an almost identical vertebra online that said that it was a giant ground sloth vertebrae. The piece is heavily mineralized. Any opinions on this vertebra would be greatly appreciated. It has a diameter of 2 1/2 inches and a width of 1 1/2 inches.

I have been hunting in the Peace River so long that anything I can not identify must be unusual. Small molars are difficult. Maybe @Harry Pristis has seen this before. It is 7 mm long and 5 mm wide. I also said Canine.... a little broken but it has character !!! 2 inches in length All comments, guesses, and identifications appreciated.. Jack

Hello fossil folks! I am going through my bone collection from last season and would like to identify the five bones pictured. The most interesting one to me is #5 as I believe it is too long to be a horse. Perhaps camel? All of these bones were collected from a river in central Iowa. So far, my wife and I have found prehistoric bison, horse, sloth, mastodon and mammoth bones from the pleistocene period. I am pretty sure these are either Metacarpal or Metatarsal bones. Sorry but I do not have a metric scale for the pictures. I have labeled the bones 1 thru 5 and noted each bone length. Thank you!

Here are three more Riker mount displays (8”X12”) that I just put together with my macro specimens from the Miocene and Pleistocene of Virginia. The first two displays contain Miocene crab specimens in concretions. My sons and I have probably several hundred of these crab concretions. Unfortunately the quality of these specimens isn’t like the great crab specimens that come out of the state of Washington but they are still interesting to find. The second display also has a few borrows. The third display contains some miscellaneous specimens like petrified wood from Pleistocene bog iron of Virginia, Miocene terrestrial mammal teeth including a piece of a Gomphothere tooth, bony fish specimens like opercular series bones, tilly bones and sturgeon scutes, and some bivalve shell internal casts. Also in the display, bottom far right, is the only piece of a burrfish mouthplate that I’ve found in the Maryland/Virginia Miocene. Here is another 8”X12” Riker mount display that I just put together with macro specimens from the Miocene of Maryland and Virginia. This display contains some of the very first fossils that I ever collected dating back to the 1970s. In the early days of my collecting I only separated my macro fossils by age/time period and not by formation or location also. So I’m not sure of the location that a lot of these specimens were found at. Most are from the Miocene of Maryland. However I do remember that the two dark gray Otodus megalodons were found by me on the same day diving at Governor’s Run Maryland and that they were my first megalodons ever collected. I also remember collecting the ocean going sunfish jaw at Plum Point Maryland and the thickest sperm whale tooth at Stratford Hall Virginia. Marco Sr.

Kyiv at the Academy of Sciences of Ukraine Archeological Museum. Mammoth shoulder.
Andriy posted a topic in A Trip to the Museum
Hi! I visited the museum today (Kyiv Archeological Museum). And noticed the thing I had seen before (in 2017, in Vienna Natural History Museum). It's the mammoth shoulder in which zigzag ornament inflicted red ochre. This thing occurs in Mezin. The site is one of the better-known examples of Magdalenian culture in Ukraine. (sorry for the low-quality photos)

I found this hollow bone in an area on Northeast Texas that has a mix of Pleistocene and Cretaceous fossils. I sent the pics to two paleontologist and one thought cretaceous bird and one thought it was a raccoon distal left radius. I wanted to see what everyone thought. It's definitely a hollow fossil bone.

Hello folks. I'm back after an extended break. I've found some really cool fossils on my land in southern Missouri, Texas county, USA. Just a few miles south of cabool. A seasonal stream flows through my land exposing some cool finds, not to mention- the heavy rains are washing the topsoil away. From the hundreds of artifacts I've collected, this spot must have been an indigenous settlement. My best guess is that this item was in the hands of those early Americans. I can see why, this is my 2nd most favorite of the collection. Please help me identify what this is. Any help would be greatly appreciated. FYI, I have overcast skies at the moment and very limited internet access. These pics are the best I can do. Mm measurements are roughly 66mm x 38mm x 25mm
