Hi all! I’m hoping to solve a mystery. I find these objects pretty regularly along the San Mateo coast of Northern California. I’m not even sure they’re fossils, but the bluffs above the beach are part of the Purisima Formation with plenty of fossils from the late Miocene to early Pleistocene so I thought it would be worth a try. They look to be made of compacted sand, like a concrete, but laid down in layers, with a more robust top with lines that have some shell-like material. Most pieces I found have this triangular shape that look like they might have formed tubes. All the pieces I’ve found look like they would have a similar diameter. I’ve never found any smaller. They’re pretty uniform. And common. Since I first noticed them a couple of months ago I find them every time I’m on the beach. They could be the result of a geologic process, but I’ve asked every beachcomber, zoologist, and marine biologist I can can find and no one can tell me what they are.

The stars have finally lined up : schedule, health, weather, funds, and river gauge. That means it's time to hit the river again! Tomorrow I am going to a location that is one of my secret honey-holes. Let's call it "Alpha". It's on the Peace River and has produced plentiful Pleistocene and Holocene specimens. Want a fuzzy clue about it's location? Ok, here goes : it is in a counter-intuitive spot that is easily overlooked. That's it. I have not laid eyes on Alpha for months, so I am unsure what to expect. Hopefully it is fruitful (it usually is). Only three other people on the planet know where this spot is - my wife, my stepson Josh, and my daughter-in-law Alaina. Tomorrow my wife and I are going - so wish us luck! The truck is already loaded up and we will be on the road when the roosters are crowing. I typically post a report after the trip, so that report (and photos) will go here via replies. Stay tuned...

This was a beach find from Ponte Vedra FL, near Jacksonville. I have found a variety of fossils there from a Pleistocene bone bed offshore – mammal, reptile, fish, etc. The shape reminds me of a claw and the texture seems layered like a hoof, but maybe I’m projecting. Can anyone identify it?

On Saturday, I met up with two TFF members for a hunt on the Peace River. It was cool (cold) at 8 am, especially in the shade, but the best fossil location was in the shade. While many fossil hunters have certain qualifications for "keepers", I keep almost everything, especially a fragment that I can not ID. I also keep a lot of fossils (like turtle) that many hunters toss. Weather wise, we had a fantastic day. Especially when the sun warmed up and covered out hunting location... the wet suits came off. Here is a photo of some of my finds: At first, I thought upper_right would be my Find of the day...but there is something else, very interesting in this photo.... The above photo is a Glyptodon scute, that Strongly resembles a strawberry. It only has TWO !!!! connection points to other scutes. I have never seen another like it , and I have seen plenty of Glyptodon tail scutes. So I will be searching Glyptodon for this scute --- Help me find it.!!!! And this is an earbone... I think I know, but whose ?? There are many "common" fossils in the 1st photo. Can anyone Identify all the fossils in the photo? Saturday was a great day. Great variation in finds. I went again today, In addition to back pain, I only found ray, barracuda, and shark teeth.. Best find was a 1.4 inch hemipristis.. Today was overcast ,and chilly. It was also a great day. I was on the Peace River.

My better half has been away for the better part of two week, severely limiting my hunting trips. Today I managed to get away to a location on the Peace River where I have taken some TFF friends previously. It was cool 53 degrees driving there , but once the sun came out , it was OK -- as long as I had my 5 mm wetsuit. I was by myself because getting a dog_walker was a last minute offer. This location has a line -- clearly Miocene marine on one side and Pleistocene mammal on the other. I had found some medium sized Hemis, 5-6 Armadillo osteoderms, about half of a good sized dolphin tooth, some gator teeth, a couple of verts... no fantastic finds but a very soothing experience on a bright sunny , cool day. So, I am thinking last sieve, and this comes up.. for a second laying in the sieve , I thought it was whole.... but no. I did go back for a couple more sieves to try and find the rest of it, but no such luck. Carnassials are very distinctive. I think this is enough to not only identify the mammal, but also the exact tooth position. The length of the broken enamel is approx 13 mm. Enjoy !!! Jack

Hunting for Miocene shark teeth in the Wienerberger quarry in Rumst (Belgium)
ziggycardon posted a topic in Fossil Hunting Trips
Last saturday I went on my 2nd fossilhunt to the "Wienerberger quarry" in Rumst (Belgium) with my girlfriend and the BVP, my fossil club. This quarry is only accessible for fossil collections during official excursions organised by fossils clubs. The quarry existed out of multiple layers, the oldest was a oligocene clay layer dating back to the Rupelian (named for the region) around 33.90 - 20.10 mya, although I didn't hunt in that layer, some of the finds that could be done there were bivalves, gastropods and brachiopods. The layer where most people hunted was a very thin miocene layer dating back probably to the Burdigalian around 20.43 - 15.97 mya. The most common finds here were multiple species of shark teeth and some marine mammal fossils. And then there was another layer were it was possible to find Pleistocene fossils dating back to the last ice age, but the chances of finding anything there was quite slim. So me & my girlfriend and most of the other fellow fossil hunters mostly hunted in the miocene layer in search for fossil shark teeth. The overlook to the entrance of the quarry, looking at the oligocene clay layers. Everyone digging for and sieving through that thin layer full of miocene shark teeth Me looking for some teeth My girlfriend looking for some teeth And while we were digging for the layer like everyone else, the finds were a bit meager at first, not just for us but for everyone. But then my girlfriend found a tooth a bit lower on the hill and we started scraping away the top layer of sand. Turns out that some previous land slides washed the best material down hill, lower than were the rest was hunting and so the spoils started coming. We found most material there including our best find, a 6,5 cm long C. hastalis tooth found by my girlfriend and a partial marine mammal vert found by me! I believe our hastalis tooth was the 2nd largest tooth found that day, only a megalodon found during the trip was bigger. As the day was drawing to an end and our spot was becoming depleted of fossils we took a walk around the quarry to look for a new spot only to return to our old spot to start digging towards the miocene layer again. But this time a little bit more to the right. We found a few nice shark teeth while doing this and a lot of iron concretions but but much else. Only during the last few minutes of the trip I did hit something that wasn't a concretion. After some digging it turned out to be a piece of wooly mammoth (Mammuthus primigenius) which ended up a little bit above the miocene layers during a previous land slide..jpg.fe297732c7acc48a6d01d064479ed620.jpg)

I, my son and grandson went canoeing yesterday on a river in SE Texas. My son spotted this from about 50 yards away on a gravel bar. I'm pretty sure it is Eremotherium but wanted confirmation as it would be a scarce find here. It weighs about 11 lbs and is about 8 1/2 inches wide maybe 9 inches tall. Any input? @garyc @ harry_pristis @ shellseeker @uncle siphuncle @PrehistoricFlorida

I get out hunting as often as I am able. In addition to the fossil finds, I am at a point in life where exercise has great value and fossil hunting the Peace River watershed 3 times a week does get the muscles moving and the blood flowing. Add the great feeling with getting out into nature which I share with numerous animals of all types and this is just about a perfect hobby, BUT, not always a successful one. I think that I, over the long run, find one impressive fossil a week... What about this week? A lot of folks are saying that the Peace River water depth is dropping and this is open for success in fossil hunting. Last Sunday, I went to one of my favorite locations that have been very successful for me in the past, as recently as last spring. I usually kayak to to/from this location for an hour each way and hunt shovel and sieve for 5-6 hours --- good exercise. The Peace River is still high. Right this minute , the USGS gauge at Zolfo Springs is over 7 feet. That is un_diggable, except in isolated spots. You need to cling close to the banks and the currents are fast. !!!! I found a couple of chipped Equus teeth, turtle shell and spurs, 120 small teeth 70 % broken. Largest of the small shark teeth were 3 30-40 mm hemipristis (2 lowers and an upper). I did enjoy the day, sunny, cold out in nature. So , Monday was my 2nd day out to the Peace River this week.. Somewhat better, with 2 frequent fossils hunting friends, staying close digging in a 2 foot layer that had been uncovered by the heavy summer currents. They found it and invited me to partake. Not a show stopper , but some good fossils. I tend to remove (and donate) broken and small shark teeth from my "finds" photo. So the finds from a home to home 12 hour hunt. Some osteoderms, barracuda teeth, a few larger Lemon and Hemipristis teeth, a broken tapir, broken llama incisor, Thresher tooth (relatively rare). and then some closeup photos below. I liked this last hemi best and another sun_shiny day in paradise

I found this bone years ago on the Brazos River and never got around to asking for help with an I’d. Could this be from a bird? It seems hollow, but well mineralized.

Pleistocene mammoth fossils of Tomales Bay, Marin County, California

One of the guys hunting with me today found this canine and asked me to identify. I was surprised how laterally thin the tooth is. I am pretty sure we will identify. Please state the characteristic that makes your ID correct. i.e what differentiates from similar sized mammal canines? The standard experts: @Harry Pristis @PrehistoricFlorida. EDITED, sorry. The top edge close to the tip (Photo #3) is worn presumably by grinding against the opposing canine. All comments & suggestions appreciated. Jack

A collector/dealer recently donated to our museum a small collection of Pleistocene vertebrate fossils (mostly mammalian) from Florida. Only a few items were labelled, and he could not recall any provenance for some of the material. Even though the material was poorly provenanced, it will make a welcome addition to our comparative collection of Pleistocene vertebrates. Can anyone help me with the provenance for the llama/camel (cf. Hemiauchenia) calcaneum in this phone-camera snapshot? I thought the attached oyster shells might help in narrowing down the possibilities. I was given a verbal location for this specimen (there was no label), but I am skeptical. Thank you!

Hi. Found these bones yesterday at gravel pits facility where workers separate big rocks from the fine sand from Great Morava river. They don't burn at all or smell like a burnt bone. Here are some photos if someone can help me identify them : I know for one that is radius bone from Bison/Bos, but don't know about the others. P.s. Also u can see that one bone has something similar like "scars" from a possible flint? Please help! Darko

Hey everyone! On Wednesday, as I finally had some time, I decided to take Sara out to my favorite hunting spot: the Zandmotor (Netherlands). I definitely did not regret that decision! If you've never heard of the Zandmotor before, it's an artificial beach extension just south of The Hague, and the sand that was used was dredged from the North Sea and is full of Ice Age megafaunal mammal bones and tons of Eemian shells. If you want to see some more of my finds and hunts there, just look up "Zandmotor" in the TFF search bar and you should find a bunch of stuff When we got there it was raining, which annoyed me a little bit because the forecast said it wouldn't... The rain also makes the sand stick to the fossils which can become annoying when looking for small fossils or trying to recognize the thing you just picked up. But, having just spent an hour in the bus to get here, I didn't want to turn back immediately. Luckily the rain stopped within half an hour, and I wasn't even on the Zandmotor yet (I have to walk about an hour from the bus stop to the Zandmotor itself) and after that the weather alternated between cloudy and sunny which was nice. While I usually always take a pass by the shell banks, today I decided to only walk along the shoreline to increase the chances of finding good mammal stuff. In fact, there had been a strong eastern wind on Tuesday which helped uncover a lot of the bones and make them wash ashore. This did not go unnoticed, there were a lot indeed! Here is my first big find of the day, a great complete horse astralagus!

I found this bone in Florida's Peace River in a gravel bed that contained Pleistocene and Holocene land vertebrates. I am unsure about this bone. Is it a small deer, or is it a turkey bone? Or, am I entirely wrong and it's an alligator? Thanks in advance! MikeG

Hi gang, been awhile...I was puzzling over these two items below again. Found several years ago here in Florida. One a possible osteoderm? and the other an ungual? Mio/Pliocene? or Pleistocene? in age. First specimen I thought was some type of tortoise armor, has a concentric wafer shape and is about 3 cm across and about 1cm thick. Under closer inspection there appears to be an odd fracturing going along the outside and also some minor cracking which appears to be forming a hexagonal outline/pattern....Just a coincidence? Do any glyptothere osteoderms show an internal hexagonal pattern? Left photo is ventral? and the far right photo is the opposite side--dorsal view? Middle photo highlites the fracturing/cracking patterns.... 2nd specimen I thought was a tortoise ungual but in looking at several older threads I'm now wondering if it looks more like it might belong to a glyptothere? Its only about 2cm long. Thanks for any/all help. Regards, Chris

I found this today on the Brazos River in SE Texas. At first I thought it was a chunk of a vertebra. After washing some mud off I was surprised to see teeth with roots extending to the broken ends of a mandible. Based on the shape of the teeth I think it is a xenarthran, but which one???

Hi people! I have something to show you, it's from last years fossil hunt. I went last year to a beautiful Cave in Zabrega, (Paraćin) to try to find some pleistocene fossils. The Cave itself is not so deep but it's very wide and very big. I did found some bones and teeth which are half recent and half fossilized i guess? I found also pottery so it could be archeological but idk honestly. I'm here to show you my "biggest" find - it's a vert. not sure if that belongs to a deer or something else. You decide Thanks for help. Darko
