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

I found this in the overburden at my work, which usuallly consists of the first 15 ft of dirt, clay, and sand, and below that is the Ocala formation in Alachua county Florida. the vast majority of the bones i find are deep in the redish-brown clay. ( The dark/wet spots are glue)

Hi all. I found this fragment in the surf at Westmoreland State Park, VA, which is part of the Horsehead Cliffs formation. I believe it's part of the miocene as the Calvert Cliffs are. I was just wondering if we think this might be a bone fragment? It looks like it has that spongy appearance of trabeculae. The fragment is just under 2 inches long (4.5 cm) and 3/8 inch wide (about 1cm). It's extremely flat on one side, very irregular and somewhat porous on the other. Vertebra, ribs, skull, perhaps from some marine mammal?

400 Million years in 4 hours The small-scale geology of Austria makes it possible to observe and collect invertebrate marine fossils from a time span of nearly 400 Million years (Ma) within a few hours and at a distance of only about 10 km: - 395 Ma old Devonian (Eifelian) corals - Ölberg - 80 Ma old Cretaceous (Campanian) rudists – St. Bartholomä - 12 Ma old Miocene (Serravallian/Sarmatian) gastropods - Waldhof I did this special hunting trip west of Graz at October 22, 2019 as a "feasibility study". The youngest and oldest fossils can simply be picked from the ground (or photographed); the “middle-agers” require some searching; I succeeded to find a few good specimens within one hour. Weather was perfect with nearly 25°C (!). Simplified geological map of Styria with the visited area west of Graz (red rectangle). Geological map of the visited area (1:50.000), composed of two adjoining map sheets. Red numbers denote visited fossil sites (and their age in Million years). Note the fossil sign in the blue formation in the upper middle of the map. This is the upper Devonian Steinberg-formation with goniatites. These fossils are not abundant, though, so I have never explored this hill… Topo map of the area. Red numbers denote fossil sites, A and B are sites of landscape pics. Just to show off some landscape: View from point “A” in Steinberg towards west. K = Kreuzegg mountain (570 m, Campanian St. Bartholomä-formation) at a distance of ca. 5 km. A = Plateau-like Amering mountain (2187 m, high-grade metamorphic rocks) at a distance of ca. 40 km. View from point “B” at Kreuzegg mountain towards north to southeast. Pano composed of 4 individual pics, spanning about 140°. Labeled mountains and hills in the background are: S = Schöckl (1445 m, Devonian epimetamorphic limestone) at a distance of ca. 20 km. P = Plabutsch mountain (754 m, namesake of the fossil-rich Eifelian Plabutsch-formation) and B = Buchkogel mountain (656 m), both at distance of ca. 10 km and located immediately to the west of Graz. Ölberg and Waldhof sites are between P and B, but not visible. Note the about 1000 m high, largely deforested mountains at the left side of the pano (Mühlberg, Pleschkogel etc., lower Devonian, dolomitic Flösserkogel-formation). The severe deforestation of these hills is due to a strong storm in 2008 (“Paula”). Continued...

I recently found a distressed canine in the Peace River. When possible I really want to identify all such fossil canines. The length is 1 and 1/8 inch. At the river I seemed to see (photo #1 & #2) "latitudinal banding" which means marine mammal. At home, I note that the root end turns to the side of the canine (photos #3 & #4), a characteristic that I mostly associate with porpoise. So , what is my question: Do all Dolphin/Porpoise teeth have such banding? The only reason I do not detect it on 95% of my Florida Dolphin/Porposie fossil teeth is that the banding is covered by cementum. I appreciate all responses, Jack Here is a picture of Whale tooth composition. These are Peace River or Bone Valley Whale Teeth:

Actually, it's not MY site. It's freely available for everyone and I do meet up with some enthusiasts there occasionally, but usually I just pedal out there on my bike and enjoy the peace and quiet. The most active creatures at this place are actually the wood ants in the summertime when they like to climb up inside my pants. I was there again today and this time I took along my camera for posterity's sake. Continued...

Hi everyone, saturday I went on my 2nd fossil hunting trip with my fossil club to the Wienerberger quarry in Rumst in the Rupel area near Antwerp (Belgium). We hunted mainly in a thin Miocene layer dating back to the Burdigalian around 20.43 - 15.97 million years ago. We found many shark teeth, most of which are C. hastalis, but there are a few I can't quite identify as shark teeth are not really my area of expertise and I was not acquainted with the location until my visit. So I was hoping some experts could me out or someone who is familiar with the species from the location. I did send an email to one of the excursion leaders from the trip, but he admitted not being a sharkteeth expert himself either and couldn't help me much further with ID's. So any help would be welcome. So the first batch of teeth are what I all believe to be C. hastalis. I am pretty confident with my ID on them but the other teeth are a mystery for me. These two teeth are pretty beaten up. The tooth on the right has no enamel layer anymore and I doubt an ID is impossible. But the tooth on the right could be beat-up C. hastalis but I am not sure, it also kinda looks like a pretty beat-up Carcharocles angustidens. The latter can be found at the location and are usually found in the bad condition due to the fact that they were present in a now lost layer a little bit older than the one were most shark teeth were. But as said before I am not an expert and I am just purely speculating with the little info on the location I have. I don't really know how to ID these teeth. Are they C. hastalis but located on different locations in the jaws than the previous C. hastalis teeth or do these belong to a different species? Then there are these 3 teeth that I don't know how to ID We also found a few small shark teeth of which I believe they might belong to a different species than C. hastalis And then the last tooth is this one, on first sight it kinda looks like a C. hastalis tooth but when you take a closer look you can see that the edges are serrated. So I wonder whether anyone know what species this could be? Well that were all, I would really appreciate some help for their ID's Thank you in advance!

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)

Hi Everyone, I was out at Glenafric in New Zealand with @Doctor Mud and found this concretion which might have a bone cluster in it. If anyone could ID it I would be really greatful!

Theese are from Evia island Greece an Upper Miocene site with fossils. Any idea what can be the oblong ones ? The cones are freshwater gastropods that can be seen. there is also round and some arced ones. Some have hole in the centre some not . The size also varies a lot from 1 cm to 10 cm

Hey. So today on a whim I decided to give fossil hunting a go. Took my family to the beach at Glenafrik farm, about an hour north of Christchurch, New Zealand. About 30 minutes in I stumbled across this beauty (beginners luck huh). Now I’m wondering, what am I supposed to do to clean/preserve it? Also, my wife found what we think could potentially be a fossilised log? It is very heavy and to our untrained eyes, looks like a log with bark around it. It was quite different from all the other rocks in the area. What do you more knowledgeable guys and girls think? Again, any tips or thoughts on cleaning/identifying it?

Hi Fossil Forum, I'm an amateur collector with a particular interest in petrified wood. I'd love to hear your thoughts on this ring growth detail from a large early Miocene era petrified tree from outside Sukabumi in Indonesia. This particular image is from the top of partial trunk attached to a larger tree. Does anyone know the particular age of this tree (or side trunk) when it was petrified? Can you also identify seasons? I'd love to learn more about petrified tree ring growth. Best, Nick

I keep trying to twist this fossil around thinking it will come out a marine or cetacean (atlas or axis) vertebrae. Something like a rubik cube. Any one recognize a feature? The fossil is L 3.25 x W 1.5 inches .

Miocene ape possibly showing bipedal tendencies described
Miocene_Mason posted a topic in Fossil News
This paper (abstract below) describes Danuvius guggenmosi from the Miocene of Bavaria, 11.62 million years old, around the time great apes started to diverge into lineages which would give rise to gorillas, chimps, humans, and bonobos. The type of locomotion it used is claimed to be a modified form of bipedalism which they call “extended limb clambering.” This would lend a bit more credibility to the idea that quadrupedalism is a derived trait in non-human great apes. It is hot off the presses, and this isn’t the first time such a thing has been claimed, but exciting nonetheless. https://www.nature.com/articles/s41586-019-1731-0 Update: Full paper: https://www.nature.com/articles/s41586-019-1731-0.epdf?referrer_access_token=VDVF2mJ0lVofld8_madjttRgN0jAjWel9jnR3ZoTv0MpMJV7uq1pC2z9TlFLcopWAwsUutKmnIQkQ9UatmGBhFbbK0TqgHY6DOdEwLF7zxg9jcVJzhHgeUec4SXds2t2K54ZcgXJyXyUChehzfQs_nuIO6zLpD5p57osl9HmfIS4CCPmGYQlMcB75-PqvezwQ90kw_MMZRjrQzwrHBa8hpfgpIdXBMsjkAHpBtdH3fgRz0TPA3HiaoFlaXKL4BFUnxXrdJAYVqTlkYjuSHobfCkpECcbjdsp0qnRPEHkBeiR1woxUL-dPJxf9Cc7x8sXO-FNv0I9g7MraGFHHLfT33QN8WUElO7bdoRZOKHUUhw2PVnBJNDGV3WPQnxDhxY5FFg5xP8VmTVeP72XSU-_5A%3D%3D&tracking_referrer=www.smithsonianmag.com- 4 replies

October has not been kind to me health-wise; jetlag, diarrhea, flu, and bronchitis. Still weak and fighting a cough, but a beautiful time to be outside (love the Fall!, just wish the teeth would cooperate better). Typical sand shark spikes, angel shark, drum, and verts (more gravel than sand or shell bits), lots of small teeth, not sure of ID. A few tiger shark teeth (rare for me), a few small, de-enameled makos, a small bonito nose (second small one I've found?) and nothing spectacular or BIG, though more "shrimp coprolite burrows" than usual. I tried new places but the results are about the same (less teeth?) than my older spots.

Newly prepped Tumidocarcinus Giganteus crab, collected by myself
mamlambo posted a topic in Member Collections
I found a really good concretion a few months ago here in New Zealand and didn't want to try prep it myself as I am still very much a beginner. Luckily, @DLB was willing to help me out and did an amazing prep job - both sides! It's by far the best crab in my collection, and very well travelled after it's 24 000km (15 000mi) flight It measures 16cm (6.25") across. I made a video of me finding it, sending it off, and opening it which can be found here: https://www.youtube.com/watch?v=V4cqpVKsOO0 Thanks for the amazing prep job @DLB!
