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.- 11 replies

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?

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 .

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

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!- 13 replies

Ancient Bones, old bones and husband Dennis, along with Annie the rat terrier were joined by my brother and his wife on a trip to the Carolina coast. All of the following fossils were beach finds. I am posting for Ancient Bones and myself. Here are some of our favorite finds. Ancient Bones found this great alligator osteoderm. and several of these Burrfish mouth plates. She also found nice ivory fragments like this one. These are some of Ancient Bones various ray crushing teeth including Aetobatus, Plinthicus stenodon, and Myloibatis. These are Ancient Bones shark teeth. Sand Tiger Great White shark tooth an assortment of smaller teeth We are not sure which these are. Please jump in and help Ancient Bones ID these. We kept this item as we considered that it may be a periodic... @Boesse continued in next reply

I stopped at Lake McConaughy (near Ogalalla, Nebraska) on my way out to Colorado and picked this (along with some nice burrow casts, probably clam) from one of the beaches. I’m not very familiar with the fossils in this part of the state and wondered if anyone could help me with who this chunk of bone may have belonged to. I know it’s a stretch to id this considering how little of the bone is there and the lack of either end, but any help would be appreciated.

Dolphin tooth 16mm. Burdigalian OMM Miocene Found near Billafingen, B.-W., Germany -
Or something else? I know that I've seen this kind of tooth before, but for the life of me I just don't seem to be able to remember where. I found it at my shark tooth spot in the Miocene Burdigalian. It measures 16mm. from the bottom of the root to the tip.

In the last issue of our German magazine "Fossilien" there was an interesting article about a site right in the middle of my stomping grounds of which I was not aware. My area is practically all Jurassic, but this site is in a basin which exposes a middle miocene maar lake, so the other day I figured I'd go have a look for some gastropods, plants and bivalves. Sorry, I forgot to take my camera again. The area is not all that big and I was able to walk over and around the fields on it within a few hours. There were a lot of loose stones to inspect, but unfortunately there were hardly any fossils to be found despite the fact that I did an awful lot of hammering. At least I came up with a couple of little freshwater bivalves and funnily enough, although this was not mentioned in the description, an ammonite on a late Jurassic limestone block. Pisidium sp. on the left. Can't identify the other one. Any ideas? Trimarginites sp. I still had a couple of hours to spare, so I decided to take a walk over one of my favorite fields near Geisingen and this time I had a bit more luck. Here they are all prepped. Garantiana sp. Prorsisphinctes pseudomartinsi

A new cetacean-related paper is available online: Leslie MS, Peredo CM, Pyenson ND. 2019. Norrisanima miocaena, a new generic name and redescription of a stem balaenopteroid mysticete (Mammalia, Cetacea) from the Miocene of California. PeerJ 7:e7629 https://doi.org/10.7717/peerj.7629 A redescription of "Megaptera" miocaena was long overdue, as with other Miocene rorquals previously assigned to Balaenoptera and Megaptera, and the paper by Leslie et al. shows that this taxon is far more primitive than other balaenopteroids. The name Norrisanima is tongue-twisting because anima means "living" in Latin, and the genus honors the late Kenneth Norris and his son, Richard.

Miocene sites around St. Josef, Styria, Austria (10/01/2019)
FranzBernhard posted a topic in Fossil Hunting Trips
Hello, at Tuesday, 10/01/2019, I made my first visit to the area around St. Josef, Western Styria, Austria ("Florianer Schichten", Langhian-Miocene) since about 11 months. I checked out 6 sites in 5 hours, three of them were made public by me 2-3 years ago: Fuggaberg-3-a Fuggaberg-3-b (This one was also published in a local journal 2 years ago.) Hoellerkogel-4 Bramberg-1 All sites had easy surface pickings of small fossils from debris. Outcropping sediment with fossils is exposed in 5 of them, in one you have to dig a little bit (Fuggaberg-3), but its still easy going. I guess I have collected and seen about 40 mollusc species within these 5 hours. So, the situation around St. Josef is still very good (if you like miocene molluscs and small fossils, though ). I am starting with: Fuggaberg-3 Two fossil-rich outcrops are located in a very small creek, about 15 m apart (W and E, 1st row, left). At E, only the fossil-poor overlying sediments are exposed at the moment (1st row, right, the red object is about 12x6 cm large), but digging in the debris below (2nd row, right) yielded some fossil-rich matrix specimens. You can see the yield of this 10-minute dig in the pic of the 3rd row, right. Of special interest are the two small fossils lying on oyster shells (coral and muricid). The debris 1-3 meters below the outcrop contains many loose fossils, eg. Granulolabium bicinctum (2nd row, left) or Terebralia bidendata (3rd row, left). Nearly the same situation at W, only overlying sediment is exposed (4th row, left). In the debris below, below the red object, many small fossils are lying around (4rd row, right). You can see Granulolabium bicinctum, Terebralia bidendata, Turritella partschi, Sphaeronassa shoenni, Acanthocardia paucicostata and a bi-valve Anadara diluvii; only the last one is not lying at its original position but was put there for photo purposes .
