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 .

It feels good to get back to river hunting, slightly early this year. My hunting friend found this bone and asked if I could get an ID. There seems to be some features that possibly identify the "type" of bone (humerus, scapel, etc) versus which animal. It is 3.2 length x 1.1 height (inches). Found in the Pleistocene - miocene mix that is the Peace River. However, most of the associated fossils were shark, fish or marine mammal (porpoise earbone & verts), so marine is a possibility. ALL comments & suggestions are greatly appreciated. Jack

This weekend family had to drive to Maryland for my son Dylan's Marching Band competition in Annapolis. We drove down Friday evening after I got out of work. The crazies were out in full force during the drive down, but we managed to arrive safely despite the reckless driving that we witnessed. Dylan's school did not perform till 6:30 PM Saturday evening, so the plan was to do a hunt at Brownies for a few hours then meet my parents for lunch, then go to the Naval stadium and watch the other schools perform until my son school performed. After a rather good breakfast at the hotel we headed to Brownies. We were staying in Bowie, so we were only about 35 minutes away. When we arrived around 8:30 there were about 8 cars in the lot. We got our gear and headed out. Originally the forecast was calling for Full sun and a high of 85. So I was expecting to roast while out there. Instead it was overcast with a nice breeze, so we stayed cool the whole time we were there. There was a fair amount of people on the beach already, slowly working their way around to the cliffs. Low tide was set for around 10. The level was already decent when we got there. I noticed alot of trees were down since I had been there last which was a few years ago. Because I had my family with me, I wasnt sure how far down we would go. Once we got a little ways around the corner we began some sifting. I won't bore you with all of the petty details. But I will say that the finds were mostly small and broken. That being said, I think we all had a pretty good time. The weather was nice, moving around the debris was not too bad, and the surrounding was peaceful. My wife made the best find of the day with a decent, cetacean tooth. I was a bit jealous. She found it by digging deeper into a spot that I had already dug. It is different than the other cetacean teeth that I have found myself or have seen come from there. Devin found a few small teeth and some shells. He also grabbed a crab claw, horseshoe crab carapace and fish vert, all which are modern but he didnt care. There where alot of dead horseshoe crabs for some reason. I myself found small teeth, bone fragments, and stingray plates. We stayed till around noon then had to get going so we could meet my parents for lunch. On the way back I could not believe the amount of people back at the main beach there looked to be 100, all of which were searching with sifters! Any ways we ended up going to Fat Boys Crab Shack for lunch. The food was surprisingly good considering the outside of the building was not much to look at. Then we headed over to the Navy Stadium and watched bands perform. After my Son's school performed we had to head home. We didnt get back till 2am. Needless to say I am exhausted today. We found out later, that his school won the competition for their section and for overall. So we are pround! Here are my finds.
