  1. Gosiutichthys parvus multi-plate

    From the album Purchased/Gift Fossils

    An auction site find - multi fish plate. A school of Gosiutichthys parvus. Green River Formation Middle Eocene Wyoming These are Gosiutichthys parvus. Not 100% sure, but the largest fish on the plate measures about 2.25 inches in length.
  2. These micros came from Eocene, Orangeburg Formation matrix from the LaFarge Quarry in Harleyville, South Carolina. This matrix was given to me by Larry Martin years ago and I just recently had the time to finish searching it. The matrix was very fine, what fell through a 1.5 mm sieve. It was very time consuming to search the matrix because of the small size. I usually only sample matrix this fine but looked through all I was given because it contained both oral and rostral sawshark specimens. I found 14 oral and 6 rostral sawshark teeth (Pristiophorus sp.). One oral (1 mm) and two rostral teeth (2 mm & 3mm)are shown below. Sawshark teeth are very rare from the East Coast of the United States. (Note these are sawshark not sawfish) I found a good number of Mustelus sp. (1 mm). Mustelus are actually pretty common, especially in a lot of Miocene formations, but aren’t collected very often because of their small size. I found a single Dasyatis sp. (1 mm) A nice Heterodontus juvenile anterior tooth (1 mm) Lots of catshark teeth (1 mm – 1.5 mm) Lots of different fish teeth (Note the fish teeth are in a 1 inch diameter gem jar) Lots of placoid scales (less than 1 mm) and a few ray dermal denticles (1 mm). Placoid scale Dermal Denticle Marco Sr.
  3. Ive just sold two crabs and one nice fish and made a bunch of money's and I also had some freinds coming over. Once they left I started yet another fossil crab fossil. Whilst digging a hole in the concretion cause i wasnt sure of ventral or dorsal I was thinkin of another fossil hunting adventure and simply was not paying attention because of the excitement of all that money and friends and did a real number on messing up this crab carapace. I was absolutely shocked!!! Then was disgusted with myself. This is the most desaterly 'ding' ive put onto a crab carapace!!! Bar none!!! I can also now tell that this crab is sittin off center of the concretion. Not a good thing!!! Most of the crabs i do, do not make it into my collection, but thats besides the point. Having to 'fix' a big screw up really bothers me even though this crab more than likely has problems. Fossil preppin is for fools!! For losers! Sorry, just mad at myself, but this most assuridly lets you see that even the "Great RB' is not quite perfect. Ha!!! At least I can crack myself up. Still hurts though. RB
  4. Tiny Oddity

    I have this echinolampas appendiculata from the eocene , Castle Hayne Form., of North Carolina that has a strange tiny ( 4 mm dia.) critter riding along. It has tubercles like an echinoid, but in some ways looks like a barnacle or maybe sponge ? Any ideas ? Thanks
  5. Ostrea, but what species?

    Hi all, What species of Ostrea do you think this is? My first thought was O. edulis, but I am wondering if it maybe isn't O. ventilabrum after all. In fact, how exactly can you differentiate the two different species? It was found on the Zandmotor, Netherlands. Most of the shells found here are (apart from modern) from the Eem Formation, Eemian, Pleistocene; 120'000 years old. And it would be this old if it is an O. edulis (which is a very common species). But maybe it is the rarer Eocene O. ventilabrum? I know that they do occur here too, but I never know how to tell them apart from O. edulis. Looking forward to hearing your answers! Max
  6. Crassatella ponderosa (Gmelin 1791)

    Shell preservation.
  7. Gitolampas oviformis

    One of the few items in my collection which was not self collected. Given to me by another forum member. The location this was collected from in now paved over and has been closed for close to 2 decades. A rare find even at that site. Once known as Santeelampas oviformis, Kier (1980) assigned this to his early Biozone. Known from only a very small handful of sites in North and South Carolina's Castle Hayne, Warley Hill and Santee Limestone Formations. One of the intriguing things about this echinoid is the lack of matrix inside of the test. You can see this in the last photo of the periproct. The light inside is what is seen through the paper thin test.
  8. Hello all, I stop collecting shark teeth from the cenozoic. I offer all my shark teeth for trade here. There are 3 different location. -Antwerpen, Schelde. Collected in 1970 (not by me) -Balegem. Collected in 1986 (not by me) -Steendorp. Date not known. There is one Megalodon (Steendorp). It's about 8 cm and has all serrations. There is some damage at one side. Steendorp is a closed location were fossils from the Neogene were found. Next there is about 4,5 pound of Balegem shark and ray teeth. These were collected in 1986. There are a couple of Otodus teeth (at least 3 complete), I heard these are pretty rare, but most are from Striatolamia macrota. The biggest one is over 2 inch. This is also a closed location where fossils from the Lutetian (middle eocene) were found. Many complete teeth altough there are also broken teeth in it. No junk. The last location (Antwerp) includes about 1,1 pound of teeth that were found in the Schelde in 1970. Most teeth are broken but there are some nice small ones in it (Notorynchus, Hastalis...). (No pictures yet). At last I will throw in some teeth from Cadzand/Breskens (The Netherlands). There are waaay to many teeth to take pictures of every single one of them, so I just took some pictures of some. If interested, Pm me and I will send you more pictures. I know the pictures aren't the best, but I don't have a camera and my smartphone don't want to cooperate with me. I'm looking for: -Fish -Anything insect -Anything dinosaur (no chunkosaur) - Fossils from Liaoning or similar locations in China - Trilobites - Permian/ Triassic reptiles (teeth,jaws, bones etc.) - Anything I don't have from the KemKem Beds. -All shark teeth that are at least as old as the Cretaceous. - Fossils from the Eocene of Morocco. - ...

  13. Quercus petros leaves?

    I found a group of leaf fossils, could not resist them. I know they are from the Green River formation of Utah; Eocene age. Are these Cuercus petros? I've looked over a lot of specimens from that area; these SEEM to match. (Except for the first photo.... not sure WHAT that one is! Leaves.... but from what?) I think I am developing a plant fossil obsession! On another note - While I LOVE to hunt fossils, I DO buy specimens, so that I have an in-hand model to use for comparison and learning!!!!
  14. Hi, I thought I'd share some of my best finds from what has been a brilliant start to collecting in 2018! The Isle Of Wight has been hit by heavy storms, with torrential rain and gale force winds, numerous times over the last month or so. This has caused some serious erosion and slipping to the soft clay cliffs and foreshore of the Bouldnor Fm. and the coast has been highly productive. I've made some of the best finds of my fossil hunting "career" (if that's the right term for it), including some very nice large mammal finds that I have dreamed of coming across for a while now. 1. The partial cranium of a mammal. This is without a doubt one of my best finds. I collected it ex-situ from the foreshore and at first thought I was looking at a large piece of fossil wood, which are common in some of the fluvial and freshwater horizons of the Lower Hamstead Member. Luckily I spotted the cancellous bone texture, and quickly realised it was a large piece of mammal skull. The cranium is essentially the left portion of the brain case with the parietal bone, part of the frontal bone, jaw articulation surfaces and saggital crest with scars from the temporalis muscle. The brain case is filled with sediment and Viviparus gastropods, which may be the culprits for the extensive mollusc bore marks on the parietal bone. There is also a Stratiotes seed in one of the gastropod shells indicating the skull was deposited in a shallow (less than 6.5m deep) freshwater pool, probably already broken. Skulls like this are incredibly rare, and I've heard that it looks like it was probably out on the shore for just a couple of hours! As usual with my big or unusual finds I took it straight in to Dinosaur Isle Museum where it's currently on loan for preparation and identification in case it's an important find. I believe it may be something like an Anoplotherium although I'm not sure. 2. Partial Bothriodon mandible. This is a really cool find that I've always wanted to come across! Bothriodon is an abundant part of the Post-Grande Coupure mammal fauna, arriving in Europe and Britain around 33.6 million years ago from Asia. This was facilitated by the Oi-1 glaciation event in Antartica lowering global sea levels and opening up several migration routes from Asia into Europe for a myriad of immigrant taxa. The habitat of the early Oligocene Hampshire Basin was ideal for the proposed lifestyles of anthracotheres (low lying coastal plain with wetlands, lakes, and open woodland), which along with a preservation bias, makes Bothriodon the most common large mammal encountered. I found this jaw in two pieces, 14 days apart and 5m from each other in a mudflat at low tide. The bone is heavily crushed and has P2 - M3 in-situ, although P1 is missing (possibly pre-fossilisation) and I still haven't found the other jaw section with the M2 (fingers crossed it'll turn up one of these days!). I think the jaw washed out of the Upper Hamstead Member during this winter's storms and smashed into several pieces which were subsequently scattered over the immediate area. (P1 to M1 section found 14 days after the M3)

    5x4.5cm. From the Eocene Inglis Formation at Inglis, Florida. Thanks to Dan Woehr for the gift!
  19. Carcharocles Confusion

    Found on N Topsail Beach, NC, in October of 2015 (not long after a dredging and sand replacement project). Longest edge is 6 cm. Various "authorities" have offered conflicting id's. I don't have many fossils worth showing anybody and I'd like to be able to tell visitors definitively what it is. I did read the various threads on this topic in the forum and looked it up in other sources, as well. However, I found researching Carcharocles auriculatus vs Carcharocles angustidens much like watching a pack of hound dogs turned loose on a truckload of rabbits released in the forest. Would appreciate opinions from those knowledgeable on the current theories regarding this (apparent) debate. Or is it just evolution of opinion?
  20. Serratolamna koerti ?

    I found this a while ago on a spoil island in the Cape Fear River in Wilmington, NC . I believe this is mostly Castle Hayne formation, eocene. Tooth is 1 1/4 inches long. Missing a side cusp, no serrations, no nutrient groove that I see . Is this a Serratolamna koerti ? Thanks for your help.
  21. Diplomystus prep

    Been a long time since ive prepped out any fossil fishy's. Here is one I started today. This one is from the 'bottom cap'. Just below the 18 inch layer. gots a long ways to go but got a good dent in it. So far the lower jaws are where they are supposed to be, the tail seems to be there, but the really tuff one is the anal fin? We'll see. I have to get my son to cut lots of rock off so it will fit in my air abrasive cabinet? Then i just have to hope that its not to cold to work? But so far, lots of fun!!! RB
  22. Shell preservation. Missing a little on the left.
  23. Complete shell preservation.
