  1. Found this odd 9" long jaw-like fossilized bone in a small creek within the Yorktown formation in Virginia between the York River and I-64. It is atypical of the Baleen Whale and Ice Age mammal bones I have found in the same area. Any help with identifying this specimen would be appreciated.
  2. Hi everyone! Little over a week ago I recieved some new bags of microfossil matrix and this time there was a bag with material from the Lee Creek Mine, Yorktown Formation, Aurora, North Carolina, USA (Miocene, 14,5 mya) This material is quite rich in shark teeth as I found little over 90 shark teeth in it. I have photographed a couple of them already and posted them in my microfossil topic. But since I doubt I will get many help with the identification of the teeth there I am going to repost the first batch of teeth here (I apologize for the repost admins) and upload the rest of my finds from that material in this topic from now on. I have tried to ID some of the teeth with the help of the website Elasmo & the paper "Geology and Paleontology of the Lee Creek Mine, North Carolina, III by Clayton E. Ray and David J. Bohaska", but I feel like my eyes aren't enough trained yet to distinguish enough to make proper ID's on all of the finds, so I not all ID's will be a 100 % correct I am affraid. Here are some of the first teeth I photographed. I would be gratefull if some of you could help my ID some of the teeth of verify /correct some of the ID's I have come up with. If the photo's aren't clear of good enough, just let me know and I'll try to make some more/better ones. Thank you in advance! The first tooth which is by far also the favorite in the bunch: Tooth 1: a Sphyrna zygaena tooth? Tooth 2: a chunk of Galeocerdo sp. tooth Tooth 3: another Galeocerdo sp. tooth Tooth 4: This one is a tooth which I have a hard time identifying as I feel it has a lot of features that return in different teeth. Physogaleus? Sphyrna? Loxodon? Tooth 5: another I haven't managed to ID yet. Tooth 6: Carcharhinus sp. Tooth 7: could this be Negaprion sp.? Tooth 8: Tooth 9: Scyliorhinus sp.? Tooth 10: Megachasma sp.? Tooth 11: Megachasma sp.?
  3. Hi everyone I just ordered some more microfossil matrix samples, most of which are rich in shark teeth. But I would like to know what to expect from the matrix, which means I am looking for websites of pdf's which describe the species from those locations. The first is from Lee Creek Mine, Yorktown Formation, Aurora, North Carolina (Miocene), I did find an ID section of Lee Creek teeth on elasmo.com but it wasn't extremely extensive. The second sample is a shark tooth rich Limestone Block (which still needs to be disolved) from the Mesaverde Formation, Rollings Member, Colorado (Cretaceous). If anyone has some pdf's of info sheets that could help with ID'ing the finds, I would be more than grateful! Thank you in advance!
  4. Found this in the Yorktown formation in Virginia. Not sure which bone this is from a Baleen Whale. Any ideas?
  5. A new paper is available online: Bisconti M, Bosselaers MEJ. 2020. A new balaenopterid species from the Southern North Sea Basin informs about phylogeny and taxonomy of Burtinopsis and Protororqualus (Cetacea, Mysticeti, Balaenopteridae) PeerJ 8:e9570 https://doi.org/10.7717/peerj.9570 The description of a new Protororqualus species from the Zanclean of the southern North Sea basin as well as North Carolina comes months after the publication of the PeerJ paper describing a new Archaebalaenoptera species from the southern North Sea, furthering making clear that the geographic distribution of extinct rorqual genera is widespread like modern rorquals. This paper also re-assesses the genus Burtinopsis, agreeing with Steeman (2010) in treating this genus as dubious (of the material included in the hypodigms of both Burtinopsis species, only 11 can be safely regarded as belonging to Balaenopteridae, of which RBINS M 688 and M 702 mostly closely resemble the earbones of Protororqualus).
  6. Strange bone pattern

    I found this shard of bone on the York River in the Yorktown formation, and the pattern on one side is curious. I’m wondering if anyone has seen this, or if it’s a diagnostic texture? Thanks for any help!
  7. York River prize

    Just one tooth from the York River in Virginia this weekend... but I’ll take it!
  8. Thoughts on This?

    Hello! Anyone have any ideas? I believe we are looking in the Yorktown Formation in Virginia. Found right next to Lots of Chesapecten Shells. It feels like stone but is a very strange shape. Almost all the stone coming out of the layer is pebbles and somewhat rounded.
  9. These shells all look similar in nature except the last one, pictured by itself. Any way to identify, specifically? Thank You! Freshwater Creek, very slick light brown clay bottom which is blue grey once penetrated and dug. Also sand.
  10. Possible Toe Bone

    Good evening, i found a bone that I believe to be a toe bone of a mastodon or mammoth. The bone was found in the Neuse River in Craven County, NC. Thank you in advance for assistance in identifying this piece.
  11. Bone ID request

    Good morning, second post today! I found this bone in the Neuse River in Craven County/ Eastern NC. The shape of the bone is throwing me off on my google search. Can anyone identify the bone? Apps size is 3.5 inches by 3 inches. Thank you
  12. Bone ID Request

    Good morning, I am requesting help with ID on a bone I found in the Neuse River in Craven County in eastern NC NC. I have searched google but not able to find a bone of this shape. It measures 2 inches by 2.5 inches. What throws me is the twist in the bone, probably a result of excessive wearing in the River. Thank you
  13. Globidens alabamaensis?

    While collecting at a location in SE Virginia which produces a mixture of material from the Eocene Nanjemoy Formation and late Miocene/early Pliocene Yorktown Formation, I was shocked to find what I believe to be a cretaceous Globidens sp. anterior tooth fragment. My only explanation for this would be that it must have been redeposited into the Eocene beds and finally exposed with rest of the material. The texture is classic Globidens. The only other species with a slightly similar texture found within these formations (though still markedly different), would be Squalodon sp., however if the tooth were more complete it would clearly prove to be hollow with a conical interior consistent with squamates like mosasaurs. The fragment is approximately 7/8" x 1/2". This is the first bit of possibly cretaceous material I have found from these exposures, so it would be quite interesting if the general consensus is a Globidens sp. Your thoughts would be much appreciated! Thanks, Ash
  14. Possible Mastodon Tooth Fragment

    Good afternoon, I went out to the beach by the old scout hut at Cherry Point and found several interesting items. I believe two of the pieces are fragments of a mastodon tooth. I will try to post as many pictures as possible. Thank you
  15. I haven’t been keeping any Ecphoras that I find because I have all I want but this one looked like it could be pretty big. Turned out not to be very big but big enough to be interesting. It was found in a river outcrop with a little bit exposed. Normally small ones can be easily cleaned with a toothbrush and soapy water but bigger ones tend to have cracks. This one had plenty of cracks and rotten spots that made it fragile. It had to be preserved with vinac. Here are some pics during prep.
  16. Posterior Megs?

    Hi all, the other day I went out hunting found some really cool stuff, which I'll post soon, but I find these 3 interesting teeth which I think are posterior megs, though I think one (smallest) is more likely than the other two. They were found in Havelock NC.
  17. Found this in a location known as yorktown - I know part of the formation nearby is rushmere member zone two, but I am not sure if the place I found this would also be considered as such but it was found among similar items, tube worms, ecphora quadristata, diadora and slipper shells. I've found a few pieces of this shell before but they have not preserved well so I'm very excited to finally have a whole specimen of this unique and beautiful shell and anticipate getting an exact ID on it! Is this a Margaritaria abrupta? Let me know if additional photos are needed to aid.
  18. Aurora NC bone to ID

    When I stopped by the Aurora Fossil Festival a few weeks ago I was able to spend 1/2 hr or so sieving at one of the piles that are brought in for the festival. The piles include Pungo River Marl (lower Miocene) and Yorktown Formation (lower Pliocene) as well as possible Chowan River Formation (late Pliocene) and James City Formation (Pleistocene) material. Besides an assortment of the usual small shark and ray teeth, I found the following bone. Any suggestions as to a possible ID would be appreciated. Don
  19. Tiniest Ecphora Ever

    Last week on a trip to the Tar River I brought home several decent sized Ecphora quadricostata along with an assortment of other gastropods and bivalves. This was on the same trip I found the Gannet ulna. While cleaning matrix from one of the larger ecphora's today, I found this teenie tiny ecphora quadricostata. It is 13.6 mm (.53 inch) long and 11.4 mm (.45 inch) wide. Here it is in a standard 4.35 inch by 3.35 inch riker mount.
  20. North Carolina Pliocene Bird Bone

    I found this bone today in Edgecombe County North Carolina on the Tar River, upper Yorktown Formation, Rushmere member. The area is well known for Chesapectens along with other bivalves and gastropods. I looked at the Smithsonian publication, Geology and Paleontology of the Lee Creek Mine, North Carolina, III. Miocene and Pliocene Birds from the Lee Creek Mine, North Carolina. Storrs L. Olson and Pamela C. Rasmussen. Issued May 11, 2001. After searching the many plates I found one that is a pretty good match. The proximal end of right ulna of Morus peninsularis. a Gannet. I am looking for your opinions on this. @Auspex It is plate 14 page 333. I would love to have this positively I.D.'d. It was found in the formation, partially exposed and 2 pieces. They fit together well. Overall length is 144.4 mm or 5.68 inch.
  21. Can anyone help I'd this partial gastropod? Found it in the pliocene Yorktown Formation. It appears to have been pretty big in life. Thanks!
  22. Miocene horse tooth?

    I found this in a river in Virginia -- miocene Yorktown Formation. Does this look like a miocene horse? Maybe it's a modern horse tooth that got washed into the river? Any help from the experts appreciated! Matt
  23. Possibly Astrangia sp a.JPG

    From the album MY FOSSIL Collection - Dpaul7

    Coral Specimen - possibly Astrangia sp.? SITE LOCATION: Yorktown formation Beaufort County, Aurora, North Carolina TIME PERIOD: Pliocene age (5.333 million to 2.58 million years ago) Data: Unknown genus, possibly Astrangia sp. Corals are marine invertebrates in the class Anthozoa of phylum Cnidaria. They typically live in compact colonies of many identical individual polyps. The group includes the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of myriad genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in length. A set of tentacles surround a central mouth opening. An exoskeleton is excreted near the base. Over many generations, the colony thus creates a large skeleton that is characteristic of the species. Individual heads grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously over a period of one to several nights around a full moon. Kingdom: Animalia Phylum: Cnidaria Class: Anthozoa
