  1. Three! Identical mystery bones

    Update: we now have three samples of this fossil. These really perplex me. They have almost mathematically straight, shallow, ridged channels on one side. No serrations on the edges. i had been grouping them with my sting ray and skate fossils, but just realized that I haven’t seen any pics that look like these two. Is that what they are? Or is it something more... nefarious? Both are from Aurora. Thanks frank
  2. Hi, I've collected this fossil on a beach near Balchik in Bulgaria and have wandered what it is. On the same beach I've also found small parts of bones and a partial vertebrae. Since there have been previous finds from Deinotherium bavaricum , Trilophodon angus-tidens and Choerolophodon pentelici in the region I was pretty exited that I've found a part of a tusk or one from a baby, but I am really not sure what exactly the fossil is. Please if you have any good guesses for the origin of the fossil please let me know.
  3. Shark Week on the Discovery Channel starts tonight and one of the shows is about C. megalodon. It's on at 8pm Eastern and Pacific time.
  4. GMR find that has me clueless

    Hey-oh! I found this while at GMR and I'm clueless as to what (if anything) it is. I've been though my fossil books and online but the curvature and the indention marks have me puzzled. I've not found something like this before. My luck it is a weird curious rock.. if it is, I'm just going to imagine it's a meg eye lid or something hahaha As always, I welcome your thoughts and appreciate you all Steve
  5. Hello! Help please with identification of these fossils. I understand that a lot of them are not identyfieble, but may be not all :-) Thanks in advance!
  6. Decapod claw or pseudofossil?

    99% sure this is just a rock, but the shape just keeps me wondering... Found along the beach of Stratford Hall in Montross, Virginia on 7/6/19. Any thoughts?
  7. Found these imprints in the island of Rhodes (Greece). The age of the cediment according to geological maps of the area is upper Pliocene to lower Pleistocene. The units on the scale are cm. I wonder if my assumptions about pine cones are correct (even considered cycad cones) having read about pine cone specimens being found on the island. Would be really happy if someone could pinpoint the species from the shape of indentations - in the first image which is the most detailed there appears to be a small hole in the center of what I suppose are the cone scales. This can also be seen in the second image, though the structure is in worse shape probably due to being exposed for a long time.
  8. Bivalves from Madagascar

    Hi everyone, I went to a small rock shop some time ago and bought these three fossil bivalves. Unfortunately, the only information they had on them was that they were from Madagascar. More importantly than the species, I'd really like to find out a more precise location and age (including formation) for them. There were 6 shells available in the shop (all clearly from the same location). 4 of them were #1, then #2 and #3 were unique. #1: I think it's something from the Mactridae family.
  9. Fish teeth? Any ideas?

    We have found these on the same samples where we found some shark and ray teeth... it looks like teleost teeth?! Grid scale (5 mm) Any ideas?
  10. Ray teeth? Pt2

    I need help identifying this piece of dental plaque from a ray. Any ideas?

  13. I am planning to head over to Green Mill Run in North Carolina this coming weekend (6/16/18) to do some hunting. I have done a little research but haven't come across too much. I know there are lots of shark teeth, as well cretaceous, paleogene, and neogene fossils. I was curious if anyone has been, and if so what some of the hot spots might be. Not sure if I should head closer to the main river, or stay within the smaller channels to search. Will probably do some visual hunting as well as sifting. Any information would be greatly appreciated!

    FLYKOwswish this article has some bearing on the following issues: Mammal biochronology,the precise timing and/or speed of the G(reat)A(merican)B(iotic)I(nterchange),it contains some remarks on mammal taxa(however brief), magnetostratigraphic resolution from the Miocene to the Pleistocene, the closing of the Panama isthmus, and the possible diachroneity of mammal taxon appearances. There are NO taxa illustrated,and the authors' (infrequent)use of "heterochroneity " is unfortunate . If you have Woodburne(2012): this might be up your alley I liked it,but I'm weird that way
  17. I have a coprolite that has me somewhat puzzled. It was found in a river in South Carolina and dates Miocene-Pliocene. I picked it up at the Tucson Gem Show because I thought it resembled some east coast coprolites with longitudinal striations/furrows/grooves that @MarcoSr posted a while back. Now that I've looked at it for a while and done a little prep work, I'm not so sure the grooves are sphincter related. There are intestinal muscle marks visible on one side, but they don't seem to match up with the grooves. The grooves were filled with sandstone/limestone. I left matrix in the deeper portions to preserve the integrity of the specimen. Across from the grooves are what look like puncture marks. My first thought was that they were clam borings. However, they do line up with the grooves in question. Now I'm wondering if these could be tooth marks as well. Under magnification, I noticed smaller tooth marks and an impression that I can't figure out. My imagination is now getting the best of me, and I'm seeing food chain activity. I'm seeing a big fish nabbing a small fish that was nabbing an invertebrate that was feasting on feces. Do you think the larger grooves and holes could be tooth marks? Does anyone have any idea what could have left the impression? The only thing I could think of is some sort of mollusk. Love your thoughts on this. @Carl

  19. I thought I would bring in the forum on a difference of opinion among a few collectors. Attached are views of a specimen identified as a Metaxytherium tusk (late Miocene, Bone Valley Formation, unnamed phosphate mine, Polk County, Florida) by one experienced Florida collector and another collector familiar with a range of marine mammal fossils. Two other experienced Florida collectors leaned toward an ID of whale tooth. The specimen resembles one in Domning (1988: p. 409, fig. 7) which was identified as a Metaxytherium tusk. The specimen in question is straight like a tusk with an enamel-coated crown with a constriction toward the tip as in the figure. I've looked for a similar specimen labelled as a whale tooth in various publications (Richard Hulbert's "Fossil Vertebrates of Florida; the Lee Creek volume that covers mammals, etc.) but couldn't find one. Metaxytherium was a "sea cow" or dugong relative that lived during the Miocene - a time when sea cows were more diverse and widespread than they are today. The Florida collector who thought it was a Metaxytherium tusk pointed out the enamel texture and its laterally-compressed overall form was the same as a tusk. The other Florida collectors didn't point out any particular feature to count it out as a Metaxytherium tusk - just didn't look right to them. I can understand having difficulty articulating an overall impression. Those two guys know Florida fossils so I respect their opinions. I'm interested in reading what other collectors think - especially all the Florida/Bone Valley collectors out there. I'll try to get a scan of the figure in the Domning article and attach it - couldn't find a pdf in a quick search. Thanks, Jess Domning, D. P. 1988. Fossil Sirenia of the West Atlantic and Caribbean region. I. Metaxytherium floridanum Hay, 1922. Journal of Vertebrate Paleontology 8:395–426.
  20. Hi all, I have been having trouble finding a good guide to use in order to ID fossil seashells (mainly gastropods and bivalves) of the Neogene-Quaternary of Western Europe (mainly Belgium/Netherlands). So, I'm turning to you guys: does anyone of you have a nice up-to-date website/online paper that I could use in order to help me ID all of my different seashells? Preferable with clear photos/drawings of the different species. Thanks in advance! Max
  21. Possible skull material, Capitola

    Hey everybody! It’s been a handful of years since I posted on here, but I was in Capitola recently and I picked up this fossil. The low tide wasn’t very low that day, (3.7 I think?) so...not the best day for collecting, but I drove in from AZ so I went anyway. On my way back to the car (giant toddler in one arm, heavy bag of fossils/shells/rocks in the other, I tripped over this guy. I didn’t get a chance to really look at it but It looked like it might have had bone in it so I threw it in the bag thinking maybe it was a partial vert or something. But now that I’m home and unpacked and have had a chance to actually look at it, it seems like it might be some part of a skull? Does that seem right? (Can you tell I mostly stick to invertebrates? Ha!) Also, sorry if this picture ends up being huge this is my first time posting from my phone and I can’t figure out how to change the size. It will only let me attach one photo, so I’m assuming the size is the issue. thanks in advance for your help! Edited to add Capitola makes this Purisima Formation, Neogene Period so Miocene/Pliocene. Marine fossils. (Forgot all the important information!)

  23. Here are a great white (Carcharodon carcharias) and an Aetobatus tooth from a site other than the main one(s) around Sacaco from which we have seen teeth (or perhaps an example of what was found on the surface). This Aetobatus tooth might be the coolest-looking one I have - rather large with deep color and some apparent microfossils embedded within the patch of attached matrix. I am starting this thread because there was a question in another thread about the range of preservation seen in fossils from the Pisco Formation, Sacaco area, Peru. We tend to see mostly lighter-colored (blue or pink or blue and pink), well-preserved great white teeth with great serrations but there were also some teeth on the market that were more worn and duller in color yet shiny from that wear. They appear to be more mineralized too. If you have similar Peruvian shark teeth, feel free to post your photos. You can't get them anymore but we can look at some of what was allowed to go before the export ban. I tried to pick up the widest variety of fossils while available. Jess
  24. Hey all - our collections manager and I busted our tails off yesterday trying to get everything ready for the Aurora Fossil Festival on Saturday in Aurora, NC. We're going to have a table for the Mace Brown Museum of Natural History (CCNHM), our museum at College of Charleston. We've got some neat casts on display as well as a couple of cases - one is a case chock full of fossils from Folly Beach, SC, and the other is a case full of Miocene and Pliocene odontocete ear bones from the Lee Creek Mine. If you're attending, be sure to bring marine mammal fossils with you for identification - or just to show off and make us jealous! We'll be in the community center sandwiched between tables for the Smithsonian and the North Carolina Fossil Club. We're looking forward to seeing you there! Lastly, we're also looking for marine mammal fossils from Belgrade Quarry to add to our collections as part of ongoing study of Oligocene marine mammals from the southeastern USA. Teeth, earbones, and skull fragments are not common at Belgrade but several critical specimens have already been donated. With a few more specimens, I will be able to put together a paper on the marine mammal fauna of the Belgrade Formation. Hope to see you there!
