A quick sketch I did.

This is one I’m not really sure about this vertebra, or this leg bone?... both are very heavy for their size!

To me this skull looks canine, but not quite sure. Please have a look and let me know what you think?

Hey everyone! I've been offline for a very long time (too long ), but I'm finally back in the fossil game! I celebrated the start of the summer vacation the right way with quite a few hunts in Antwerp, and those hunts didn't disappoint When in Antwerp I especially look for shark teeth, but we find other stuff as well (bones and teeth of mammals), which I might make another post about We've also been on a mini vacation to the Belgian Ardennes so stay tuned for more photo spam One of the first finds was this beautiful C. hastalis (bonus points if you spot the matching nail polish ) A pic of how we find them around here Had a lucky day when we found this P. benedeni! Another lucky day when we found this beautiful hastalis And another VERY lucky day when found this beast of a C. carcharias This is the first we've found in all those years of searching for shark teeth!! (they're very rare here in Antwerp) We just couldn't believe our luck with this one Can't wait to explore this location further the coming weeks I hoped you enjoyed this summary of our hunts! Of course we find more teeth than just the 'picture perfect' ones, but these are definitely the highlights Kind regards, Angie

I found this Hemipristis serra tooth a couple of years back. Looking at the left photo, I noted the bite marks, and the fact that the distance between each bite mark was approximately the same as the distance between this tooth's serrations!! So I make up a possible story. This shark was in a feeding frenzy, and under the feeding pressure, this tooth (like other shark teeth) fell out, but before it could clear the mouth area, the shark bit down again, leaving these telltale marks. There are likely other "possibles", but I prefer this one. Now more recently, I have another tooth, in this case a Galeocerdo cuvier, and interestingly it also has a bite mark. Once again the distance seems to be the same between the bite marks and between the serrations on this tooth. I notice a lot. Look at that little hole in the enamel above the bite marks. I have no story that explains that hole. But my story breaks down. The bite marks on THIS tooth seem post _ fossilization not in the enamel, but on the enamel. So I opened this thread to attract others who have bite marks on their shark teeth, and ask some of the shark tooth experts their insights. @Northern Sharks@Al Dente@siteseer@MarcoSr@Plax@sixgill pete

Only example of this king Penguin Skull from this location. Thought to be Pliocene period with everything else we are finding here. Progress is coming along nicely even with a bad break through the top of the cranium. More progress to follow and will have an international scale by next time (small town problems) any my more information on this or similar species would be much appreciated as I have limited knowledge on this particular Penguin. thanks community!

Good evening everyone, I recently did some fossil hunting in the Green Mill Run river in Greenville, NC. The water was pretty low - ankle/shin deep most of the time. I'm pretty new to fossil identification so figured you guys could help me out. Location: Green Mill Run, NC Date: July 2020 Excavation process: Shovel to river bed The first looks like a jaw with teeth indentations. It's about 1.9" (50mm) with brownish coloration. Additional photos below.

Show Us Your Wide Boys! A Thread For The Widest And Fattest Megalodon Teeth
Kurufossils posted a topic in Member Collections
Heres a fun thread for those to show off their widest and fattest looking megalodon teeth fossils in thier collections. I'll set the tone with the widest fat boy in my collection, I don't have digital calipers but it measure roughly 5.4 inches wide by 6.1 inches long. When I close my hand together it looks even more monstrous. Share yours and join the wide boyclub Got the idea while thinking about what the widest megalodon tooth ever found measures, if anyone does know do share in this thread!

Fossils with questions are tossed in a special bucket for thinking about when hunting opportunities start drying up. That time has come. Here a couple: The question: Mastodon or Gomph; I have found Gomph fragments in this location. Another 2 inch fossil, that I almost threw away!! Laying in the sieve, I thought it was unidentifiable bone, but then noted the odd ends. So Bone or Tooth .... If you decided tooth for this 2nd one, you might check out the fossils in this old thread!!! Thanks for all responses.

Hello! I'm a pretty novice fossil hunter, so I look for things that stand out! Recently I found these in a span of about two weeks, I haven't seen anything like them before. The small ones all have a flat/facet on the posterior side, same teardrop shape, and the larger ones look like " big ears" to me, lol. I thought maybe iron concecretions at first, but the small ones look different, in that they are not "round". Ammonites? Reminds me of some of the pics posted of plesiosaur fossils, I have more pics, but the files are too big to post all at one time - I would really appreciate any insight! Fossil pic 3.pdf

Took this photo of an unnamed eschrichtiid from the Pliocene San Diego Formation of San Diego County in March 2019. Until the 2000s, the fossil record of gray whales was confined to the Pleistocene, but thanks to the work of Michelangelo Bisconti, it is apparent that gray whales emerged about the same time as the oldest rorquals (Eschrichtioides was long considered a balaenopterid, but eventually recognized as a gray whale relative).

Balaenid from San Diego Formation of San Diego County, California
DD1991 posted a topic in General Fossil Discussion
The balaenid specimen SDNHM 43880 I photographed at the San Diego Natural History Museum in December 2017 was once referred to Balaenula, but Churchill et al. (2012) recovered it as sister to the bowhead whale rather the right whales and Balaenula, and recent erection of Archaeobalaena dosanko for the one balaenid specimen from Japan previously referred to Balaenula makes clear that the previous referral of SDNHM 43880 was untenable. However, it is unclear whether SDNHM 43880 is a new genus and species or alternatively a new Balaena species due to the cladistic position of SDNHM 43880 obtained by Churchill et al. (2012).

Blog post: The terrible fossil record of sea otters
Boesse posted a topic in General Fossil Discussion
Hi all - in the hopes of attempting to reach a wider audience, and anyone who has collected possible sea otter fossils, I'm sharing the first two posts from my blog "The Coastal Paleontologist" in a short series on sea otter paleontology and evolution. The first one is mostly a bit on sea otter biology, and the second is the first one that really deals with the paleontology aspect. The third (and fourth?) posts will deal with what the limited fossil record can tell us about sea otter evolution. The sea otter fossil record is quite poor, and I'm hoping that some of you may have found some fossil specimens and might consider making them available for scientific study. Anyway, here's part 1: https://coastalpaleo.blogspot.com/2020/05/the-terrible-fossil-record-of-sea.html And part 2: http://coastalpaleo.blogspot.com/2020/06/the-terrible-fossil-record-of-sea.html Part 3: will update as soon as I get it finished! And a teaser - the left mandible of the holotype specimen of Enhydra macrodonta from the Crannell Junction locality right off of Highway 101 near Arcata, California. I spent about 3 years emailing various curators about this fossil, if they had it on loan, and I finally got a response from Dr. William Miller III at Humboldt State University in Arcata that he didn't remember such a specimen existing there. The paleontologist who named it, Dr. Frank Kilmer, who was retired, mailed me a letter indicating that the mandibles had been given back to the private collector (!!!) after the species was published - but nobody at HSU knew their name! One former student did, but would not return my phone calls. I visited HSU in 2008 when I was an undergraduate student and rifled through their teaching collection and found A mandible, but I didn't think it was THE mandible, because of Kilmer's letter, and a misplaced label suggesting it was from a different locality (and therefore a duplicate specimen rather than the original). Dr. Miller indicated I should arrange for the fossils to be transferred to a larger museum, as he was certain that the collection would be thrown in the garbage after he retired! I visited again two years later and set aside all the specimens that should be transferred and secured an agreement from HSU for the material to be transferred to UC Berkeley, which finally happened about five years later. I did not realize that this mandible was in fact THE mandible, or at least half of the holotype (the right mandible is still missing, presumably in that private collection) until I was able to download a much, much higher quality scan of the photographic plates in Kilmer's 1972 paper, and I was able to match barnacle scars between the published image and the fossil. So, we may not have the more complete of the two mandibles, but at least we have one of them, and it is my hope that there is more material in private collections and that more can be discovered in the future.

This bone was found on Azov See shore, Russia. Probable geological age is late Neogene (Miocene or Pliocene). I don't know what this thing is: metacarpal, metatarsal or calcaneus? What a strange hooked process on the proximal epiphysis that is not characteristic of the metapodium? I'd like to get your opinion.

Beautiful day Friday. Sun was shining. Besides sprinkles, rain held off until late afternoon. I am finding interesting fossils. Let me try 2. I have seen similar previously, but never identified. Maybe others have, Then a tooth: Have there been occurrences of Aulophyster like small teeth on the east coast of the US? @Boesse Like I implied, interesting fossils.

Took a trip to purse state park today, got there around 9:30 and the lot was already pretty full. Made our way down the beach to the spots we like to search and my wife found the biggest croc tooth we have found, at least double the size of any of the other ones we have found. A little bit later walking along the low tide shoreline I did a double take and saw the big Otodus tooth pictured. We were able to find a lot of other nice size otodus and sand tiger teeth during our time there. On our way back walking the beach entrance and Wades Bay were packed with at least 100 people and their boats. Overall a great day for hunting!

Hello Fossil Forum, I am a new member looking for guidance and advice. I live in Orlando, 27, and recently have been bitten by the fossil hunting bug. Mainly I am interested in sharks teeth. I grew up going out to the woods of Ocala and around the Withlacoochee and managed to find all sorts of old bones cool rocks and crystal as a kid. I developed quite the collection. I somehow never found out you can find sharks teeth and other amazing fossils in alot of the rivers was going to as a kid. I just got back from a beach trip around venice/manasota key and found a bunch of small sharks teeth. That prompted some internet searches and then some obsessive research when I found out the extent of fossils in florida. I was hoping to get some advice on finding good locations. I can remember going to endless spots that I feel like would be perfect now, with my father as a child. However he passed and unfortunately I have no idea how to find most of those spots again now. So I guess I'm starting at square one. This weekend Im renting a canoe and going down the little withlachoochee to search for some good hunting grounds. That river is close enough for a good day trip and I think the water is pretty low at the moment. If anyone has some advice on if the little withlachoochee is good or bad for finding sharks teeth or the best way of going about it, it would be greatly appreciated Happy to have found the fossil forum -John
