Recently I aquired this Carcharodon tooth from Sacaco, Peru whose serrate conditions seems a bit peculiar to me. I can't really decide whether or not this tooth is from a late-stage hubbelli or an early carcharias. The serrations seem to wear/taper off just short of the tip on one side and abruptly end near it on another, and some (although not all) of the serrations appears to be angled in a way, although I suspect some may be due to wear. My thoughts on the serrations keep seesawing in my head. Would this tooth better represent a late-stage hubbelli or a carcharias? Thanks for any and all answers. Lingual

Day of the Sandtigers: Second Symphyseal? 1/5/19
FossilsAnonymous posted a topic in Fossil Hunting Trips
Hello all, I hope you are having a fossiliferous New Year. To kick ours off, MomAnonymous and I went off to Brownies to check out the beach. It seems I really do need waders as I was unable to round the point even at low tide. We met @sharkdoctor on the point who had found an amazing bird bone in zone 10. We chatted for a bit, and he gave me a lot of information that could prove very helpful, and even invited me to a group hunt at Blue Banks. What a generous man. I get good luck when meeting other collectors! We putted around for a bit, finding some really nice sand tigers at one point and a lot of other, small teeth. Then we went to the bridge, where MomAnonymous found another symphyseal Physogaleus in the exact same spot as before! In all we got 137 small teeth. Not the best of days, but not horrible either. @Littlefoot @racerzeke @ShoreThing @WhodamanHD -

I’m eager for some help identifying this shark tooth fragment I found while beach combing on Hilton Head, SC. I’ve found many, many sand tiger shark teeth here over the years, but this is by far the largest. It’s only a fragment, but the size with the huge nodule on the root is so very different from what I usually find on the beach. Is this indeed from a type of sand tiger shark? I’d love to learn more about it.

Hello guys and gals, I greatly appreciate this forum and thanks for welcoming me. I have a set of 4 teeth that I only know that are from Florida. I’m thinking Carcharias but I’m a noob so I’m not confident. As far as the crinoids, I got them as a “gift” after purchasing a tooth from a dealer. All he knew is they were crinoids from Dakhla, Morocco. I’m guessing Pennsylvanian? Any information would be awesome. Thanks guys/gals

I'm not sure about the classification. This is the tooth in question: Shark tooth from Fiume Mareccchia, Italy I think it's a Prionace cf. glauca, @michele 1937thinks it's a Carcharias acutissima. Who can help? Carcharias acutissima with side cusps Prionace glauca without side cusps I don't think the tooth in question has side cusps, but I am not 100% sure. According to fossilworks, Carcharias acutissima is known from 43.0 to 5.332 Ma. Prionace is known from 5.332 to 0.012 Ma. Fiume Marecchia is Upper Pliocene, Zanclean to Piacenzian (younger than 3.15 Ma and Prionace glauca is mentioned in Sorbini's paper "BIOGEOGRAPHY AND CLIMATOLOGY OF PLIOCENE AND MESSINIAN FOSSIL FISH OF EASTERN-CENTRAL ITALY: That's mainly the reason why I decided for Prionace. Any thoughts? Thanks Thomas

Since my new dust sucking unit still hasn't been delivered, I've been twiddling my thumbs and wondering half the time what to do with myself, so I decided to hop on my bike this afternoon and take a little tour. For some strange reason (), I ended up on the forest track where you can scratch around in the miocene sandy gravel a bit and since by chance I had my trusty swiss army knife in my pocket, I decided to do just that. I found a few little bits, including a tiny drumfish tooth, but this was the best of the bunch. A Carcharias tooth with a length of 18mm. and a complete root.

Some teeth I found from Brownies that don't look like any other sand tigers I usually find. Many of them are very worn and broken. I'm no expert but my guess is that they are Eocene teeth. Any help is appreciated, thanks. Some of the larger ones

A very uncommon species at Lee Creek. From the Pleistocene James City Formation, great whites are always nice to find.

I mentioned in an earlier topic that I'd discovered a little site in the Miocene Burgidalian where you can scratch small Carcharias teeth out of a sandy cemented gravel-like conglomerate. I was back there again today and found these: The largest one without the root is 15mm. long. There were however 3 objects amongst them which I don't really recognize, although I'm thinking that the last 2 may be drum fish teeth. Anyway, I'm hoping that one of you fish experts here in the Forum might recognize them and can point me in the right direction. I'm not even sure if this first one, of which I've made 5 photos, top, bottom and 3 different side views, is even from a fish. It measures 11x6x4mm. The next one is 5mm. long. And finally the 3rd one has a diameter of just 2mm. All of the photos were taken under the microscope. Thanks in advance for your help and advice.

I've been visiting a little site in the Miocene Burgidalian on and off where you can scratch shark teeth out of the fine sandy conglomerate of the upper marine molasse. They are all tiny, but cute, ranging in size from 6-15mm. They were deposited in a narrow arm of the Tethys ocean at the time when the sea was retreating for the last time out of southern Germany and Switzerland, being forced out by the steadily northward moving African plate which was causing the Alps to raise themeselves up into the heights. I guess it was a spawning ground for little sharks, the larger ones spending most of their time in the open sea to the south. Anyway, I don't know all that much about shark teeth, but I've been studying the various types of Carcharias teeth, which apparently make up the majority of teeth found in these layers. I'm just wondering if they all belong to this genus, or if maybe some other ones are there amongst them, or if at least different species are represented. For this reason, I'm posting some of them here in the hopes that someone in the know can have a look at them and tell me more about them. Perhaps in which part of the jaw they are lodged, or even if the one or the other tooth belongs to a different genus. I'll number the photos for better orientation. Thanks in advance for your help. 1 2 3 4 5 6 7 I was also wondering if the following object is a shell-crusher tooth or if it's just a tiny, shiny pebble. It has a length of 6mm.
