So - saw the newly resurrected Alopias Grandis thread, and looking through I found the Elasmo guide. Anyway - one of my threshers, that I had labeled A. latidens - doesn’t quite seem to fit latidens. So… is it latidens? Grandis? P. benedini? It’s got a much more curved crown, and a very slightly different root. It measures 18mm in slant height.@hemipristis @Al Dente So here it is on the bottom - my other threshers are on top and look quite different: And pics of just it:

Hello, this is my very first find of thresher shark tooth over here in southern Slovakia (Lučenec region). Age: early Miocene/Eggenburgian (Central Paratethys). I have made some pictures from different angles to make the identification easier. It looks like Alopias exigua tooth to me., but since this is my first thresher shark I have some doubts... Have compared it to the extant Alopias superciliosus too (looks very similar), but this species appeared later in Middle Miocene, so I have exluded this option... If it is the Alopias exigua, I can add the first thresher shark species to my collection. Thank you in advance for your help.

I have a few shark teeth that require second opinions on the IDs. All are East Coast of the US. First up, a Pungo River micro. 4mm or so. This is a familiar tooth form to me as I’ve seen this exact tooth in STH micros. I had put teeth of this exact form in with Cetorhinus teeth because it’s so common in STH micro mix. I could be wrong about the ID on the STH teeth plus Pungo River is different as I believe Cetorhinus teeth are quite rare in that fauna. Both STH and PR have Cetorhinus and Alopias teeth. I believe there is a close familial relationship between those genera so I figured best to get other opinions before labeling this a Basking Shark. I had a very, very small amount of Lee Creek micros to pick through, like half a sandwich bag. The odds of finding a Cetorhinus in that amount of matrix would be astronomical lol It’s probably why I doubt my ID. @siteseer @sharkdoctor @Al Dente @sixgill pete Anyway, here it is. Cetorhinus or Alopias or door #3 ?

Originally described from the Oligocene of Belgium (préliminaire sur des poissons nouveaux de l'Oligocène Belge, Leriche 1909) this tooth conforms well to the description. It is a rarely found tooth in Castle Hayne Deposits of North Carolina. Very similar to the Miocene A. vulpinas, I believe they cannot be the same with such a small sampling and a 25-million-year separation. Reference: Fossil Fish, Volume 3 of 4. North Carolina Fossil Club. Richard Chandler, 2015 pgs. 58, 59

The genus Alopias, commonly known as the Thresher Shark, has been around for millions of years. These sharks use their abnormally long, whip-like caudal fin to stun their prey. This fin can grow to become more than half the length of shark's entire body. It is a strange and fascinating creature, and has been one of my favorite sharks ever since I was a little boy. Today, we fossil hunters can find the fossilized teeth of Thresher Sharks. They are typically rather small, and relatively uncommon. They look really cool in my opinion, and they're among my favorite types of shark teeth that are on the smaller side. So for this thread, SHOW US YOUR THRESHERS! I'll start by posting a neat little ring I made with my best Threshers so far. I'm excited to see what you all have found. Like I said, most of these teeth are pretty small, but I do understand that there's a species of Giant Thresher that can apparently be found at Calvert Cliffs and elsewhere. I've seen a few pictures, but never found one. Let's see what you all got!

Hi all, I went out for a quick shark tooth hunt this evening in Charleston, SC and had some awesome luck! I found these two Alopias grandis teeth right next to each other! They measure at 1.575 inches and are much larger than the other ones I have found. I also found a small lower Great White with a fully in tact root for the first time which have been hard to come by in Charleston. Love the dark blue crown and light colored root on it. Of course my phone died after I took the in situ picture of the Great White so I couldn’t get any in situ pictures of the two Alopias grandis teeth.

Hey all, I had a fun haul today in Charleston, SC (full haul in the first couple pictures). I was wondering if anyone could ID the first two teeth (pictures 3, 4, 5, 6) and let me know if they are A. grandis or a lateral Isurus tooth. Also, could anyone ID the mako tooth (picture 7)? Is it C. hastalis, I. desori/oxyrinchus, or I. retroflexus/paucus? Thanks in advance!

Hey all, I found these three teeth on a shark tooth hunt last week and a shark tooth hunt today in Charleston, SC. Just wanted to make sure I have the ID correct on them. Is the first tooth Galeocerdo mayumbensis or is it Galeocerdo cuvier? Is the second tooth Alopias grandis? Is the third tooth Alopias grandis? Thanks in advance for the help.

OK, these shouldnt be too hard. I have hunches, but not really strong on these types. First is from Belgrade mine, NC. Thinking alopias... These three are from Lee Creek. Not at all sure... Fairly certain these guys are alopias...

Hey, I saw this tooth and I’m considering asking if they’ll trade it to me... first I want to know, is it a palatasi, if it is I’ll ask, but before I ask I want to know. It was found in SC and looks to be about an inch. TIA! @digit @Harry Pristis @MarcoSr

Hey all, I just found a great Alopias grandis tooth today In Charleston, SC that I thought I would share. I have found a couple partial ones, but never a full one with the root.

Hello Everyone, I’m rather fond of Giant Alopiids, and I have taken to collecting them. I find it strange that such a wonderful, yet mysterious creature remains relatively unknown and scantly studied. I may have space in my high school schedule for an independent study senior year, and I’ve considered using it to make a poster or paper on their morphology, taxonomy, phylogeny and such for The Rostrum or something. However, I’ve heard tell that there is already a comprehensive paper on giant alopiids in the works. We’ll see if there will be anything left for me to discuss. Anyway, collecting them is a slow process as they are quite rare and I am quite cheap (I have yet to find one myself). I thought I’d make a thread to show off what I have thus far and to keep them cataloged for myself. Hopefully this page will grow as time goes on Dashes are around 1 inch apart.

Hi, i have this thresher tooth that was found in the same area as some typical A. grandis teeth from South Carolina. I’m leaning towards grandis for this one based on size, bit it has a symmetrical shape that none of my other grandis teeth have. I am not familiar with grandis anterior teeth, perhaps it that? Thoughts and opinions appreciated. cheers!

This was apparently published in September 2018, but it slipped past me and I’m posting it here in case it slipped past my fellow thresher lovers. The allusive serrated giant thresher has been named Alopias palatasi. Of course if you like Trigonotodus better, it is Trigonotodus palatasi. Now when I add one to my collection in the far far future, I can finally put a good label to it!

1. Thought this was an oddly curved posterior Meg, but maybe Thresher Alopias?? Calvert Fm, Westmoreland St.Pk, Virginia. 2. Posterior Meg or Thresher?? Calvert Fm, Chesapeak Beach, MD; more worn than #1 above, but very similar. 3. Notorhinchus (Notidanus) upper or Echinorhincus blakei?? Calvert Fm, Chesapeake Beach, Maryland Any help making a positive id would be appreciated. Thanks in advance.

I have been trying to find out some info about the tooth I have. As far as I can tell it's an alopias grandis, and much bigger than others I have seen online. I'm mainly trying to find out what it may be worth and/or where I could sell it.
