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! Here is the description: https://www.researchgate.net/publication/327871783_Kent_Ward_2018_Alopias_palatasi

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!

Hello everyone, since school has let go I've had an opportunity to get back in the water and do some quiet and relaxing hunting. The leaves are falling in the bucket fulls so that does tend to clog things up a bit at this time of year, but the weather has been warmer than usual and the spouse gods have been in my favor. I've had a time documenting some of the more interesting finds. I usually give the haul a good single flatbed scan to archive everything by date and then concentrate on anything interesting. Some color about, which means they haven't been sitting on the creek-bed for too long. A 'dolphin' tooth that isn't completely eaten up .. etc ... I have to say my sailing boots though have made up from their disuse since my time in California (*sigh*). It seems that the extra rubber and neoprene work well in the muck and mud, and keep my digits safe from the broken glass. They are warm on my feet too which is usually the first thing to go .... The Angustidens are always my favorite .. Most are in pieces but when you pick up one with some color or a good tip the curses about the missing cusp fade away. Small teeth with big color .. Billfish hypural from the Chandler bridge and the Ashley fm. Marl (in matrix) . I find rostrum fragments occasionally. Fish jaw part The best and least common are the teeth locked in the matrix. Most likely Ashley fm. below the Chandler bridge. The Aliopias sp. in this location are always small. Maybe the water at this spot wasn't deep enough back in the day .. Vert and tooth ... this tooth is probably my best from the creek. They can take a beating. Cheers, Brett

Hello folks, Long time no see .... Wanted to share a few finds from the creek-bed. My first two toothed whale teeth popped up in a recent trip, worn but fun. There were a few angustidens as well, and an alopias sp. that was larger and a bit broader than I had seen before. The best part honestly was almost lost ... it's those moments when you pause as you are tossing chunks of larger rock back into the water. Not one, but two little teeth still locked in their matrix came up in my sifter. Cheers, Brett

Hi There, I'm curious about this small tooth that popped up in my sifter from a creek bed in Summerville, SC. I've looked at references for Mako shark species (elasmo) to try and figure it out (retroflexus ?). It isn't the usual shape I'm used to, the root is not as robust as I'm accustomed to and the tooth in proportion to the root feels too squat. Does it just have an odd pathology or abnomality ? Or is just not an Isurus sp. at all. Thanks, Brett

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.
