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.

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
Hello everyone, I bought this tooth a while back from @Sharks of SC and it’s been nagging at my brain for a while. SOSC came to the conclusion it is a thresher tooth (and I do agree) but it has two cusps. As far as I know, Trigonotodus alteri is the cusped variety of giant thresher, but usually only has one cusp each side. I seem to remember seeing another double cupped thresher for sale a long time ago, but one of the cusps was very reduced. Information on these guys is incredibly scarce, so I was wondering what your (the clever people who inhabit this forum) thoughts were on it. It’s from the chandler bridge fm (oligocene) in SC, although Miocene fossils sometimes find their way in. According to SOSC other thresher teeth were found at the site. I considered the possibility of serratolamna, but none looked quite right and the age makes it very unlikely (though I suppose a thresher based on overall rarity is unlikely). SOSC’s pictures, I’m horrid at photography. About an inch slant height Thanks for any help! These threshers sure are interesting, I think I might have to start a thresher sub-collection...
