Finally ... a discussion of fossil sharks from Morocco and transitional teeth.
Northern Sharks posted a topic in Member Collections
Santa came early here in the north country. I've been after one of these for a while and I finally got one in the mail today. It's an early, transitional form, Palaeocarcharodon orientalis. Very coarse serrations near the root fading to almost smooth at the tip. One root tip was glued back on as these teeth are very prone to damage, but I can ignore that because it's almost 2 inches long, and they don't get much bigger than that.

I'm finally getting around to posting pictures of this Moroccan shark tooth, which I believe is either a transitional Otodus obliquus or a transitional Palaeocarcharodon orientalis. My original thought was Otodus but @Al Dente flagged in the mailbox thread a few weeks ago that it might be Palaeocarcharodon instead. Any thoughts on this one? The tooth measures 49 mm on the slant and is 39 mm wide across the root.

I got to Purse a couple hours before low tide and got a good 5 and a half hours of searching. Managed to scrounge together over 1,000 teeth, most of them pretty small, a new personal best. I didn't find anything of significant size, but a handful of oddities/rarities. One such oddity was what looks like a Carcharhinus (Gray/Dusky Shark) of some sort. Perhaps some folks came to Purse following a hunt at Westmoreland or some other place and a tooth slipped out of their bag. This is a first for me. I found a worn down palaeocarcharodon with some nice dark blue coloration, some crocodile teeth, among other things. I found a neat little fossil of some sort that I can't identify, it's about 0.8 mm in diameter. Images: https://imgur.com/gallery/d0qdUxU

I got this tooth mixed in with a bunch of small Moroccan stuff and it struck me as something a little different. To me it bears a striking resemblance to Palaeocarcharodon, without the serrated blade. It doesn’t look right for Otodus or Cretalamna to me, it’s too delicate and thin, very much like Palaeocarcharodon. Any thoughts or suggestions on it identity would be appreciated. Happy newyear!

Possible ancestor of great whites and megalodon.
