Would you believe this tooth is from one of the largest sharks that ever lived?

𝘖𝘵𝘰𝘥𝘶𝘴 𝘮𝘦𝘨𝘢𝘭𝘰𝘥𝘰𝘯 (previously classified as 𝘊𝘢𝘳𝘤𝘩𝘢𝘳𝘰𝘤𝘭𝘦𝘴 𝘮𝘦𝘨𝘢𝘭𝘰𝘥𝘰𝘯) could grow to more than 60 feet long, cementing its place as the largest predatory shark in Earth's history.

Fossilized shark’s teeth! So many!! :) (Miocene, Calvert formation, Maryland)
Three and a half Carcharocles Megalodon or Carcharocles subauriculatus megatooth shark’s teeth in front of a jar full of smaller teeth. Mostly from the Plum Point area of the Miocene fossil cliffs in Maryland.

This very likely has some important implications for reconstructing Carcharocles megalodon!

Sharks just proved the 2/3 scaling law. 🦈📏 Using 3D modelling of 54 species, we found sharks follow the expected surface area-to-volume relationship almost perfectly — validating a key physiological theory.

I found this fossilized shark tooth yesterday and thought it might pass for this week's #BlueSkyArtShow theme #Jagged. I'm calling it Mother Nature's ancient art. 😊
A dark grey shark tooth with serrations on either side and a slight bourlette sits on top of pink fingers. There is a slight shimmer on it. I believe it is a fossilized Carcharocles angustidens.

A fossilized shark tooth of an Otodus megalodon from New Caledonia. Teeth from this locale are dredged from the bottom of the Pacific Ocean and are often extremely worn. This tooth still retains some remnants of its serrations. #FossilFriday

Carcharocles angustidens 🦈 #fossil #fossilhunting
The shark tooth from Tabby's previous video in her palm on the ride home. It's very shiny. The root has dried to a very light beige, and the blade is a warm golden brown that darkens to taupe toward the tip.

A fossilized shark tooth of an Otodus sokolovi from the Samlat Formation in Dakhla, Morocco. This species is sometimes synonomized with Otodus auriculatus, and represents a transitional form between it and Otodus angustidens.

#toothtuesday The largest tooth that I ever collected of the Oligocene (28-30 myo) megatoothed shark, Carcharocles angustidens, from Charleston, SC. Found while kayaking a lowcountry river with @tetrameryx.bsky.social and our friend Ashby Gale. 🦖🧪🦑
A hand holding a large dark gray tooth with a black root over a mudflat - it is shaped like an isosceles triangle and is a bit longer than wide. The enamel is encrusted with bryozoans and a bunch of barnacles.

Oh! Hey! Right on the path! #fossil #fossilhunting
A fossil shark tooth in dirt. The tip of Tabby's boot is nearby for scale. A fossil from an extinct prehistoric shark. It's a blue-gray and tan tooth with serrated edges. Likely from Carcharocles angustidens.

Don't go into the ocean. Why? Because it's Shark Week, baby! We are starting off strong with of course the biggest prehistoric shark of them all, the Carcharocles (Otodus) megalodon. This is the largest example I have in my collection. It comes from off the shores of South Carolina.
