Show us your Ginsu Shark Teeth!


HoppeHunting

Recommended Posts

I've recently become very interested in the sharks of the Cretaceous. The largest of all sharks during this time period was supposedly Cretoxyrhina mantelli, or the "Ginsu Shark". It likely would've highly resembled the modern Great White. I looked up a few images of their teeth, but I was wondering if anyone who hunts the Cretaceous here on the forum has any of their own? If so, I'd love to see them! Hoppe hunting!

I think they are cool to, strangely they rarely come up for sale I’ve noticed. Thus I do not have one, they are cool looking though.

Happy hunting,

Beautiful tooth.

My one and only. Whodaman is right; I've wound down my buying quite a bit lately, but when I was actively searching, they didn't come up for sale all that often.

Thanks Andy. I've added a couple since I took the pic. That's a nice one you have. My friend found one that makes that one look small. I may be able to talk him into selling if you are interested?

Makes mine look small? Now I am intrigued. Gimme the details man!

His is quite long maybe not as wide. I'll see if I can get some pics. He's more of an artifact guy.

Not as wide as yours but long. This is the largest one I've seen come from my hunting grounds. Artifact pic and hand for scale.

It was one of the largest.  Scapanorhynchus, Cretodus, and Paraisurus teeth can extend over 2 inches but a tooth that size is quite rare.  I think I have a Cretoxyrhina about the size of Northern's.

Hi Don,

 

Yeah, a tooth that big and that nice is super-rare.  I've seen what the average Niobrara tooth looks like - weather-beaten and half the size.  Fossilselachian was collecting not too long after that species went extinct.

Not very good photos, but here are a few I've collected.  A lot of people probably don't realize that the older ones are quite smaller than the ones in the Niobrara.  The ones I find in the Greenhorn limestone are not too big.  They don't get giant until the Niobrara.  (The Cretodus are just as big however in the Greenhorn)

Don't have any nice C. mantelli, although I have various C. vraconensis from Albian of Kanev, Ukraine.

Have a number of isolated teeth by here is a partial associated dentition from the Niobrara Chalk Fm of Kansas.  Collected in 2004 from Hells Bar Canyon.  Largest teeth are 1 3/4" to 2"
