HoppeHunting Posted March 22, 2018 Share Posted March 22, 2018 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!

Miocene_Mason Posted March 22, 2018 Share Posted March 22, 2018 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. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

Northern Sharks Posted March 22, 2018 Share Posted March 22, 2018 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. 3 There's no limit to what you can accomplish when you're supposed to be doing something else Link to comment Share on other sites More sharing options...

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? 1 Link to comment Share on other sites More sharing options...

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.

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.

Ramo Posted March 23, 2018 Share Posted March 23, 2018 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) 8 For one species to mourn the death of another is a new thing under the sun. -Aldo Leopold Link to comment Share on other sites More sharing options...
Anomotodon Posted March 23, 2018 Share Posted March 23, 2018 Don't have any nice C. mantelli, although I have various C. vraconensis from Albian of Kanev, Ukraine. * C in the last two pics are most likely Dwardius (upper lateral and symphyseal) 5 The Tooth Fairy Link to comment Share on other sites More sharing options...
