From the album: Sharks
Just a handful of Cretaceous species, most from North Texas. The sea that bisected North America ~85 million years ago played host to a diverse and burgeoning ecosystem that supported many species of sharks. It was likely due to specialization that allowed these sharks to all live in the same place and time. -

Reconstructed tooth set from a "Crow" shark - Squalicorax (could be S. falcatus) - illustrating the variety of tooth positions. Anterior teeth have erect, triangular cusps. Lateral teeth and posteriors are more common and have an increasingly posteriorly slanted crown, resembling the teeth of modern tiger sharks. -
Recently I purchased these two Squalicorax sp. tooths from an auction website and both are currently on the way. I have a few questions about identification since I know very little about shark tooths and also please correct any misidentifications. Seller A sold me this tooth and it was listed as Squalicorax hartwelli. It is collected from Niobrara formation in western Kansas. Is Squalicorax hartwelli considered a variation of Squalicorax falcatus? Do you agree with seller A's identification above? Seller B sold me this tooth and it was li

Nothing extraordinary, but I found an area with several chunks of matrix with teeth in them. -

Over the Columbus Day weekend, I planned to make a trip up from Virginia to New Jersey to visit my mother and other family. The trip offered the opportunity to check out one of the cretaceous sites in NJ that I have read about so much here--and that my son has been begging to visit for, like, a year. Never having collected there, I reached out to forum members @Trevor and @The Jersey Devil for any suggestions they could offer to a couple of cretaceous creek newbies and they really came through! (Thanks, again guys!) With tips in hand we arrived at our collecting location early on Sunday, ho

Didn't find much this time. I don't think it's rained in a while - the water looked stagnant. Also was picked over well. Favorite find is the mostly complete Cretodus (found it under a fallen tree).-

I ordered 3 Mosasaurus teeth, 1 Crow shark tooth and 1 Enchodus tooth. Do they seem real? And do they have any signs of restoration?

Our Shark Education Program- Cows, Crows, and Goblins
fossilsonwheels posted a topic in Member Collections
After the Hybodontids, our program starts to transition toward the modern sharks. We introduce lamniform sharks and the cow sharks. We will not be able to spend much time at all on the Cow and Crow Sharks. They only get a brief introduction and a look at the teeth. Squalicorax is an important species for us even though we do not spend a lot of time on it. The students in first few classes we do presentations for will be going home with Squalicorax teeth from Morocco. We would like to spend more time on the Cow sharks eventually but we only have one tooth to show them and we will have to edit c -
Cretoxyrhina and Squalicorax (Ginsu and Crony) drawing
Macrophyseter posted a topic in Paleo Re-creations
After stuffing my face into tons of scientific articles on Late Cretaceous Lamniformes, I decided that I'd want to draw some sharks. Here's a drawing of the two infamous sharks of the Niobrara Formation Cretoxyrhina mantelli and Squalicorax falcatus as partners-in-crime. I've made the Cretoxyrhina ≈6-7 meters and the Squalicorax ≈2 meters. As 2 meters would be the same size as a very tall 6'6" human, you could imagine the Squalicorax as the tallest ordinary human and see how much bigger Cretoxyrhina is. I've always felt like Squalicorax would commonly accompany predators like Cretox- 12 replies

So we finally made it out to GMR to do some hunting. We left Greensboro about 7 am and arrived around 9:15. We walked around for a little bit to scout some areas, and finally found a good starting point. It was slow at first, but we started making really good progress when I found a 2" goblin shark tooth. We continued on throughout most of the day finding tooth, after tooth, after tooth... We found several Meg fragments, some super nice great whites, mako's, 3 mosasaur teeth (the smaller round one might possibly be a crocodile but were not 100% sure), and quite a few belimnites. After we finis

A nice example of a Campanian aged S. pristodontus. Though not as large or as nicely preserved as many of the Maastrichtian examples, a nice tooth.

Finally made it up to GMR last week. Was greeted by this as soon as I entered the stream/ditch. Once I got around this mess it was not too bad. Hunted pretty hard with not much to show for it. For me my favorite finds were the crow shark teeth, nice tiger shark and a dolphin tooth.

My first 2 pieces arrived today and I could not be more pleased! The Crow Shark tooth was a free little surprise with my Megalodon.
