fossilsonwheels Posted March 1, 2021 Author Share Posted March 1, 2021 Pachyscyllium distans Miocene Hobmamisbach, Austria A couple of notes. I believe Pachyscllium is the right genus though I’ve seen these also called Scyliorhinus and even Premontreia. This tooth was a gift from our friend @siteseer. It is also our only tooth from Austria which is cool because I have a bit of Austrian heritage in my family. 1 1 Link to comment Share on other sites More sharing options...

fossilsonwheels Posted March 6, 2021 Author Share Posted March 6, 2021 Here’s a new addition and this comes from micro matrix provided by @sharkdoctor. Aaron has posted some from Old Church already but I’m pretty happy I found one so here you go. 1 Link to comment Share on other sites More sharing options...
fossilsonwheels Posted March 6, 2021 Author Share Posted March 6, 2021 Some beautiful little teeth to share from the Calvert Formation. @sharkdoctor included three of these in the package he sent and we’ve found three so far. I’d call these Scyliorhinus but no idea on a species. They are pretty tiny, between 1-3mm. 1 Link to comment Share on other sites More sharing options...
sharkdoctor Posted March 8, 2021 Share Posted March 8, 2021 I'm so happy you are having fun and finding catsharks! Brett Kent just calls them Scyliorhinid sp. and declines to speculate further. in his words, "Given the currently unsettled state of Scyliorhinid systematics and the high morphological overlap of teeth in this group, the specimens from the Calvert Cliffs are assigned only to familial status." 2 Link to comment Share on other sites More sharing options...

I can completely understand that. I have found 3 plus the 3 you sent and in just those 6 teeth there is considerable variation in morphology. I would imagine changes to fossil Catshark taxonomy probably occurring across a wide temporal range in the future given the extant diversity. That is really helpful information. Ive toyed with the idea of going back to school for Paleontology. I’m really interested in the fossil records of deep sea sharks and would love to study them. I am fascinated by Squaliformes, Goblins, Catsharks and Hexanchiformes. My kids are telling me to do it lol 3 Link to comment Share on other sites More sharing options...

fossilsonwheels Posted January 23, 2022 Author Share Posted January 23, 2022 Not exactly Catshark teeth. More like the whole Catshark.... probably. I believe this is a Catshark and not an Orectolobiformes but am not 100%. I’ve had different opinions given to me but I lean Scyliorhinus so I decided to put this in the thread. I can say I LOVE my shark. It’s really quite cool to have a fossilized shark. We’ve discussed adopting another one.

fossilsonwheels Posted June 25, 2022 Author Share Posted June 25, 2022 (edited) Scyliorhinus teeth from STH are pretty hard to come by so I’m really excited to be adding this tooth to my collection. Thanks to @will stevenson, I can cross this one off my list. I should add that this tooth has similarities to the teeth of Cephaloscyllium. I was checking out J-elasmo and I think it’s possible this is a Swell Shark tooth.
