Jesuslover340 Posted October 18, 2020 Author Share Posted October 18, 2020 Well...I've learned a few interesting things myself, reading these responses! I had no clue about the whole Cretaceous Squalicorax from Maryland being interesting, for example. As said, I really don't know my shark material, so by all means if you want to ramble, ramble, haha! I'd love to learn more Still have another box to go through at some point...

By all means, please type away! As said, I know comparitively little on shark teeth, so don't much know what would stand out or not in terms of being interesting, besides rarity and location. I hope to learn a bit more on them during my break between semesters at university.

Jesuslover340 Posted November 2, 2020 Author Share Posted November 2, 2020 I'll get back to this thread when I have time. Uni just wrapped up for the year but now we've been kept up with an associated partial Diprotodon skeleton we've had to excavate and now look to prep. Anyways. Anyone know what the heck a Zamponiopteron is??? I have a fin of one here and I can't seem to find much on what it is in relation to other sharks or whatnot. To the naive eye it looks Cladoselache-ish to me but I've no clue, to be honest. @fossilsonwheels any idea? Seem to be knowledgeable.

siteseer Posted November 4, 2020 Share Posted November 4, 2020 On 10/12/2020 at 3:36 PM, WhodamanHD said: Yessir, we actually have relatively extensive late Cretaceous marine beds but most have been built over. Over the years, many have been cut into by construction and hunted intensely for short periods. A creek in Bowie with a productive lag layer was intensely hunted for a long time, sifted and dig out so bad the bank collapsed at the owner at the time (UMd) banned collecting. Though the owners have changed, no point in going there. The layer is gone and the bed is under feet of overburden. I know one guy who still finds stuff occasionally but he is the best I know in terms of search image. I went once, not a single fossil in sight. You still see the fossils extracted during the old days circulate though. There's a paper on the Bowie site: Hartstein, E., L. Decina, and R. Keil. 1999.

siteseer Posted November 4, 2020 Share Posted November 4, 2020 It's a great collection of teeth. Some teeth are from sites now gone or at least restricted by the landowner. The Bean Creek site and other Santa Cruz County sites for teeth from the Lower Santa Margarita Sandstone are similarly gone partly because they are overgrown but mostly because the landowner changed and the current one does not allow collecting. In one case a storage unit facility now sits on the site. I collected there back in the late 80's-90's. The best teeth I have from there I traded for from longtime local collectors. As a further note, the teeth you tend to find in those sites are usually just a crown or they have the root but the whole tooth is quite worn. Spme notes: The Orthacanthus fin spine looks more like a section of the head spine. That Squalus from Orp-le-Grand is a nice one. I don't see teeth coming from that site anymore. The few I have were traded for maybe 25-30 years ago. I wonder if the site is still producing. I haven't seen teeth from Eben-Emael, Belgium but someone told me that teeth were there so it was nice to see that Serratolamna. The site is better known for echinoids. That Otodus from the Middle Eocene of Romania might be an early Parotodus. That gill raker must have been collected before the 90's if the label says "Czechoslovakia." The Carcharinus priscus from Horse Creek, FL is a lemon shark tooth, Negaprion brevirostris. You have two teeth identified as Cretolamna appendiculata from Eufaula, AL but the one on the left is Scapanorhynchus. You can't collect at Lee-on-Solent, UK anymore so it's nice to have a sample from there. Myledaphis is spelled Myledaphus. I don't want to sound like a stickler on spelling. I have typos on this forum. It's just that if someone is looking for information on Myledaphus on this forum, it might not come up in a search if it is spelled different.

Great stuff, Jess Thank you for the great information! Many of the closed sites make sense in light that the majority of these teeth came from older collections or collections comprised of older collections. Most of these teeth were given in a superbly generous trade, offloaded as gifts, or offered at a friend's price through various trades or dealings with members over time. All of the better material comes from an older, more extensive collection that I'd equate to the shark tooth equivalent of Troodon's dinosaur tooth collection, haha. Would you know much more on Otodus vs Paratodus from Russia? Anyways-here's some more I will wade through: Megalodon tooth, Middle Miocene, Victoria, Australia: Zamponiopteron falciformis: Isurus hastalis, middle Miocene, Victoria, Australia: Carcharias taurus, Australia: Carcharhinus brachyurus, Australia: Heterodontus cainozoicus, Australia: Galeocerdo aduncus, Australia: Isurus oxyrhinchus, Australia: Orectolobus sp., Australia: Notorynchus primigenius, Australia: Isuris hastalis, Australia: Isurus planus, Australia: Paratodus benedini, Australia: 1 "Let us therefore follow after the things which make for peace, and things wherewith one may edify another."-Romans 14:19 Link to comment Share on other sites More sharing options...

All I can tell you about Zamponiopteron is that the original material was from South America and included fin elements plus cartilage. I believe it is Chondrichthyes but not definitively a shark. I could be wrong about that though. I did read a paper that was related to a discovery in South Africa where they had found a fossil and the fins were very similar. I personally do not have anything in my collection from that genus. Link to comment Share on other sites More sharing options...

Jesuslover340 Posted November 9, 2020 Author Share Posted November 9, 2020 Heterodontus cainozoicus, early Miocene, Tasmania, Australia: Lateral teeth- Anterior teeth (had to take a pic at an angle because the camera on my phone did not want to focus on these piddly things, sorry)- Posterior teeth- Annnnd that pretty well wraps up everything I have! I do have some Orthacanthus teeth from the Permian of Waurika, Oklahoma, but they are elsewhere in storage with my other Oklahoman material. To my knowledge, this is every shark tooth/shark-related/marine fish material I otherwise have. I'd have to say the Helicoprion piece is my favourite thus far, but it's hard to choose among the others like Stethacanthus and the oddball Zamponiopteron. Still...it was nice going through it all 1 "Let us therefore follow after the things which make for peace, and things wherewith one may edify another."-Romans 14:19 Link to comment Share on other sites More sharing options...
fossilsonwheels Posted November 9, 2020 Share Posted November 9, 2020 I see you got your Stethacanthus tooth from Oklahoma. Congrats! It’s nicer than mine for sure lol Oh yeah those final teeth are so cool. Heterodontus is a personal favorite of mine. I had a chance to get an Australian tooth about a year and a half back. I had to pass on it and haven’t seen another available. We use the taxonomic displays primarily out of necessity for the education presentations. With a collection like yours I’d be tempted to go by location maybe. You could show off an impressive diversity of interesting locations. I would go by continent and create a sort of fossil map of the world lol Link to comment Share on other sites More sharing options...

I would go by continent and create a sort of fossil map of the world lol I did, haha! I sourced the Russian one first, then the Oklahoman one came up, followed by the Xenacanthus teeth from Scitland and Helicoprion whorl piece. So all of those were quite recent acquisitions. Aussie material can be difficult due to export reasons. Not a difficult process in itself, but it can take time and many people don't care to wait or go through the proper legal system of exporting Aussie material. Why is Heterodontus a personal favorite? Ha! I probably could, just about. I prefer the idea of categories, such as how yours are organised, but I'd be missing a fair bit. And that would just entice me to try and complete categories, which I don't need with how little space we now have!

I honestly have no clue how we are going to display a partial Diprotodon skeleton Once you head to taxonomic collecting you are going down a rabbit hole lol They have been around a long time and a diverse group especially if you include shark relatives. It’s addicting. Personally though I love it so I’d say go for it. The Bullheads are just remarkable creatures. They have been around for a very long time and relatively unchanged. Small and odd looking compared to other sharks but perfectly adapted to their environment. They have one of the strongest bite forces per body size in the shark family. Plus they are just kind of cute. Fossil wise, cool teeth and not easy to find. Outside of UK and STH material I’ve had a hard time finding much. The Paleozoic stuff is fun to collect. Fascinating and weird creatures that left behind interesting fossils. Link to comment Share on other sites More sharing options...
