hi guys, i was hoping you could help me with this i am quite unused to hybodonts so i would really appreciate help, so far i believe it is Planohybodus grossiconus due to the striations being very short and only at the base of the tooth, here is a paper that describes bathonian hybodonts where i got my info from bathonian hybodonts thanks

Amazing complete shark fossil with 150 teeth. Hybodont shark first described from isolated spines now complete. https://www.cnet.com/news/rare-nearly-complete-fossil-reveals-giant-among-jurassic-sharks/

Hi everyone. I found this little fossil recently while working through a sandy conglomerate matrix I brought back from this summer's hunt in Wyoming's Lance fm. I believe it's a dermal denticle from some variety of cartilaginous fish, my first guess would be the Hybodont shark Lonchidion, but the guitarfish Myledaphus is also incredibly common in these sediments, however I haven't seen any pictures of denticles belonging to the latter or close relatives. It's about 2 mm long and about 1.5 mm tall. I would love to hear some input. Thanks, Noel

Hi everyone, So I was going through some matrix I brought back yesterday and I was processing it even though there were still big lumps inside. Then I came across a tiny shark tooth and I thought, ‘oh, that’s nice’. Then I noticed another black bit at the top of the matrix and started digging it out while thinking ‘theropod, theropod, theropod’ . Then, with one wack of my hammer, the matrix fell off and this beauty was there. What I initially thought to be a tiny sharks tooth turned out to be part of a huge one, it’s really nice preserved and has good striations. I think I found th

Hello everyone I found these shark teeth a while ago in Dorset and I remember posting them on the forum after I’d just broken them into pieces . I’ve since, glued them together but am not sure of the species. They were found in the bathonian of the forest marble formation and the larger one measures 15mm while the smaller one measures 5mm. I’m really sorry for the bad photos but it’s the best I could get. I think the larger one is asteracanthus sp. but I’m totally in the dark with the smaller one. Does anyone know what species they are? thanks in advance

Hey all, I thought I would make a thread to show some of my shark teeth that I have collected from the Oxford Clay formation (mainly the Peterborough Member), feel free to comment if I have misidentified anything! Pre-Apologies, some of them are quite small.. Cheers, Jacob.

Hello! I originally thought this was a Hybodont shark tooth when I found it (size is perfect) but I just realized that no other Hybodont tooth is my collection is curved like this. Is this possibly from a different part of the mouth or did I completely mid-label this one.. As always, all help is greatly appreciated! @Carl

Hasle Beach - Bornholm, Denmark (Mid Jurassic fossils)
Sauroniops posted a topic in Fossil Hunting Trips
Hello there fossil forum! This post will actually contain some of my finds from 2 trips to the same location, namely the island of Bornholm in Denmark. I went there this summer, and made quite an interesting discovery, which I will get back to, and then went on yet another trip, which I got home from less than a week ago. I doubt many of you know about it, unless you're Danish or have an interest in the geology of Denmark, but most of Denmark was underwater for pretty much all of the Mesozoic era. That is, of course, with the exception of Bornholm, which is a geologist's/paleo- 19 replies

Micro Fossil Report- Our first foray into the world of micros
fossilsonwheels posted a topic in General Fossil Discussion
I thought it would be fun and possibly helpful to other collectors to discuss the results of my first foray into the world of micro fossil exploration. I had purchased some quantities of micro matrix from two different formations and they provided vastly different experiences for me as a collector. I got a vial of micro fossils from the Neva formation which is from Kansas and is Permian. This stuff really proved to be quite a challenge and was not ideal to start with. These are TINY fossils and I was not equipped to handle such small fossils. Identifying the shark material was chal- 9 replies

From the album: Lance fm. Microsite Finds
cf. Lonchidion selachus Late Cretaceous (Maastrichtian~ 66 mya) Lance formation Hybodonts were a group of sharks which lasted an incredibly long period of time, however many went extinct with the non-avian dinosaurs. Lonchidion is a freshwater variety which went extinct at the end of the Cretaceous. -
I'm sure this tooth is from the Hybodont Asteracanthus genus but unsure as to the species. The root is missing but would appear to be whole. I'm also not familiar with its shape. Its mid Jurassic and from the Bathonian stage. Any suggestions please @siteseer@Fossildude19

Hello TFF Members. I found this in one of my fossil hunting spots recently and got several opinions on it . Several people have said this is a hybodont tooth and more specifically Polyacrodus. Scale is 1 inch and some people have also said the object next to it is a hybodont spine. Your thoughts are much appreciated!Thanks
