    A Classic Hunt on the NSR

    I think North Texans will relate when I say that now and then, the urge to take a drive out to the NSR and spend the day hunting some Campanian gravel bars can spontaneously take complete hold. I had one of those moments just after the series of heavy rains and powerful winds our region encountered some days ago. Previously, my luck with weather at the NSR had been rather poor. Each time, the temps were either nearing a hundred degrees or only just above freezing, making a full on adventure crossing muddy waters and crawling atop unshaded gravel beds too much to handle. I had yet to experience

    Big brook mystery fossils ID help

    Hi all, it's me again! for my first expedition of the year, I decided to go to big brook to try my hand collecting there. had quite the adventure, found some neat things. but there are a handful of oddity's that I am unsure. in my research that ive done over the day I have a couple ideas, but any confirmation from experts is always appreciated. first one up is this weird thing. I'm not sure what this is although it's no concretion these ones are also strange, but I have some ideas on a few of them. top two are probably vertebrae fragments, but I have

    Hybodont shark tooth? - Aguja Formation

    This tooth was found in micro matrix from the Aguja Formation. Thinking possible partial hybodont tooth. Your input is appreciated. Buccal view and size Lingual view Lateral view (to show curvature, I know the picture is snarge) Magnified buccal view, to show detail. Thanks in advance!

    Aguja fm. Micro Shark Teeth

    Hi everyone, tonight I wanted to share some pictures I took of the tiny chondrichthyan teeth I found in the Aguja matrix I got last year. I was hoping someone may be able to shed some light on their identity as there appears to be a few different types represented. 4 mm 3 mm 3 mm 5 mm

    bathonian watton cliff hybodont

    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

    Dermal Denticle? Lance fm. Wyoming

    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

    A nice surprise

    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

    Hybodontid shark teeth

    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

    Hybodus sp. Shark Teeth

    From the album: Post Oak Creek

    Small hybodont shark teeth from the Late Cretaceous of Texas.
  12. 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.

    Hybodont?? New Jersey Cretaceous

    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
  14. 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
  15. 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

    Hybodont Spine

    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.

    Possible Hybodont tooth

    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

    Hybodont cephalic clasper

    From the album: Sharks from other locations

    Hybodont Shark

    A great example of this uncommon tooth. These are very rarely found with a root.

    Possible Hybodont Tooth From Texas

    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
