Got a couple finds from my Lee Creek micro matrix that I could use some help IDing. I’m assuming the first one is some sort of ray or fish tooth. 1. 2.

Here is (hopefully) one last post to help me identify some items I found while searching through the micro matrix from a Gainesville creek that Ken @digit was nice enough take us to. Some other items have been covered in previous posts:; http://www.thefossilforum.com/index.php?/topic/119097-gainesville-shark-teeth-question/&tab=comments#comment-1305867 http://www.thefossilforum.com/index.php?/topic/114209-north-florida-fun/&tab=comments#comment-1264293 The matrix comes from a creek in Gainesville, Florida and most of the fossils are from the Miocene aged Hawthorn Formation although there is occasional younger material. The fossil fauna is dominated by shark and ray teeth but there are lots of other items including: bivalves, gastropods, crab claws, fish parts, etc. (i.e. marine). What I have below are several items that I am uncertain about and hopefully someone can confirm my suspicion or give me a better idea. Thanks in advance for all your help. Item #1 is what I assume is a fish scale. Is that correct and can it be ID'd any more specifically? Item #2 is are two very tiny beautiful ray tooth. They look different from most of the Dasyatis and Rhynchobatus that I found with a much wider root. That had me thinking Rhinobatus but I'm not really seeing the uvula that I should expect so I could be way off. Any thoughts? Item #3 are a group of fish vertebrae. The two bottom rows are two views of the same 6 vertebrae and I have no doubt they are fish. It is the one on the top that I am uncertain about as it has a totally different shape. But I'm not that familiar with all the different permutations of fish vertebrae, so it may just be a different one. It reminds me of a mammal atlas, but maybe fish atlas bones look like that too. Item #4 are some items that I really have no idea. They look like little sacs and some are broken so that one can see sediment on the interior. While there is variability, most of them have a distinctive teardrop shape. Item #5 I am guessing may be burrow casts, but I'm not sure. Do they look familiar to anyone? Item #6 also look like casts of something, I'm just not sure what. They are generally very straight sections of a smooth tube form. All of the mollusk remains I have found are internal casts so no shell material is generally preserved in this deposit. Item #7 are, I don't know. My Paleozoic brain wants to call them eroded horn corals but I obviously know that is not right. Don't have another option in mind. And lastly, item #8 are probably worm tubes, just looking to see if that is right. They also have a common shape of being U-shaped or looped. They are not attached to a shell or anything (except maybe some matrix) like I am used to seeing with worm tubes. So that is my collection of oddities. I'd appreciate any thoughts folk have. Thanks Mike

I was very fortunate to obtain some loose matrix and chunks of matrix that I need to break down. I really have only been working on the loose matrix so far. It has not m.uch but has been extremely productive with amazing teeth. This is the first time I have gone through matrix from this area and the colors are amazing. The matrix is absolutely loaded with so much great stuff. Most of the items I have found so far are firsts for me. Enjoy the pics! @JBMugu I have barely scratched the survive with the big chucks of matrix but these two verts came out of it. They cleaned up nice! My first whale vert 1.5 inches. .75 inch shark vert Cow Shark Angel Shark Dog Shark

Some of us will do anything to sit and sift for shark teeth, ray teeth and fossils. Temp was good today 1-20-2020 so I headed to Mulberry Phosphate Museum. Some of us are older and not in the best of health so we go where we can to enjoy the hunt! Its a great place to meet families with kids and talk about hunting and more. I had just mentioned to one of the Mothers how great it would be if the Phosphate Mine would bring some larger teeth and such and mix in with the small rocks, reason is the rocks and all through a crusher and are all small so many shark teeth are very small and others are broken as you see in my finds today. An older Gentleman walked up by the name of James and he had with him a bag or large and small shark teeth, come to find out, he use to work for the mines. He comes to the rock pile and hides some larger ones for the people to find. Today he gave me and 2 of the young boys some great ones! They are not in the picture. Something to think about, if anyone has places disabled people can go and hunt it would be a great add on to this site. So many of us still enjoy the hunt but are not able to do a lot of walking and bending. Just a thought. Blessings when you hunt! Deb

Dear fellow fossil hunters, Joseph @The Jersey Devil and I went fossil hunting at an NJ Cretaceous stream on December 22nd and 23rd. On the 22nd I surface hunted, expecting a good wash out due to the previous night's rain. I had secured a section of the stream before realizing that someone had gotten to most of the stream before I had. Instead of continuing forward, I went back and explored some of the sections downstream that I had skipped. These too had been scanned so I ran back to my sifter that I had left upstream and then began sifting. Some hours later I was sifting and saw Joseph. We hadn't expected to see each other but were glad we did. Together we did some sifting and surface hunting before leaving. The next day, I arrived fairly early, hoping that the water had receded enough to expose some gravel bars that I know usually produce well. They were not exposed and I decided to do some water hunting, where I squat down and look in the water for teeth or whatever else I can find. The water was freezing and I was punished each time I went to grab something that was not a fossil. I had said hello to a jogger I saw over the ridge and later my friend Tyler, who does not have an account yet, found me and told me the jogger had mentioned that there was someone else hunting. Hunting on December 23rd has become a tradition between us. For three years now we have both unexpectedly found each other hunting on this day. Tyler did not bring a sifter and, with Joseph soon to be on his way, I asked Joseph to bring a third sifter. When Joseph arrived we all went upstream and began hunting. Not that long into the hunt Joseph found an excellent mosasaur tooth that put me on overdrive trying to find something of equal or greater significance. This did not materialize, but I did end up finding a lot of fossils. Tyler found an awesome heteromorphic ammonite. Some time later Tyler and Joseph decided to do some surface collecting and Joseph found a killer point. Joseph lent Tyler the point for him to study and replicate; Tyler is an awesome upcoming flint knapper. Together we all had fun and I look forward to future hunts with them. Hopefully we all may be able to go hunting with Dave @Darktooth and Frank @frankh8147 this Friday.

Is there such a thing as pathological ray like there is shark teeth?
-
I'm Cody from Maryland me and my wife Cayla have been Shark tooth hunting at Flag Ponds Nature Park in Maryland for almost a year. We started out really slow. Had no idea what we were looking for but after the first few trips it gets easier and easier. Even though our favorite collection site is 2 hours from our house we try to make it there every weekend.

As rays in a number of species grow, they increase the number of teeth in their jaws through a process called file splitting. The below pictures and text are from elasmo.com: “In the accompanying image of the Roughtail Stingray, the fifth upper left file is in the process of splitting. The oldest tooth (at the labial margin) has a normal design. The following tooth is laterally expanded and by the third row, a second cusp is clearly visible. It is possible that these teeth still share a common root. In row five, there are now two teeth occupying the old (now expanded) file 5 position.” I’ve seen a number of examples of file splitting ray teeth in the fossil ray teeth that I collect and I thought that I would post a few examples. I just recently found an example of a file splitting tooth (3 mm) from an Archaeomanta melenhorsti ray from the Eocene of Virginia. In this specimen you can see two distinct crowns but the crowns haven’t fully separated yet (there is also a bit of pyrite between the crowns) and two root lobes but they haven’t completely separated yet either. Here is an example of a file splitting tooth (2.5 mm) from a Coupatezia woutersi ray from the Eocene of Virginia. In this specimen you can see two distinct crowns but the crowns haven’t fully separated yet and there is only a shared single set of root lobes. Here is an example of a file splitting tooth (4.5 mm) from a Dasyatis sp. ray from the Miocene of Florida. In this specimen you can see two completely separated crowns but the root lobes have not fully separated yet. If you have any examples of ray file splitting teeth in your collection, please take some pictures and add them to this post. Marco Sr.

So I’ve been to Bracklesham bay 3 times now and never found a shark tooth or a ray dental plate, this was after hours of searching through the shingle on the beach and across the sand when the tide is out. I’ve heard that conditions for teeth are best after/during scouring conditions but I don’t live close to the beach. Can I go by the the weather being stormy or rainy? Also I’ve heard the fossiliferous beds can be exposed sometimes when the tied is out, is this completely random or connected to ‘scouring conditions’? Any helpful advice relating to best times to go and how to find out when the beds are exposed is greatly appreciated. Also any tips for finding teeth or dental plates? Thanks

Last week I had a great time to hunt in the Netherlands/Belgium for shark teeth. I was mainly at a good site near Antwerp but those finds I will post in the next days. What i want to show you here are the teeth and other things, which I found on various beaches there. For example i was in Cadzand or in Vlissingen. Too bad the shark teeth dont really have a good quality but nonetheless I am happy with my finds But pictures say more than words... Zwarte Polder: There its very difficult to find shark teeth with a good quality and the beach is often full with tourists. The fossiliferous sand comes from the Westerscheide so from eroding layers underwater. The fossils come mainly from the Miocene, Pliocene until the Pleistocene. Here are some "shabby" finds: (shark and ray teeth) The shark teeth are also very small ... This tooth is with 1.2 cm one of the prettiest: A damaged Geleocerdo: Beside of the shark teeth i also found some fish vertebrates. The biggest one is 1.5 cm long:

So I didn't know where to post this, but figured fossil hunting trips would be a good spot since the kids were doing an indoor fossil hunt! Today I did my annual class for the Western Interior Paleontological Society (WIPS) Kids Club. It is always a hit, but due to scheduling I was unable to make the February class and did this one in May. May tends to be a smaller group because of the nice weather and vacations, but we still had a great time! The adults even wanted to get in on this activity and I was more than happy to help! The worst thing that happened was I forgot to take lots of pictures! I took (2) 5 gallon buckets of matrix, one bucket from Peace River, FL and the second bucket from Aurora, NC. I talked to the kids about how fossils in different locations can be similar (ie. shark teeth!) and we explained the importance of labeling your finds! Each person was given (1) 5-ounce cup of matrix from Peace River, and (1) 5-ounce cup of matrix from Aurora. We set up microscopes and laptops an allowed the kids to photograph their 5 favourite finds. We set out books, posters, and print outs to help with the identification part. They then loaded these photos on to a USB and have some very nice detailed photos to take home with all of their finds. That's right, I let them keep EVERYTHING! One kid found a cookie cutter tooth, full root and all! I don't even have one in my collection yet! Aside from keeping everything they found I made sure to send each kid home with a small 125mL bag of each matrix, and 5 various fossils from my Peace River hunting trips ((3) 25mm+ shark teeth, a dugong rib, and a turtle piece.) I shared with them my preferred methods of hunting and encouraged them to try their own! All in all it was a great day with lots of very nice finds! Thanks again to @Sacha for sending me Peace River matrix for my classes!

Hello everyone, I went fossiling today, April 14th. I got to Ramanessin Brook around 9:00 AM and ended at about 2:45 PM. The day began slowly, with me haphazardly choosing places to sift. From all the boot prints on the ground it was apparent that many people had gone surface scanning a few days before. I did find one or two teeth on the surface in the middle of the gravel bar, they must have missed them. While I was hunting there was a caravan of senior citizens hiking on one of the trails. They thought I was panning for gold but when I showed them the finds they were stunned. Some of them had never seen sharks' teeth before which seemed odd. One woman with a very heavy German accent was particularly interested and I was happy to give her some of my finds. After that interaction I went back to hunting. With the finds beginning to dwindle in the area I was searching, I moved on. Not much was had further upstream unfortunately. A few minutes later I cut my finger on a stray wire from my breaking sifter and then hiked back to my dad, who was sleeping in his hammock, about a mile or so away. The day was pretty good, my best finds being a Xiphactinus sp. and Ratfish jaw section. Bone, Vertebrae, and one (or two) Xiphactinus Teeth Ghost Shrimp Parts, Sawfish Rostral Spines, Small Vert, Pychodont tooth, and Unidentified Mammal Tooth Ray Teeth

Hello everyone, Trevor here. Today I went with my father to Ramanessin Brook in New Jersey. Yesterday there had been light but extended rainstorms and was hoping that the storms could expose so new formation or clean up some gravel bars. Much to my dismay the stream was almost completely flooded, with many portions of stream just slightly below my torso. All but one of the gravel bars were exposed in the first stretch of stream I explored. I did some sifting which was not very productive. I decided to try further upstream and found that there were a few more gravel bars. Along the way I met a funny group of students geologists from Stockton University near Atlantic City (if I remember correctly) practicing their hand at fossiling. If someone goes on Monday or even tomorrow they may find double what I came across. The streams need a little bit of time to subside and then many finds will be exposed. I found some odd bones and was wondering if someone could identify them. The first I believe is a vert and the second I have no clue. My questions: Are they fossilized? Are they pleistocene if fossilized? First Unidentified Bone:

Hello once again! Well, March Break has finally begun, so my daughter Viola and I decided to spend some time sorting through the Sharktooth Hill micromatrix that Ken (@digit) sent me as part of the "rolling auction" lot that I won last month. Here are some pictures of a few of the finds so far... Ray teeth? - different from the usual plates that I've seen before Cow shark (Notorynchus sp.)? Dogshark (Squalus sp.)? Marine mammal teeth? Any ideas? Cute little shark teeth in matrix - any ideas re: their identity? ??? ??? I'll post pictures of more items on another day, when my eyes have stopped burning Thanks in advance for your help! Monica

The second part of my trip finds ... http://www.thefossilforum.com/index.php?/topic/68391-teeth-and-more-from-antwerp I was three times on a beach near Vlissingen, named "de kaloot" in the Netherlands. Its a very good location for collectors because its not that used for tourism. You can only collect there at low tide. I found some shark teeth, ray teeth, some bones and some bivalves. The shark teeth are normally very small and not that nice ... Here is my whole haul: The best tooth is this 2.8 cm long shark tooth (Please help to id this find): Another smaller tooth with a lenght of 1 cm is this one: I am not sure with the ID ... If you want i can take more detailed picture of the shark teeth ... I also found some bivalves like this three Glycymeris: A rare find was this Pectenid: (5 cm long) In contrast to the location in Antwerp i only found one bone: (13 cm long) Last but not least ... another good find: A big fish vertebra with a size of 4.5 cm ! Thanks for viewing ! Hope you enjoy

The last two weeks i was on vacation in the Netherlands. I was there with my whole family so i couldnt search that much ... The best location was near Antwerp (Belgium). There was desposited sand from the Westerschelde (with fossils). Unfortunately, the times in abundance are over and its very overgrown now, but at a few places you can still find something .... Looks good .... The best method is to dig a bit and sieve the material. Now my finds ... I found many shark teeth, bones and other cool things. Most of the shark teeth are very small and often they are damaged or unrolled. In two times i was there i found some good teeth with a length between 2-5 cm. Here you can see some: (sry on the top right corner are teeth from Vlissingen) I tried to determine some of them so please correct me Detailed pictures: A nice 3.6 cm long teeth ... think it could be Isurus oxyrinchus. Cosmopolitodus ? The tooth is 2.3 cm long. This tooth was very common, but i dont know the name ... (Length: between 1 until 2 cm) Carcharias acutissimus (1.6 cm long) Carcharoides catticus (1.8 cm long) And the last shark tooth i want to show (for now) is this very small (0.5 cm long) Notorhynchus sp. :
