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

Had a quick hunt this morning at Matoaka. It got crowded quickly. Water was clear. All beaches are crowded now. Nice variety of teeth.

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.

This is an eagle ray toothplate from the Suwannee River. Most often, these toothplates are disarticulated into single teeth. Note the wear on the occlusal surface, probably from crushing hard-shelled food items. Family MYLIOBATIDAE Subfamily MYLIOBATINAE Myliobatis sp. Late Oligocene Suwannee Limestone Suwannee County, Florida (This image is best viewed by clicking on the button on the upper right of this page => "other sizes" => "large".)© Harry Pristis 2015
