  1. I’m posting a few pictures from the trip I took with my sons in September 2016 to our Eocene/Oligocene Nebraska ranch. There are a couple of really neat areas on the ranch itself of which pictures are shown below. This is one small area of Eocene Chadron Formation on the ranch. The vast majority of the ranch is Oligocene Brule Formation. It is difficult to see clearly in these pictures but this area of the ranch has many visible different layers of the Brule Formation. The layers really stand out when the formation is wet and the colors are much more vibrant. These are two different dens in another part of the ranch. One had large footprints with five toes and claws all round it, probably from a bear. The other had large footprints with four toes and no claws all around it, probably from a mountain lion. I really wanted to get closer and get pictures inside the den but didn’t think that would be wise with the fresh footprints all around. We took out a good number of jacketed mammals and tortoises/turtles. However, none have been prepped yet. We still have over twenty specimens to prep from our May 2016 trip. I spent a couple of days collecting anthill matrix for the micro terrestrial vertebrate specimens that it contains. Below are a couple of the anthills I collected from with a garden trowel for size reference. I wound up with around 8 ½ gallons of processed matrix from 8 areas in the ranch. Below are group pictures of the nicer specimens that I found so far in the matrix. I still have 1 ½ gallons of matrix to search. The fossil hackberry seeds and rodent incisors really stand out in the group pictures but there are a myriad of other specimen types if you really look closely. I also have thousands of bone fragments that I picked to send to Dr. Krister Smith who will search them for squamate skull fragments. You need quite a bit of experience and expertise to recognize these skull fragments which I can’t recognize currently. Continued in next reply Marco Sr.
  2. Here is a series of five images showcasing some of my finds from the first hunt through the Merritt Island matrix. I have just begun to study the fossils in this intriguing matrix, and hope that I haven't got too many wrong. There are so many possibilities when you find a bone in this stuff. It might be mammal, or reptile...amphibian, or even fish. The variety is one thing I wanted to showcase. Of course, the amphibian fossils are the really exciting finds, but they are the most difficult to identify. These images will be featured on episode 5 of 'Fossil Hunters'. continued in next reply
  3. A few weeks ago I submitted a request for ID on a couple of tiny bones from TFF member Sacha's Merritt Island Pleistocene matrix. http:// Small Pleistocene bone for ID - Fossil ID - The Fossil Forum The help that I received was based on the limited photos that I supplied. Lateral views alone just don't cut it! I was not satisfied with 'mouse', so I 'dug' a little deeper. I decided to re-photograph a few of the odd little bones in different aspects this time. Duh... my results really do illustrate the importance of showing the 'ends' of a bone. It was very obvious from my new photos that these are vertebrae. Then came hours of research and many PDF downloads. Turns out that these cool little bones are autotomous lizard caudal vertebrae. There seem to be at least two kinds in the matrix possibly representing different species (or positions in the tail). I have included some of the links to helpful papers on the subject. http://‎www.scielo.br/pdf/aabc/v87n1/0001-3765-aabc-201520130298.pdf http://The Anatomy and Histology of Caudal Autotomy and Regeneration in Lizards (PDF Download Available) http://Lizard Caudal Vertebrae on JSTOR
  4. I am currently cataloging the thousands of photos that I have accumulated of my finds from the Merritt Island, Florida Pleistocene matrix. Here are three that have me puzzled. The first looks like an ostracod... ? I was hoping that this tooth half was from something more interesting than a dolphin... It looks as though it has feeding damage...any ideas? And finally, this bit of jointed bone really has me stumped. Any guesses? Thanks for looking
  5. I have found the perfect way to answer the questions I get when trying to describe my passion for micro fossils! While out shopping yesterday, we hit a few favorite hobby/craft stores like A C Moore and Michael's. I found this neat little pocket watch designed to showcase tiny finds and bought a chain to match. Now I can keep it in the watch pocket on my jeans and easily show off a selection of micro fossils from Merritt Island matrix.
  6. Pleistocene ray, fish, salamander, frog, snake, lizard and mammal specimens from matrix from the Melbourne Bone Bed from the Indian River, Florida. I want to thank John Sacha for supplying the matrix. This matrix was basically shells with fossil specimens. This was an extremely interesting matrix to search because of the large number of mammal and small reptile specimens. It also contained a good amount of amphibian specimens which I haven’t seen before in matrix. There were marine specimens also like fish specimens but the shark teeth were pretty beat and there were only a couple of ray specimens. Julianna has made extensive posts on Merritt Island micros. This post does contain some additional/different examples of specimens from the matrix. http://www.thefossilforum.com/index.php?/topic/57198-merritt-island-florida-pleistocene-fossils/ http://www.thefossilforum.com/index.php?/topic/59507-merritt-island-florida-pleistocene-fossils-part-2/ http://www.thefossilforum.com/index.php?/topic/60385-merritt-island-florida-pleistocene-fossil-photos/ If you mouse over the pictures you will see the file name which has the specimen size and my best effort at identification. If you can identify anything further or you see id errors please contribute to this post. Below is a gem jar display which shows some of the nicer specimens that I found. Clique the photo to see an enlarged version. The gem jar cups are 1.75 inches in diameter for size reference of the specimens. This is what is in each gem jar: 1 Lizard and snake vertebrae 2 Lizard and snake vertebrae 3 Interesting specimens that I need to id 4 Lizard jaws, mostly anole 5 Salamander vertebrae 6 Mammal teeth 7 Mammal teeth 8 Amphibian jaws (or don’t look like lizard) 9 Frog specimens 10 Mammal bones 11 Crab claw tips 12 Fish specimens (jaw fragments, teeth, scales, otoliths, and vertebrae) 13 Claws 14 Scales/Diodontid tooth plates 15 Ray tooth and barb 16 Scale/turtle shell fragments Below are some pictures of some individual specimens Ray: I found a single Dasyatis tooth: Fish: Otolith: Drum Tooth: Fish jaws/plates: Continued in the next reply.

  7. Here are five new claws for ID please. These were all found in TFF member Sacha's new Merritt Island, Florida Pleistocene matrix. I have included the first one I found here again for comparison. Auspex said the #1 is "from a small species, possibly as small as a least bittern." There were several more claws in the matrix, but these were the most complete samples. It would be great if I could get IDs for them. Thanks for looking. 1 2 3 4 5 6
  8. After researching my more obscure fossil finds from Sacha's Rattlesnake Creek matrix, I am left with these four that I am not sure of. (E. Miocene - Coosawatchee Fm., Hawthorn Group.) Please have a look, and let me know if anyone has any ideas. Thanks for looking. 1) 2) 3) 4)
  9. I found this broken tooth in Sacha's Rattlesnake Creek matrix. I am wondering if it is from an alligator, or even a croc. Seems way too big for a fish tooth. Any help would be appreciated. Scale is in mm. Thanks for looking.
  10. I just found this tonight in TFF member Sacha's Rattlesnake Creek matrix from Gainesville Florida. I took photos from both sides, top and bottom, and the joint end. Thanks for looking. Julianna
  11. I found this broken tooth in TFF member Sacha's Gainesville, Florida matrix. I thought this one looks like a cow shark. I compared it to the examples sent to me by sixgill pete, and I can't see a difference. I don't see any serrations either. I am hoping it is not another fragment of some other kind of shark tooth, but I'd really like to know. Thanks for looking.
  12. I found this tonight in Sacha's Rattlesnake Creek, Gainesville, Florida matrix. I know there is some Eocene in it as well as the more recent.
  13. I have been searching some matrix for micros from the MM quarry at Belgrade NC. Late Oligocene. I have lots to post but decided to start with the gastropods as I am without a clue on IDing these. ( I really need to spring and get the new volume from the NC Fossil Club on Fossil Mollusks) There are also a couple ray teeth and a cool bivalve. Looking at all of these by eye you cannot see the wear/damage. The usb microscope I bought is very cool. Takes great pictures with its 2 megapixel camera. First the Gastropods. 1- 5.73mm 2- 5.19mm 3- 4.97mm 4- over 6mm 5-3.26 and 2.51mm 6 - 5.98mm 7- 5.25 to over 10mm
  14. Here is the summary of my finds from the Florida matrix sent to me by TFF member jcbshark. It is his famous Cookie Cutter matrix! It contains fossils from the Miocene thru Pleistocene. Thanks again Jeff for this great matrix. I was very pleased to find these three Isistius teeth. Here is a selection of the shark teeth from this matrix. continued in the next reply
  15. I finally finished sorting and photographing my Rattlesnake Creek , Florida matrix finds. This matrix contains Miocene - Pleistocene fossils and some Eocene. Thank you Sacha for sending me this matrix. There were a lot of good finds and I had a hard time deciding which to show here. I don't have IDs for everything, and some I do might be wrong, so please feel free to correct me. I am here to learn. I found numerous ray teeth. Here is some of the ray material; Dasyatis Rhynchobatus male Dasyatis stingray spines continued in next reply
  16. Here are some of my first finds from the matrix sent to me by member Sacha. It is pebble matrix from the Rattlesnake Creek in Gainesville, Florida. Mostly Miocene. The colours of the teeth are really nice, and the preservation is excellent. I have attempted to ID what I can, but please correct me if I am wrong. First, here are some shark teeth. I think that 'A' and 'D' are Carcharhinus. not sure about the rest... Again, I think 'A', 'D', 'E', and 'I' are Carcharhinus. I had to add this one just to show the great colours! I realize that these are probably too worn to ID, but 'C' looks like a Hemi. Some of these teeth are almost translucent. I already know 'E', and 'F' are Lagodon, as I have found one of those before. And the crushing teeth are 'A', 'C', and 'D'. 'B' and 'G' are new to me tho.
  17. Hello, I was sorting through some gravel John (Sacha) so kindly sent to me, which I wanted to share some teeth I found and possibly get some IDs/confirmation on them. Thank you in advance for taking the time to look at and respond. My apologies if these are not the sharpest pictures, these micros can be difficult to photograph without a digital microscope with a good image capture. The first tooth I think maybe a basking shark tooth, based on photos I seen on the internet of basking shark teeth from Sharktooth Hill. However, the photos seem to vary by formation (species?). The second tooth looks like some sort of fish tooth, however I have no clue from what genus/species. It has the most amazing colors I have seen on such a tiny tooth. Any information would be helpful. I have included a side and bottom view of the tooth. The last tooth has the unmistaken look of a Hemipristis Serra, but I have never seen one so small (approx. the size of FDR's ear on a U.S. dime). I have included a photo of some of my little Lee Creek (Aurora, NC.) Hemipristis (Serra and Elongatus) next to the Rattlesnake creek tooth for relative size difference. If this is a Hemi, like it appears to be, is it from an unborn shark? Thanks again for taken the time to read through my post and examine the pictures!
  18. Hello Everyone, I was hoping someone could help me identify two teeth I found in some Lee Creek reject material I brought home from the Aurora Fossil Festival this year. Both teeth are approximately 1cm in length and have rather large roots for their small size. Here is the first tooth: At first I thought maybe a whale shark or possibly a basking shark, but really have no clue. I'm hoping one of the experts could give me a positive ID. Sorry if there is not enough detail in the pictures above to make a positive ID, these little micros are hard to shoot. Here is the second tooth, which I really have no clue what it could be. Thanks in advance for any assistance with the IDs.
  19. Like many people here in eastern NC my first full fledged exposures to fossils was at the Aurora Fossil museum. Growing up here, I had seen and found my share of smaller sharks teeth and "petrified" clams as we called them, but never thought much about it. Never had anyone able to expose me to the world of fossils.(Plus, I was much more interested in baseball ..... then girls.) After I had grandkids a friend said, hey you should take them to the fossil museum in Aurora. So I did and the rest is, as we say, history. I was amazed at the teeth and everything else that was on display there. The first day in the piles there my grandson Nick(who I hunt with regularly and the one who coined me sixgill pete) found a 2 plus inch meg and a 2 plus inch mako. We were hooked. We went back to those piles tirelessly, as often as we could. We found huge numbers of mako's and tiger's and some megs and some cow sharks. Everything the piles had to offer. Then I got into the mine, wow, I found some amazing things in there, my favorite being the cow shark teeth. But there had to be more, so I found GMR and then all the MM quarries here in the eastern part of NC. Did research and found out about the beaches and rivers and much more. Then I discovered micro's and as many of you know, they are among my favorites. Beautiful little things the eye can barely see, but amazing and in many cases some of the rarest teeth. I also discovered shells, and echinoids. Then came The Fossil forum. Without a doubt, the finest fossil site on the web, great people and a plethora of USEFULL information. And the knowledge here is 5 star A+. I have learned so much and continue to learn everyday I am able to log in. I recently was able to get my first trilobite from fantastic forum member xonenine. Here in NC, there is no where to find them. My collection has come along way since its humble beginnings. So here are a few highlight's of it, some of my favorite pieces. Don a.k.a. sixgill pete my first big meg, 4 3/8" from GMR a 2 1/8 lower hastalis from Lee Creek two upper hastalis 2 1/8 and 2 3/8 from Lee Creek my two favorite rics a beautiful gun metal blue perfect 2 1/16 and a very rare parasymphyseal, both found on the same day at the Onslow Martin Marietta Quarry From GMR a very nice about 1 1/4 Great White in matrix Also from GMR a 2 1/2 inch great white
