Fossilized Dad Posted July 22, 2021 Share Posted July 22, 2021 Hi Everyone, My 10 year old daughter and I went to the Peace River and found lots of fun stuff, including turtle shell, bones of many kinds, probably a couple hundred shark teeth, some horse teeth, and then a few mystery items. Images 1 and 2 show what looks like some type of body armor--didn't seem to match glyptodont, so we are puzzled. Image 3 shows a large predator tooth of some kind. Once again stumped. In images 4 and 5 you can see the tooth is in two pieces. I found the first piece in one seive, then in just the next seive, I found the second piece and they matched up perfectly to form a 2" piece of a large tooth. Doesn't seem like dire wolf or a big cat. Don't think it's dolphin as most specimen were around 1". Perhaps whale? In Images 6 and 7, we think it may be a beaver incisor that is broken and is missing some enamel. The part of enamel that is showing is tapered to a worn point. Images 9 and 10 show another unknown. We aren't clear on what this is. Image 11 shows all the pieces together on a darker surface, so more details may show up for you. What do you think? Any ideas would help as we've looked through our fossil books and on the internet. thanks, Lloyd Link to comment Share on other sites More sharing options...
Harry Pristis Posted July 22, 2021 Share Posted July 22, 2021 Welcome to the Forum, Fossilized Dad. You'll get more response and reliable IDs if you post clearer images. Do you have editing software that came with your camera or with your scanner? Use the image-editing software (or download shareware from the Internet). You can be as creative as you want to be with the editing software, but the following basic things will improve anyone's images: GROUP IMAGES of more than a few fossils are not effective. The more individual fossils in an image, the greater the amount of table-top is in the image. Viewers cannot see the details of a fossil that might take up less than five percent of the total image. Photograph a single fossil (or two or three, if they're tiny), and post that image. DON'T OBSCURE details of the fossil by pinching it between your fingers. If you want to use fingers to provide scale, support the fossil from below ... that is, on top of your fingers. To improve the focus, rest your hand with the fossil on a stable surface like a table or desk. SCALE is important. Provide measurements of your fossil in millimeters and inches for the widest audience. Don't use a coin for scale; there are many foreign subscribers who don't know your coin's size. LIGHT IT UP. Use as much ambient light as possible to reduce shadows...two light sources are a minimum. Eliminate yellowed images caused by tungsten filament bulbs by switching to the new compact flourescent bulbs. CFLs come in a "daylight" (6500K) version that you can use in any (non-dimming) fixture and produce very little heat. Some LEDs produce a near-daylight effect. ELIMINATE SHADOWS by elevating the fossil on a glass or colorless plastic stage a couple of inches above the background. Illuminate the fossil AND THE BACKGROUND in this configuration. There are numerous things around the house to use for this purpose, from scrap window-glass to disposable plastic food/drink containers. BRIGHTEN AND CONTRAST. BRIGHTEN the image until the fossil appears slightly washed, then adjust the CONTRAST until the fossil is bright and sharp and is a good color-match. Practice this until you get a feel for it. CROP, CROP, CROP. Again, use the image-editing software to crop the image to only what is pertinent. Leave only a narrow margin around the fossil. The more of your kitchen counter-top in the image, the smaller the fossil image will be. REDUCE THE FILE SIZE. The images directly from a camera may be too large for posting directly to a forum, or you may be severely limited in the number of images you can post. You can constrain the proportions of your image to produce exactly the size that works best (I routinely use 700 Kb - 1.0 Mb for my images now). I save in JPEG format. 1 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
Fossilized Dad Posted July 22, 2021 Author Share Posted July 22, 2021 Thanks for the prompt to make the images clearer and our apologies as we did hurry them last night to get them out for folks to see. Today we took the time to photograph them a little better. I'll attach them below. This is the tooth that I found in two pieces in two separate sifts. Here is the one that could be a beaver incisor as our best guess. This is some kind of scute, we think, but it's unclear as the bottom tapers and the top doesn't match osteoderm photos we have completely. This one is intriguing and a definite unknown. Finally, what we think is a barracuda tooth. It's about the right size (1/2"). Thanks everyone! 1 Link to comment Share on other sites More sharing options...
Harry Pristis Posted July 22, 2021 Share Posted July 22, 2021 The second object looks to me to be a fragment of enamel plate from a mammoth tooth. There is a bit of cementum still attached -- the highly polished stuff. The last object does appear to be a barracuda or wahoo tooth. What would enhance the chance of more identifications are lateral, basal, and broken-edge views. These would add perspective to a 2-dimension view of a 3-dimension object. 1 1 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
Fossilized Dad Posted July 22, 2021 Author Share Posted July 22, 2021 Thanks Harry, We never would have guessed Mammoth. My daughter is glued to the website awaiting replies and looking at other pages! Here are some more views of the tooth taken apart at the break--from above and below and also showing the broken middle. Here are two lateral views of the "armor plate" Finally two lateral views of the unknown fossil. Link to comment Share on other sites More sharing options...
Harry Pristis Posted July 22, 2021 Share Posted July 22, 2021 I can guess about one of these specimens: The "armor" is likely to be an osteoderm from a giant tortoise, Hesperotudo sp. 1 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...

We have had the summer rains and in most places , the Peace river is fast and deep, which makes it challenging even for the most experienced. Most people who attempt what you have done this time of year fail and sometimes get a negative impression of the river I love. I know it is challenging because I was out hunting yesterday and you matched most of my finds. Let me focus on your canine.. At a projected size of the full tooth at 2 plus inches, there are only a few choices.. It could be whale and even dolphin ( I have a couple of dolphin over 2 inches). I know a lot about whale/dolphin teeth in the Peace River, and this very unlikely to be whale. I think it most resembles cat... Jaguar or slightly more likely Puma concolor ( based on robustness). This is an opinion of someone who has found millions of fossils in the Peace River over 13 years.. Cat leads the possibilities at about 35% in my mind EDITED to add photos. I was considering these finds with my comments.

Seems like a logical choice. This is great. Agreed that this is a barnacle steinkern now that you’ve shown us. Not in our ID books. Thanks.

FranzBernhard Posted July 23, 2021 Share Posted July 23, 2021 Note to photography: It is relatively difficult to obtain good pics from very dark objects*. I for myself, I am generally using a nearly black background (well, its a black pant...), irrespective the color of the object photographed. There is not much contrast with dark objects then, but this does not matter to me. I find a dark object and bright background more disturbing. *There are methods to whiten the objects physically and reversibly, but this is a thing mostly for professionals. 15 hours ago, Fossilized Dad said: My daughter is glued to the website awaiting replies Congrats!!

Franz Bernhard It can be challenging to photograph dark specimens. The majority of my images are of dark-brown or black fossils, so IT CAN BE DONE by amateurs with a little care. All of my often-posted tips for making better images were conceived with that experience as background. I won't repeat the tips in this post; you can read them earlier in the thread.

Have you some of these fossils photographed on a black background and later put electronically on a white background? Franz Bernhard No, never a black background for a dark fossil. That's a good way to frustrate camera sensors. Backgrounds are light -- whitish to grayish. I like to elevate the fossil above the light-color background on a glass stage so that the background is slightly out of focus. (See my "tips.") Sometimes, usually for light-colored specimens, I may convert the light-colored background to a darker color for dramatic effect. 5 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
Fossilized Dad Posted August 17, 2021 Author Share Posted August 17, 2021 Hi Everyone, Many thanks to you all for helping us on our fossil IDs. We just posted another Youtube video about our time at the Peace River and thanked you in the video, those on the Fossil Forum who helped us, in the video. We will be posting several other fossil related Florida trips in the next coming month or so including some museum quality calcite clams from Ruck's Pit and a secret spot we found. Also found blue and red agatized corals from N. Florida/S. Georgia and some more fossils on the Santa Fe River. The link to the Peace River is below, in case you're interested. Please like and subscribe, if you can, because my daughter wants to be a museum curator/paleontologist/youtuber and we need all the support we can get! https://youtu.be/6RBWgpN7Vhg Lloyd Link to comment Share on other sites More sharing options...
Brandy Cole Posted August 27, 2021 Share Posted August 27, 2021 Harry Pristis would know a lot better than I do, but for what it's worth, I agree that the second object looks like a fragment of mammoth tooth plate. I found a similar small plate fragment just the other day. When I first started hunting, I thought any mammoth teeth fragments would be huge, and I didn't realize that because they are so big, it's not that unusual for them to break into much smaller fragments like this.
