  1. Hello These are the adventures of myself and my dog Millie as we hunt for fossils and history along the Peace River. Our mode of travel is our 12’ Indian River Canoe, Balance. Im a 4th generation Polk county native, and Millie comes from a long line of Colorado ranch dogs. We do everything together. Including work, as I am a farrier for my day job, and the farm owners are more excited to see Millie than me! The goal of this journal is to document the learning along with the adventures. To go below our sieves, and learn why the river is presenting as it is. Other members have already posted pictures and info on every fossil I’m likely to find, but the river can still teach me/us why the hole I’m digging is delivering specific materials. Understanding what happened before what happened, happened. That’s what I want to know! Millie and I have been gifted this river and the ability to run it at a moments notice. That’s not the case for everyone. Even with access I still only get out for a morning or so a week. So this journal will also provide an avenue for those who can’t just jump in the boat with us. Jump in through this forum and help out along the way when you can/want. The more we learn the better the treasure!! Jp & Mille LET THE ADVENTURE BEGIN! Season opener - Oct 2023 water depth day of - 8’ and falling. Like most things I’m impatient about, starting Fossil hunting this year was rushed. Millie and I ran head on into a river that’s a solid 3’ too high for me to handle any real working conditions. There’s places to work. We just haven’t found many at these depths! Yet!! After work arrived and we got started towards the river. Late arrival and definitely some dark water running ahead but at this water height you just gotta keep the boat in the middle. Got in late but just in time for a welcome back from the Peace! We woke up ready! Well, I did. Camp and my “Field Office” ready. Now to get wet! Because of the water depth I tied leashes to all the heavy tools and tied some extra pool noodle to them. That way I could drop them and just pull up the leader. Brought the “Velvet Touch” probe. No stopping us now! “What” I was after wasn’t an option this trip. I had only two available spots in mind that would be under 4’ deep. Both those spots are in a very recent deposit that I’ve been getting lots of Pleistocene and some Pliocene mammal material from. I ended up finding the time frame expected, and possibly an extinct sand shark nursery area. The river had sifted one spot completely away during the last flood so I was left with only one place to put in effort! At 4’ it was at my cap for height. I’m 5’6’’ and I could only dig 2 feet down before I ran out of shovel. So I had to figure something out. First I tried to fill the sieve on the River bottom and lift it up. FAIL! never got it to stay put long enough to do anything productive before I’d loose it and it would pop up down stream pulling on the leash. Next I tried to lift the gravel to the sifter on the surface. There was so much water the shovel load was gone before I broke the surface! FAIL! At a max depth of 2 feet down I wasn’t going to be learning much about the geography or layers I needed to work through. So I shifted gears and decided to focus on just the top 2’ as effectively as I could. The third try ended up succeeding. I would loosen the riverbed into a loose filled hole that had collapsed on itself and then use my scoop on a pole thing to transfer the loose material up to the surface. Not the best method but I’m grateful to have been able to stand there all day. I’d work forward 3’ and over 1’ then back again. All at 2’ or less deep or I’d go under. I suppose if I feel like moving a bunch of river bed again we could come back here and go deeper! One of my questions about this area is what is it old enough to find within it? Another trip! Here’s the gratuitous highlights shot! Not a bad day! The alligator tooth got a yell but the sand tigers and mammal teeth got me really excited. Millie and I were exhausted and COLD! I learned a few things this weekend to put in the journal. Before that. Let’s eat! Steak for me and steak for Millie. Yumm. Lessons: 1. I need appropriate clothes. Like wet suit stuff. Can’t be under water like that all day again. I got chilly and had to warm up several times. 85deg out too! What I wear is fine for knee deep wading but definitely time to upgrade the wardrobe. (I did try my new dive boots and that was the only part of me that wasn’t cold) 2. Regular shovel handles are way too short. Amend as needed to your stature. I need a 12’ handle to dig a hole in this water. So I’m out! 3. Jack, (Shellseeker) is insane!! This was my first time hunting this deep and it’s right in his sweet spot. You’re an animal! He tried to assist my tool tuning but until you run out of shovel that’s a new feeling to adjust to. 4. At two feet deep this area is where I will come for younger land aged fauna and I can expect the standard peace river sharks teeth assemblage with a higher than usual volume of sand sharks teeth. This was a great day hunting and I learned a lot. Maybe not about what my intended question was or the areas I’ve been thinking of but a ton about gear and technique! KEEP THE FAITH AND TRY TO DO GOOD!! Jp & Millie Here are the finds from this trip and some info used to figure out the unknowns. sand shark and some Hemi Serra Peace River mix fun and unique things - The mammal molar ended up being a Giant Tapir. By shape and size 3rd or 4th premolar. No root. Should have given it away. Mixed bag bottom to top of left- Gator tooth gator tooth Crappy Barbra’s incisor Canine- size 22mm broken suggest coyote or smaller domestic dog. 25mm would be the target. Tiny molar - it’s broken but by the face and measurements it’s most likely a rodent. Camel type tooth frag. Upper right - various tiger shark species to identify with Florida fossil hunters PDF middle - two deer horn buttons. One I already had but these were found 5 feet apart. Same deer?!? Bottom right- Eocene snail and crab shell fragments. Those are 37.5 Mya.?? Snail identification was general to the Ocala formation results of similar snail species.

    Brule Formation Carnivorous Mammal Tooth

    I recently saw this carnivorous mammal tooth from the Brule Formation for sale. It is labelled as being that of a Hesperocyon gregarius, but what little I know of carnivorous mammal dentition leads me to believe that the tooth could in fact come from a Hyaenodon. As always, I've decided I'm going to play it safe and ask someone of greater expertise to verify this. It is my understanding that @jpc, @Randyw and @ParkerPaleo are all Brule Formation specialists, so I will take the liberty of "@ing" you all in. Thanks in advance for any guidance Othniel

  6. So this happened back in late March and I’m just now getting around to posting (or boasting?) about it. At this years gem and mineral show in Loveland, Colorado I entered a display case of White River Formation fossils which I have collected mostly in Colorado over the last few years. I emphasized diversity, attempting to show the diversity of the organisms (or at least prominent organisms) in the ecosystem while aiming to educate show visitors about the under-appreciated Eocene to Oligocene transition. Over 4,000 people came to the show, and at the end of the weekend the judges selected my case for first place in the fossils category, which I was very happy with because there were some other really awesome fossil displays people had put together. For the win I received a trophy and blue ribbon. I definitely intend to display again next year at the same show!

    I'm very belated with this report, but it took until today to finish all the prep work on the pieces I picked up on this trip. This time was fun and quite productive, I went out with my brother and 2 of our friends. None of them are of the fossil hunting persuasion, but they enjoyed it nonetheless. This Liracassis apta was a great opportunity to test out the chisel attachment on my new air scribe.
  8. Found a carbonized plant fossil in Sespe formation conglomerate stone in the Matilija Canyon area of the Los Padres Mountains of Southern California. Likely something from the Horsetail family or something in the bamboo family. Based on the below report, these rocks are likely from the Oligocene or Eocene periods. The area has mostly Marine fossils but this was probably a land plant that washed out to sea and was deposited along with other flood debris on the shallow sea floor.

    Chandler Bridge "Micro" teeth ID

    I have been working on sorting teeth I've collected from the Chandler Bridge Formation (Oligocene, ~28 MYA) from one site by species. I've not put adequate time into learning how to differentiate the smaller teeth such as these, and am working on filling those gaps in my knowledge. Here I have isolated 6 "distinct" types of teeth that I am attempting to put a name on. Apologies on the photo quality, I was in a bit of a rush, hopefully there is enough detail to understand the general characteristics I am attempting to distinguish between. 1. Wide root, flat and, typically, curved to one side. Is serrated from where the enamel meets the root all the way down onto the blade. 2. Wide thin root, thin straight blade, serrations. 3. Almost identical in shape to number 2, except straight blade with no serrations. 4. Larger teeth in general compared to the others, curved and straight blade with nos errations, has enamel "wrinkles" similar to serrations near the root only. 5. Very stubby root (horizontally compressed and somewhat more bulbous than the other teeth). Long, straight blade with no serrations. 6. Smaller in general than the other teeth. Serrations along root, but not on the blade. Blade is slightly curved. These are my proposed identification of the teeth: 1. Reef/Requiem shark upper teeth of some kind 2. Unknown 3. Lemon shark lower lateral teeth 4. Lemon Shark upper teeth 5. Lemon shark lower central teeth 6. Requiem shark lower teeth
  10. Hi, appreciate any ID help on this one from Chivo Canyon in Southern California. About 4-5" in diameter found inside of a roughly 1 foot diameter rock. The area is known for Eocene and Oligocene period fossils. Guessing this may be a sponge, coral, or possibly echinoderm like a Sea Urchin. Stumped on the ID so far. Most of the other fossils in the canyon are mollusks and gastropods. Thanks! -Chris.
  11. Just posting some pics of some finds from Chivo Canyon from 2020 and 2024. Would really appreciate any ID inputs on the Unknown Fossils especially the roundish one with many circles in it. It was roughly 4-5" in diameter in the center of a roughly 1 foot diameter rock. Guessing Sponge, Coral, or may an Echinoderm like an Urchin. The Chivo Canyon area is known to have fossils from the Eocene, and Oligocene periods. There are also a couple other unknown fossils which could be bones but not sure. The Tower Snails or Turritellas are probably mostly Turritella Uvasana. I don't know what the other Gastropods are. Thanks in advance for any ID ideas! -Chris.
  12. I am excited to finally announce my first contribution to science! This is a section of dentary/beak of a Pelagornis cf. sandersi from the Ashley Formation in Summerville, South Carolina. This was found in December 2023 and has been donated to the new Charleston Center for Paleontology, where it will reside in their collections. A paper featuring it and other Pelagornis sandersi fossils from the area (which there aren't many of) is in progress. Here it is after prep:
  13. In the U.S., Otodus angustidens teeth seem fairly common (primarily from South Carolina). From scouring the web, it looks like O. angustidens can also be found in at least in a few other countries, including Australia, Germany, Kazakhstan, and Mexico. However, I very rarely see these pop up, whether it's for sale or otherwise. In contrast, I see other members/stages of the chronospecies--obliquus, auriculatus, sokolovi, chubutensis, megalodon--show up not infrequently from multiple locations around the world. Is this because there are fewer accessible Oligocene-aged marine deposits globally, more restrictions on fossil collection and/or export where these deposits do occur outside the U.S., or for other reasons? Do you know of any other countries besides those I've listed where angustidens are found? If you have any non-U.S. angustidens teeth in your collection, please also do share photos! This is the only non-U.S. one I own, from Baja California, Mexico.

    1.5 inch lamnid type shark vertebra in matrix from the New Bern quarry. Not sure if this is from the Oligocene River Bend Formation or the Eocene Castle Hayne Formation. If you think you recognize which formation this is from, leave a comment.
