  1. Trilobite ID

    Hello. Can somebody ID this one for me? I bought this trilobite from a seller in China via online site. I don't have the location or the formation.
  2. I am just wondering. Have anyone on here found microfossils from Flowerpot Shale/Formation? The age is Permian. I dug up a few kilograms of micromatrix from this formation in Woodward county, Oklahoma a couple months ago. I'll be using this topic to post any finds as time goes: although it would take me several months or years to go through it completely, depending on how busy I am. I still have three other different micromatrices to go through.
  3. Hello all! Any insight on this unidentified fossil, from Eastern Arizona, Chinle Formation, would be deeply appreciated. I'm presuming it's a partial phytosaur jaw, but I really have no idea. Originally from a family who collects on their private ranch. Please see images, which includes extreme close-ups. [P.S., this is the 2nd of 5 specimens that I'm posting for ID today; I deeply appreciate any insight that you can provide]. With gratitude, Ryan
  4. Probably a sponge but....

    This was found among one of the large chert layers in the permian Kaibab Limestone. The sponge, Actinocoelia, is very common in this layer but this seems different or is at least a different presentation or segment of it. It's nearly perfectly round. It's diameter is 3 1/2 cm.
  5. Found this nautiloid. Preservation not so great (but you can see septa) but the colors are awesome!
  6. Kaibab Limestone fish spine?

    Found this in the Permian Kaibab limestone today. Fish spine? The last photo shows a cross section of the mold that it seems part of.
  7. Permian fossils?

    These aren’t exact examples, but they’re very good representations as to what I mean- -Is it rare to find Permian fossils with that bone colored white glossy surface patina, like right here?
  8. I finally finished going through my Oklahoma Permian Matrix from PaleoTex LLC! SO MUCH STUFF! I went through it the first time just with eyeballs (with the help of reading glasses). Then I realized I should use my microscope camera (which runs through my computer which is AWESOME) and see if I missed anything. OH MY GREAT GOOGLY MOOGLY I missed a lot! So here are some of the really "minis" from the matrix! Most are so small that it just couldn't even get a pic with my scale, some are less than 1 mm - a speck of dust! . I need to get a millimeter scale, though, for sure. So here are some more finds from the Oklahoma Permian: Mycterosaurus tooth : 4 mm Chevron Bone (part of the tail of an amphibian, I believe? 4 mm A Doleserpeton toe bone! So very tiny. You can see how small it is compared to the 4 mm chevron! I think this is an intervertebral thing? 2 mm Unknown tiny tiny. Can't seem to find out what this is, but I thought it was really really cool looking . It was literally the size o a speck of dust.... which sadly meant I lost it after I photographed it....it just disappeared. a lovely bone. 3 mm Jaw plate...i loved the blueish enamel: 3 mm Same with this "blue tooth" - probably Cacops, I think? 3 mm Another Cacops tooth: 4 mm An unknown jaw fragment: 3mm Captorhinus tooth? 2 mm Doleserpeton jaw plates biggest 2 mm and lastly a Diadectid tooth There are so many more little bones and teeth and jaw plates and vertebras and skull fragments!! Needless to say, it's been great fun looking through all this tiny matrix. i am totally hooked on it!
  9. Heres' are some Kaibab Formation nautiloids I found this weekend.
  10. From the album fish

    Amblypterus macropterus Permian Odernheim Germany
  11. Hello, a bunch of Permian trace fossils that I am interested in buying as a bulk order. Before I can confirm, if anyone could take a peek and let me know that they seem ok, that would be great. All from French locations--but correct spelling may have been jumbled in autotranslate. I'm planning to buy the lot, but if anyone spots anything amiss, if you could let me know, that would be great. They do resemble other similar fossils I've seen for sale online. 1 - Dromopus lacertoides -- Lodeve France 2 - Anthichnium salamandroides - Lodeve France 3 - Anthichnium salamandroides 2 - Lodeve France 4 - Salichnium pectinatus - Lodeve France 5 - x3 ripple marks - Lodeve France 6 - Traces of raindrop - Lodeve France

  13. Hi everyone! Inspired by @JamieLynn, I purchased some micromatrix from our favourite auction site a couple of months ago. It finally arrived last week, and after going through it once, I've found a few little goodies that I'd like help in identifying. I'll also tag @Bobby Rico because I know that he has searched through this stuff in the past, too. The fossils are from Richard's Spur in Oklahoma and they are Permian in age. Perhaps @jdp and @dinodigger can also have a look (especially at #1 and #5)? I appreciate any help you can give! Thanks in advance! Monica Item #1: I think this might be a tooth from Cacops sp. (amphibian) Item #2: I think this might be a piece of jaw from Captorhinus aguti (reptile) More to come...
  14. Ichno fossil ID help

    OK, looking for some help with this ID. I THINK this is a lungfish burrow, but I've never seen any before. I'm exploring a new property permission for a Permian Vert site. The reports also describe numerous lungfish burrows, some with the fish still inside, although most are just the trace fossils. This bit of shale has one every few inches and they are roughly 1" - 1.5" in diameter. So whats your opinion?
  15. The Great Dyings time

    Just found this about the Permian extinction/the great dying, earths greatest mass extinction. https://www.artsci.utoronto.ca/news/geochronologists-shed-light-earths-greatest-mass-extinction
  16. Kaibab Sponges & Other Fossils

    I took my first long trip (more than 15 minutes) to search for Permian fossils in the Kaibab Limestone of central Arizona near Pine. I have previously only collected silicified fossils that had been transported south of the Mogollon Rim by streams. The Kaibab is known for two silicified fossils that are great index fossils for the Leonardian (Kungarian) Age across western US: Peniculauris bassi, a brachiopod and Actinocoelia maeadrina, a sponge. At first I was disappointed because I have heard that you could collect hundreds of each type in a short period of time. However I found a couple of sponges with the best 3 D texture that I have seen on the internet. They each are each about 13 cm in length. I will take quality over quantity any day. The Peniculauris bassi brachiopod is about 5 cm wide. I also found some very detailed echinoid spines (3.5 cm field of view). I will have to go back to the top of the Rim to collect more types of fossils. I only have a few hundred square miles of Kaibab to search, exclude that near the Grand Canyon. Good reference on Actinicoelia maeadrina: Griffin LR (1966) Actinocoelia maeandrina Finks, from the Kaibab Limestone of northern Arizona. Brigham Young Univ Geol Stud 13: 105–108 http://geology.byu.edu/home/sites/default/files/actinocoelia-maeandrina-finks-from-the-kaibab-limestone-of-northern-arizona-leland-r.-

  18. Dimetrodon tooth?

    At 8mm, it seems small to me. Any thoughts? From the Texas Red Beds.
  19. Dimetrodon Tibia

    Here is a beautiful young Dimetrodon tibia- wonderful thick permian pond clay helps preserve wonderfully. Short back legs much like a horned toad. Watch a horn toad run and you will get the idea of how these guys ran. Fast, but short, bursts of speed for surprise attack.
  20. Dimetrodon's yay!!!

    Dimetrodon teeth have come up lately and I havent posted in a long time. This specimen is grandis species from the Arroyo formation. Older species are smaller and have interesting fluting, something we don't typically see in the later, more advanced guys who also have larger, more robust teeth with coarser serrations.
  21. Tracking Traces of Permian Coast Life

    Here is a short trip to keep those of us still in quarantine entertained. I collected this before our quarantine started. Something I have wanted for a while ever since seeing one but was not able to collect was in my trip through Utah's Paleozoic (link here: ) is a trace fossil called Skolithos. For those without much experience with trace fossils, Skolithos is a vertical tubelike burrow in sand on a sandy high-energy beach. The little critters would have to dig relatively deep vertical burrows so that they weren't washed away the next time a storm rolled through. A common name for this particular trace fossil is “piperock” because the number burrows could get dense enough in one area that the rock looks a bundle of straws. Just like a lot of trace fossils, it is not certain what made these burrows but it is known that it probably went extinct at the end of the Cretaceous as there are not any specimens after the dinosaurs’ doomsday. My particular specimen is made of calcareous sandstone that has been slightly metamorphosed into a quartzite. It is most likely from the Lower Permian of the Oquirrh Group based on the location and the nearby rock formation it appeared to have fallen out of but I found it in a gravel pile from the shoreline of Lake Bonneville so the exact stratigraphy is unknown.
  22. I picked this up a while ago from the yard of a rockhound who is now deceased, but they could not tell me anything about it at the time anyway... all they could say was it was likely collected somewhere here on Vancouver Island, which would make it either Triassic Parson Bay/Sutton or Quatsino Formation, or Pennsylvanian/Permian Mt Mark or Buttle Lake Fm. I don't think it's likely to be from any of the younger formations. These structures look suspiciously like sponges to me, but I can't say for sure. They've obviously been silicified, which makes ID difficult. Any ideas? I noticed the feature marked with a red circle while looking thru the photos. It might be indicative of ID or maybe I'm just seeing things. I've not bothered to shrink the photos, as I want people to be able to see whatever detail there is on this thing. Hopefully they will load... I'll post one at a time if I have to.
  23. I was wondering if there are any permian to cretaceous reptile/amphibian fossils that even an newbie like me can acquire without having to dig or pay a huge price for,I looked for permian and triassic stuff and it is really hard to find such things Are barasaurus legal to buy?
  24. I posted some of my finds from the Texas Permian in the Box of Matrix I got from PaleoTex LLC and now I get to share some of the cool little stuff I've found in the Oklahoma Permian! Texas Permian had lots of sharks teeth, Amphibian teeth and interesting boney bits. The Oklahoma stuff is not nearly as "productive" as the Texas Red Bed matrix, but it has LOTS more complete bones and vertebrae! And some really nice little jaws with teeth! Here are a few of my favorite finds. Most are about 1/4 inch, some smaller, a few a bit larger. Amphibian Bolterpeton Jaw and teeth 1/4 inch Amphibian Captorhinus aguti Jaw and Teeth: Synapsid Mycterosaurus Tooth and Jaw Fragment 1/4 inch Unknown Amphibian Skull Fragment (the two round knobs are where the vertebra attached) 1/4 inch Another Unknown Amphibian Skull fragment: 3/8 inch LOTS of little bones! A nice full rib Vertebraes: Myceterosaurus Caudal Vert: 1/4 inch An interesting Vert that looks like an old Victorian Door Knocker! hahaha Probably Captorhinus 1/4 inch Another Captorhinus Vert 1/4 inch An unknown Vert: 1/8 inch
