    A Fossil A Day.....

    A Fossil A Day....keeps the blues away! Or something like that... I started an Instragram account (jamielynnfossilquest) and am posting a fossil a day, so I figured I should do that on here, to REAL fossil enthusiasts! I'm a few days behind, so I will start out with a few more than one a day but then it will settle down to One Fossil (but I will admit, I'll probably miss a few days, but I'll double up or whatever.) I'll start with Texas Pennsylvanian era, but will branch out to other locations and time periods, so expect a little of everything! So enjoy A Fossil A Day! Texas

    Secodontosaurus tooth?

    From the album: Permian

    Teeth from the Permian are often difficult, nigh impossible to identify with confidence. This tooth is strongly carinated, with the carinae proceeding to the base of the crown. It has no labio-lingual curvature and an irregular enamel texture. My best guess at the moment is a synapsid, something like Secodontosaurus.

    Actinopterygian fish teeth

    From the album: Permian

    Actinopterygian (ray-finned) fish teeth from the Early Permian of OK (Wellington Fm.).
  4. ThePhysicist

    Amphibian tooth

    From the album: Permian

    An amphibian tooth from the Early Permian of OK (Wellington Fm.). They can be differentiated from similar Actinopterygian teeth by the lack of a conical acrodin cap (translucent tip), no "S" curvature, and basal creases which terminate well before the apex. The exact ID is uncertain, but it could be something like Trimerorhachis.
  5. ThePhysicist

    Lungfish scales

    From the album: Permian

    Rhipidistian (lungfish) scales from the Early Permian (Wellington Fm., Waurika, OK). They can be identified by a "honey comb" structure on one side, the other is largely featureless.
  6. ThePhysicist

    Arroyo formation sandstone

    From the album: Permian

    These sand grains were deposited by a river in the Early Permian of what would be North Texas. Iron oxides (e.g. hematite) color these sediments red (they weren't originally).
  7. ThePhysicist

    Arroyo formation sedimentology

    From the album: Permian

    Sandstone collected from the Arroyo formation (Clear Form Group) of North Texas. The color transition represents a transition between a river deposit (red) and a floodplain deposit (white). See "Geologic Guide of Baylor County, Texas"

  10. There are few reasons why I would ever wake up at 5 am and begin a two and a half hour drive out to the middle of nowhere. When I saw that the PSoA was heading out to the Brownwood area, I knew it was an opportunity too good to pass up. Everything I had hunted prior might as well have been buried yesterday when compared to the mind-blowing ages of Pennsylvanian and Permian rocks. It's still crazy to think that those formations were roughly three times the age of the oldest stuff I'd seen before. When I peeled out of the parking garage to begin my drive under the stars, I didn't feel an ounce o

    Two Nautiloid Steinkerns?

    Hello, Could I get some help identifying these two nautiloid steinkerns? Unfortunately no precise age/locality info on them but I think they might be from the Pennsylvanian or Permian of Kansas or Texas. They are both around 8-9cm wide. 1. 2. Referring to this: http://inyo2.coffeecup.com/kansasfossils/kansasfossils.html I think #1. might be Metacoceras and #2. might be Liroceras. @Missourian I believe you are referenced in that post and you seem to be experienced in this fauna? Thanks

    Pennsylvanian/Permian crinoids

    Hello, I have a whole bunch of unidentified crinoids I'd like some help identifying. From my guess on the species and the fact that there were all together (as well as the other specimens that came with it), my guess is that these are Pennsylvanian or Permian-aged crinoids from Texas or Kansas. I'm hoping narrowing down the ID would better pinpoint the provenance for them. Here goes. The calyxes all range from 1-2 cm wide. I did attempt to ID them, using resources including this by the forum's @Missourian: #1-#4 I think are all of the sam

    Reptile Oklahoma?

    Hello everybody I am a bit worried about the fossil I show. We got it many years ago and do not know much about it. As I remember it should come from Oklahoma, Permian. Reptiles. That´s it , nothing more. In my brain are some reminds name could starts with "R" for the Animal, but... What do you think? thanks for support!

    Texas Red Beds

    From the album: Permian

    Some of the famous Texas "red beds" deposited during the Early Permian in streams and rivers, seen near Seymour, TX (member of the Clear Fork Group). Iron in the sand oxidized, giving the stones their eponymous color.

    Orthacanthus serrations

    From the album: Permian

    Orthacanthus (a Xenacathid Chondrichthyan) have squared-off, irregular serrations - distinct from those on say, Dimetrodon.

    Orthacanthus bite marks

    From the album: Permian

    I commonly see bite marks on many of these fossils. Some like those on this Orthacanthus cusp were likely made by serrations raking across the surface.
  17. These were both labeled as Dromopus "Marsh" (seller mistook discoverer name for species). While the larger prints do seem to look like Dromopus to my amature eye, the smaller print may be something else. Both were consolidated with Elmer's glue (explaining the glossy appearance).

    From the album: Permian fossils from Rheinland-Pfalz, sw-Germany

    a rare, 30 cm wide stromatolite from a closed site in Rheinland-Pfalz-Region. Permian age, showing fantastic internal structures
  19. Hey everyone, I've been recently reading through Mark McKinzie's book, Oklahoma Fossil Localities. It's got tons of useful information and has been inspiring me to plan out some future trips across the red river once I'm back in DFW. Hunting for Permian micros in Waurika is at the top of my list, but I have a few questions about the main site and surrounding road cuts. If anyone could reach out to me via PM to discuss Waurika, I would greatly appreciate it! Thanks

    Permian trilobite

    This trilobite tail was identified as Ditomopyge and Permian in age. It's from the Saddle Creek Limestone in Texas. I'm curious if it is Permian an age or if it is an early time period.

    Help IDing Permian Age Fossil

    Found this really weird fossil the other day while hunting for brachiopods. It comes from Permian limestone marine/coastal deposits in Dona Ana County, NM near Hatch. The area is a brecciated limestone field. I've collected coral, brachiopods, crinoids, gastropods, and echinoderm fossils from here before, but they aren't always the best preserved. This rock contains fusulinids, she'll fragments, crinoid bits, and echinoderm spines but I have no idea what the large... interesting looking.... fossil is. It appears to have some enamel left on bits of it, so
