    Waurika Permian microfossils

    Hello! I've recently been sorting through some Waurika, Oklahoma Permian microfossil matrix, and I've been able to identify most of my finds (As a beginner in the Permian field, @ThePhysicist's Permian album really helped me) but some I haven't been able to pin down yet. I'd really appreciate some ID assistance! Let me know if you need better photos, my photo-taking ability is, alas, subpar. 1. Trimerorhachis jaw perhaps? Or fish? I've heard distinguishing between the two is quite difficult. ~2 mm. 2. A really strange texture, I was hoping

    Chert fossils, inclusions

    Hello After doing some reseaech on some big Chert nodules given to me...I went back through some Chert that I found along the northern North Sea coast of The Netherlands... I really like Chert...I have always been curious about mineral inclusions and/or fossils in Chert...I am having trouble finding laymans info on the subject...the info I do find is a bit overwhelming... Im hoping someone could help me out identifying some of the things that I am seeing in my pieces...I have pointed to points of interest to me... I have posted the photos twice..

    Very unusual microfossils

    Hello everyone, Following the previous posts about other fossils found in the same marine upper cretaceous sediment (campanian), here are two very intriguing finds I could not classify at all. Does anybody know what they may represent?
  5. I was wondering if anyone ever made the claim to have the smallest articulated fossil, because I think I've got a decent shot! These are the smallest fish I've found so far. There are two Mioplosus labracoides and one Priscacara sp.
  6. Every facet of this specimen has me intrigued. Could this side contain fungi or flora? @JBkansas Potential Bryzoa? Ideas about the circles? Potential barnacle fragments below?

    Hadrosaurid shed tooth

    From the album: Aguja Formation

    A shed tooth from a juvenile Hadrosaurid. Their teeth are arranged in dental batteries which like a conveyer belt constantly replace worn teeth. Because these marvels of eating machinery house hundreds of teeth at a time, their worn teeth are fairly common. In addition to being worn by the animal's mastication, shed teeth are often smoothed and tumbled by rivers before they are buried in sediment and fossilized.
  8. ThePhysicist

    Hybodont tooth

    From the album: Aguja Formation

    A tooth from an ancient order of shark-like fishes. Their roots are rarely preserved.
  9. ThePhysicist

    Restesia tooth

    From the album: Aguja Formation

    Freshwater "carpet shark" tooth - they closely resemble those of extant "wobbegongs."
  10. ThePhysicist

    Baby Hadrosaurid shed tooth

    From the album: Aguja Formation

    Shed tooth from a very young "duckbill" dinosaur from West TX. Height: 4 mm.
  11. ThePhysicist

    Ray denticle

    From the album: Aguja Formation

    Orthacanthus teeth

    From the album: Permian

    Some more complete Orthacanthus teeth, each maybe about 1/4" in size
  13. ThePhysicist

    Handful of broken Orthacanthus

    From the album: Permian

    One of the most common fossils from the Permian (this locality in particular). Unfortunately, they are almost always broken. Of the hundreds of teeth I have, perhaps only a few larger than a couple of mm are mostly complete.

    Texas Permian micros

    From the album: Permian

    A handful of the more interesting (of very few) fossils I found in unprocessed matrix from the Archer City fm. here in TX.
  15. ThePhysicist

    Eryops tooth

    From the album: Permian

    Eryops teeth are conical (this one bears no carinae, though don't know if that's true for the whole dentition), and often have basal creases.
  16. ThePhysicist

    Permian micro display

    From the album: Permian

    It's remarkable how much of an ecosystem's diversity can be captured in a space smaller than a matchbox. In this case are the likes of Dimetrodon, Eryops, Archeria, Seymouria et al.
  17. ThePhysicist

    Actinopterygian fish teeth

    From the album: Permian

    Actinopterygian (ray-finned) fish teeth from the Early Permian of OK (Wellington Fm.).
  18. 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.
  19. 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.
  20. 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).
  21. 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"
