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).-

Howdy folks! I’m back for some more identifications, again. Theres not a lot published on my area for tracks/Ichnofossils, so perhaps someone here has seen something or knows what some of these might be. All are Clear Fork Permian from Abilene, Texas. Potential Arthropod? Track, potential Laoporus? Really odd, could be from an animal or might be something else Another oddity. Water droplets? Tetrapods, potential Laoporus or other. Thank you all for any insight! There’s just nothing published about this specific site so it’s been really tricky for me to identify things.

In my continued studies of my local Permian areas, I came across information on a site that I hadn’t been previously aware of. I’m working on a paper describing the outcrops in the areas near to Taylor, Baylor and Archer counties, as well as some close outliers when I come across them. Information on this site Clear Fork (Permian) 298.9-251.902 mya Lots of siltstone at this specific site, which is why there are tracks present. All the fossils came from an area about 10 x 15 ft in an outcrop that has weathered away, there’s lots of siltstone surrounding but the fossils were very specific to one small area of this outcrop. Not entirely sure why this is the case yet, but I’m reading up on it. Lovely view of a pond from atop the hill several feet above the exposure. Looking back down the hill at the localized exposure. A small amount of limestone in the adjacent area. Some of the seed ferns on the ground prior to being picked up. Great spot for splitting the siltstone, the ferns were beautifully preserved in the layers. The haul after being gently cleaned, the siltstone doesn’t stand up well to water at all. Delrnotea Abbotii Seed Ferns I collected lots of examples, but these are some of my favorite. Plant Material There were some examples of layered plant material, perhaps just stems from the seed ferns lying on the ground and decomposing. This one has me stumped, it might be water droplets, but I’m not sure yet. Any information or identification is very welcome! Tetrapod tracks, potentially Laoporus? Other Ichnofossils, they appear to be tracks, and some of them might be arthropod. One looks to be amphibian. Getting lighting to show the tracks is pretty tricky since they wash out under bright light. Some sort of drag marks, very strange. Indeterminate, two toes are clearly visible at the bottom right. Probably not enough to identify. Again, I don’t think enough for ID on some of these. top right This one may not be a track, it lacks the impression that the others have, but it stood out a lot so I picked it up in case. Potential Amphibian tracks, one is smaller and is going the opposite direction of the larger. I’m new to tracks and ichnofossils in general so I could be completely wrong. Not fossils, but these pieces of siltstone were pretty interesting. The white coloration goes completely through the stone. No idea what could cause this. Thanks all!
