    Curious find from the Culpeper Basin

    I recently returned to hunt at my local Culpeper Basin creek site, and although the hunt was not incredibly fruitful, I did run across an interesting specimen. I have walked by this particular oddity many times and did post an image of it in my original trip report, but I remain very curious as to what this might be - if it is anything at all. To add some background information, I believe that the majority of the rocks exposed fall within the Balls Bluff Siltstone member of the Passaic Formation. All fossils that have been recovered thus far from the locality have been plant fossils, which may increase the likelihood that the specimen has a floral origin if it is a fossil at all. Here are a few different photographs of the specimen in question: I apologize if some of the photographs are not the clearest; unfortunately my phone camera tends to make the images noticeably less focused when I zoom in. Unfortunately, I forgot the specimen at the site when I left , but if more photographs are needed I would be happy to fetch it, scrub off the algae and dirt, and upload better photos to this topic. Hopefully it is possible to determine what this is, but it may be somewhat difficult since it seems quite water-worn like many of the rocks present at this particular locality. @cck, @Fossildude19, have either of you seen something like this elsewhere in the Culpeper Basin or elsewhere in the Passaic Formation? Thank you in advance to those who comment on this post.

    Culpeper Basin Possible Track

    Location: Loudoun County, VA (near Ashburn) Formation: Newark Supergroup —> Culpeper Basin Background: Okay! Here we go. Another track. I will preface this by saying that I don’t know if it’s Grallator, or very well may not be (or not a track at all). Here is how I found it in the field: I picked it up after seeing the middle toe. I didn’t really think much of it, except that it had a rough knuckle-y shape like my other print. Then, I noticed the roughly-three-toed shape. But I was only sold on it when I noticed the rightmost toe, and how pronounced it is. It really sharply but smoothly tapers off into a “claw”. Next, a shot in the sun with the ruler on my multi tool, and a closeup of the claw: The photos don’t do this toe justice to how prominently it is formed in the rock. Here are some low-angle lighting shots: And lastly, a brightened photo and the same photo with an outline of what I am looking at: Thanks for taking a look! At the end of the day, photo-ID of tracks are difficult so I will end up taking this along to Dr. Weems when I go to pick up my old track. But I will appreciate everyone’s insight regardless.

    Newark Supergroup Tracks

    Hello all, I was wondering if anyone has had experience with tracks (specifically dinosaur, preferably grallator?) in red sandstone/mudstone. I recently turned my attention to the various types of red sedimentary rocks in the Triassic Culpeper Basin of VA because of successes I had many years ago looking for worm burrow traces in a group expedition. I was stopping off at construction sites near Ashburn and poking around for burrows or other small trace fossils and I unexpectedly found what appears to be a full blown Grallator track. I have to clean it and take proper photos before I make an ID post but I thought I’d ask about the possibility of this happening in redstones before getting my hopes shattered . It is very subtle and I wouldn’t have bothered picking it up if I didn’t spot a seemingly very obvious right toe and then the rest of the shape. In any case, I’m meeting with Dr. Rob Weems to pick up my old Cretaceous print so I will bring this along.

    Culpeper Basin Unknown

    Hello all, Quick backstory on this: I’ve been researching the Triassic Culpeper Basin of VA for a little while now. I’ve been paying more attention to various formations I see when I’m around northern VA especially after reading more about the stratigraphy of the area from old papers. I’ve taken a special interest in this red mudstone (or is it siltstone or sandstone? I don’t know the exact difference to be honest) because it’s what I’m familiar with. I participated in this program as a kid with Dr. Peter Kranz where he took us all over the DC area during a week in the summer and one spot was at a construction site in Manassas, where we looked for worm burrow ichnofossils. Talked recently with @Andúril Flame of the West about this. I had a couple small specimens from that trip with what I assumed to be the burrows/other traces so I knew roughly what rock type and structure to look for. And there’s plenty of this red rock all over NOVA. So I figured I would look at whatever red rocks I see just in case it would have something. Today I visited family in Ashburn VA and looked at some of these red mudstone-like rocks in their garden. They had gotten them from spoil piles when the community was under development to add to their garden decor. I saw sedimentary structures on many of the rocks, but this was the most clear one with something interesting going on. Just thought I’d post in case someone has insights on what it may be. Thanks! Specifically, it’s the three-pointed marking on the rock. Is it a burrow trace, or maybe drag lines? It’s not a fracture or some other damage to the surface, the consistency of the rock surface changes and is almost like the soil was disturbed over that line and hardened as-is. apologies for lack of scale, didn’t have access to tools at the time and don’t have the specimen in my possession. (Ashburn VA, Culpeper Basin-Newark Supergroup)

    Culpeper Basin Plant Fossil?

    Early last month I made a post regarding a specimen that I had recovered from the Newark Supergroup that I had thought could be a possible trace fossil. After discussing the find on the forum and contacting some experts on Newark material, it was determined that the specimen was in fact not a fossil. However, this find greatly increased my interest in the fossil content of the Culpeper Basin. Today I decided to visit one of my favorite streams with the intent of fishing - but I could not help checking out some exposed rocks, knowing well that the stream would cut through Newark strata. As a point of reference, I have included a map of the component formations of the Culpeper Basin that occur in northern Virginia. The red circle is approximately where the specimen in question was found, so it could have come from either the Bull Run Formation or the Manassas Sandstone. Weems, R. E., Culp, M. J., & Wings, O. (2007). Evidence for Prosauropod Dinosaur Gastroliths in the Bull Run Formation (Upper Triassic, Norian) of Virginia. Ichnos, 14(3-4), pp. 271-295. https://doi.org/10.1080/10420940601050030. When checking out the rocks I was simply hoping to learn something about the exposed strata that might indicate the formation present. However, I came across the intriguing specimen pictured below. I have not heard of any fossils coming from this particular area, so I am not sure whether the fossil is what it appears to be or whether it is something entirely different. A view of the entire specimen with the suspected carbonized plant material at the top end. I apologize for the poor picture quality. If better photographs are needed for identification, I would be more than happy to provide some in natural light. A closer image of what may be fossilized plant material. I believe that plant material has been recovered from the Bull Run Formation (where this specimen likely originated) so it could very well be a plant imprint. I know nothing of botanical terminology, but the horizontal lines across the specimen appear to be consistent with what might be expected from carbonized plant remains. It should also be noted that the specimen was found as a loose clast, though it was found among an abundance of very similar material. Hopefully this last photograph provides the necessary detail to properly evaluate the specimen. Again, if more photographs are needed be sure to let me know. Thanks in advance to everyone who comments on this post . @cck @EMP @Fossildude19

    Possible Trace Fossil

    Hello all, A few months back I happened upon an intriguing rock while taking a walk in the woods. The main groove on the front of the rock struck me as a possible trace fossil (perhaps a worm burrow or a tunnel created by plant roots). I considered the possibility that it could potentially be a fossil since it was found in the Newark Supergroup of northern Virginia which is know to have some fossiliferous rocks. However, I fully expect that it is simply an artifact of weathering or that it has a geologic origin. Can any confirm whether it is a trace fossil or simply a case of weathering? I’ll tag a few members that I feel are knowledgeable on this subject: @Fossildude19 @EMP @cck @WhodamanHD I deeply appreciate all input.

  15. Made another trip to the Triassic Cumnock formation of North Carolina. Split a LOT of shale, got what I believe are 3 nice plant fossils!!! (6 total since they split) One looks like a compression fossil of ginkgo leaves I think..the other 2 I think are plant vasculature. Can someone confirm this? I want to make sure these are actual fossils too, not pseudofossils... Also, I found some nodules as a part of one of the plant stems with odd bluish yellow minerals..not sure what that is. Thanks everyone!!
  16. So I just made a trip to a publicly accessible creek that cuts through the Triassic Cumnock formation of North Carolina. Made a couple of nice finds. An unknown plant fossil, it’s worn down a bit, but anyone think they can ID? Also found a TON of what I believe are Cyzicus fossils, the largest are just shy of 1cm. Can anyone confirm these are Cyzicus? Thanks for the help!!!

  21. Here is a picture of a Bivalve imprint I found whilst in a Creek in Western Wake County. I was in the Triassic Basin and they have fossils dating back around 230 Ma ± 2 ma. It was part of the Carnian Stage of the Triassic part of the bigger Newark Supergroup. I presume it is a freshwater genus but I don't hear much about freshwater Bivalves when it comes to Triassic fossils.
