Tracks? (Please forgive if this is the wrong thread, I'm new here!)
RockyLizard posted a topic in Fossil ID
Location: Central Oklahoma, SE Oklahoma county. We have Garber sandstone outcroppings on our property. We've lived here over a decade, and I never noticed these indentations until recently, when I stopped to clean up after my dog. I literally came back with a broom to clean them up so they were more visible 🤣 They remind me a lot of the prints my dogs make in snow, only it's in sandstone. I tried to get photos of the individual indentations, and the groupings/lines of them at well, but it's hard to see well unless you zoom. So could they be tracks? Or am I yet another case of pareidolia? 🤣 What else could make these regular, fairly evenly spaced indentations, in sandstone? I just want to know, even if the answer is, it's just my wishful thinking! I know we've had at least two prehistoric inundations of this area, but there are also terrestrial vertebrates here in central Oklahoma. And I don't know enough about it to have any idea one way or another. Very grateful in advance for any genuine, knowledgeable input! -

I found a new track area. Not great tracks but definitely tridactyl tracks! Chirothere and rotodactylus also so far. This must be Chinle Formation. The article on my trackway is due in January.

Been ill so wandering around my tracks and saw this today. I have pestered Spencer with a million “no those are chirothere undertracks” but this I really wonder about. Remember it’s Middle Triassic so three toed tracks are rare or nonexistent depending on who you ask. Let me know what you think. The track above the rule is rotodactylus

Hi everyone. I was up in northwest Pennsylvania a few days ago seeing some friends and found this wild thing on their property. It's not my usual hunting grounds and I wasn't particularly looking for fossils at the time, so I never bothered to do research on the area. What I can tell you is that it was found in northern Crawford County, PA, which I believe is Devonian (but may also be Mississippian). Nearby were some brachiopods in sandstone. If extra pictures are needed, just let me know. Please help!

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.

Found a new set of tracks recently. Still excavating and reassembling. Tracks are very deep so must be soft mud. Not super distinct. Much larger than the usual tracks.

Hello. I found this piece during my first visit to Mazon last year and just got around to asking about it. I believe it may be tracks of some sort, as they look vaguely like other arthropod ichnofossils. I was wondering if anyone may be able to confirm my suspicions and possibly ID what kind of animal it could be. I understand this second part is difficult without anything else to go off of, and I apologize for lower camera quality than the other images I’ve seen here. Thank you!

Ran across this rock at my neighbor’s property. These are most likely millipede tracks. It’s a big thick rock so getting it home will be a challenge.

Reptile Trace Fossils Stolen from Capitol Reef National Park
Crusty_Crab posted a topic in Fossil News
Reptile tracks dating from 251 MYA from the early Triassic were stolen around 2017/2018 from Capitol Reef National Park, but only recently noticed. Hopefully the perpetrators will be found and the fossils recovered. https://www.nps.gov/orgs/1563/care-rfi-05102022.htm -
Anyone have any Southeastern PA triassic track site localities
A.C. posted a topic in Questions & Answers
Hey all, I am really interested in finding some of the southeastern PA track fossils. I realize it is a huge stretch to ask for a locality but figure it is worth a shot to see if anyone wants to share information over PMs regarding locations or other useful information on this area. Thanks in advance!- 3 replies

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!

Permian Amphibian Tracks?
Rikache posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi everyone! First I want to say thank you to everyone who’s been so incredibly helpful these recent months. As my collection has started and slowly grown, I’ve always been able to depend on this forum for help, guidance, and knowledge. So thank you everyone! I recently came across this “Permian amphibious track” and it really caught my eye. Personally, the Permian period has always been one of my favorites and most interesting periods to learn about so I would love to be able to add something from that period to my collection, especially something this interesting. I was wondering if anyone could give me some insight on whether this specimen matches its description and whether you believe it’s legit. The tracks are said to be from Lodeve, France and are said to be from an animal that resembles todays salamander. Please let me know what y’all think! -
I recently received a few tracks from a friend and haven’t really shown them here. Enjoy Chirotherium barthii or Isochirotherium sp. Moenkopi Formation Holbrook Member Arizona 240 Million Years Old Middle Triassic These tracks were actually studied by Spencer Lucas and Hendrix Klein earlier this year. There also seems to be some plant material mixed in with the tracks in the larger slab in photo 4 as well, however I’m not to sure what species so I’ll probably post them in fossil ID later.

Hello folks. If anyone is looking for something semi interesting and maybe even fun to do at 1 PM.... in just 22 minutes, the Tate Geological Museum will be live streaming a fun talk on fossil footprints in honor of National Fossil Day. Trace fossils are the theme this year, so I will be showing off some of our pterosaur tracks. search for Tate Geological Museum on FB edit: and apparently available on the museum's FB page until forever.

So a few months ago I traveled to El Paso, in search of some trackways from dinos and Permian amphibians. My trackways collection has been lacking for the better part of my whole life so I decided to go get some. If you haven’t already seen them, I’ll include them here: Now how could I possibly get new footprints if I’m all the way in DC? Well, I was doing some cleaning with a toothbrush on this exact rock and to my amazement, I started seeing little footprints in the stone. Knowing that I didn’t see them before, I freaked out and almost had a heart attack. There are now 9 different sets of tracks on this one little plate! I’m in shock. Here’s some new pictures of the newly uncovered trackways!There are 5 additional tracks that I had no idea were there for over a month. I had this fossils for that period of time with no clue that there were more. Now that I think about it, there were probably a lot more back at the place where I chiseled them out. I didn’t look carefully enough, but I won’t make that same mistake next time. I hope you all enjoy these!

My husband purchased this landscaping rock in a pallet from a Bath/Bethlehem, PA area supplier about 20 years ago. Most of the supplier’s stones are from Pennsylvania. I’m guessing this is sandstone??? I’ve been staring at this rock for sometime and before I place it back, I wanted to get some opinions if anyone sees any type of tracks on this rock? I feel like my fingers fit in the specimen very nicely. Can’t tell if I’m seeing 3, 4 or 5 “toes” ? Maybe I’m just an imaginative newbie. Thanking anyone in advance who looks at these photos.

I found some more Permian tracks in New Mexico and I think they’re probably related to a Temnospondyl amphibian. I have the first track I found from this place here, but I also found one with 4 tracks in the rock that I’m fairly certain are some of the best I’ve found in a while. : Here are those tracks. Now something cool I noticed on this one is there is a track I circled here: because it pokes out on the other side, like this right here: I’ll also give you guys a close up of the other two in this rock that was initially exposed: That’s pretty much it for the tracks, but I figured showing them would be neat because they are my first and probably only ones I’ll be able to collect for a while. I’m overall happy with the way the trip to Texas went.

Wow is all I can say. I cannot believe what I have managed to find this week alone. I went to Texas for a vacation, and I’m coming out with some of my best fossils (in my opinion) I’ve found this year. I came here hoping to score some trace fossils of what once lived here, and score some, I did! Since there are two different time zones, and 4 different types of fossils found, I’ll split them up based on environment, and time. With marine fossils going first and tracks going second. Permian first, and Cretaceous second. I’ll do a picture of the whole haul and then we’ll get started. I also was able to capture some tracks that weren’t collectible so I collected them with my camera. Taking a fossil out of its place in a rock like that causes more damage than it does good, so all tracks were already eroded out and separated from anything scientific. Anyways, here’s the stuff: Permian Marine Fossils: Permian Footprint: while collecting today, I was hoping for a Permian footprint. Literally as I was about to leave, I found it! There was also another footprint attached to the rock but it fell off and scattered along the debris of similar colored rock. I wasn’t finding that anytime soon! But anyways, here it is. You can see a few sets of claw marks from the amphibian that once walked across it. I’m really happy I found this on a small rock and not one that I would have had to leave behind. cretaceous marine fossils: I also found a nice crab claw but it was so embedded into the rock that I just took a picture of it. Some things are better left to be appreciated by other people! cretaceous footprints: I found a bunch of footprints embedded into the rock, I of course didn’t attempt to take these out of their rightful place and I left them to be admired by others. I found one eroded out of the rock, and broken and incomplete, but it’s a footprint none the less. I’m pretty happy about all I found in general. It’s hard to see but the first two toes are there, and the only reason I’m confident this is a footprint is due to the fact that there were others around. All around a great trip and I still have more to find because I haven’t left yet!

Hello I found this piece of sandstone along the Athabasca river just south of Fort McMurray, Alberta, Canada. Since it’s sandstone I’m assuming it came from either the Mcmurray (late barremian or early Aptian) or Grandrapids (Albian) formation although my geology skills are not great. I tried to do some googling on what it could be but I found no results since I couldn’t be specific enough since I don’t really know what I’m doing. Any ideas? I attached an image of the location for fun that I took a while before I found the rock. I found it to the right of the creek thanks
