Location: n-e Italy. Probably Permian or Carboniferous. It's a fossil? Algae?

Hello, Just purchased some Permian matrix bags from Richards Spur, OK and the Texas Red Beds. I have a few items I'm wondering if anyone can help me ID. I do have some guesses for a few of them. Using a dime for scale. Red Beds Going to guess Eryops skull fragment on this one. I think these might be fragments of Orthacanthus spines. Partial vert? This one is so small I really can't capture any distinct detail in the photo. Most small teeth fragments in this matrix were the broken tips of Orthacanthus teeth. However this is much rounder (although I can make out at least one edge), has no serration as far as I can tell, and under a very bright light I can see extremely fine vertical ridges (striae?) down the length of the tooth. It is also colored differently. Not hoping for much on this guy but my best guess would be some sort of amphibian. This one I'm fairly confident is an Archeria "jaw"; I understand they would have had some kind of palate plate to help grasp/swallow prey? More info on that would be awesome. It definitely matches what I've seen on Google. Richards Spur, OK Am very interested in this one in particular. Some kind of rooted tooth, it has this strange acorn shape to it. Not seen anything like it elsewhere. Thanks for having a look and my apologies for the poor photos; all I've got is a magnifying glass. I think I need to buy a book so I can try and identify this stuff on my own!

Identification: This tooth was found in processed microfossil matrix from Waurika, OK, USA. Reptile remains in general are very uncommon, so if you think you've found many pieces of Dimetrodon teeth, you're likely mistaking many Orthacanth shark cusps. Orthacanth shark enamel is smooth, and the serrations are quite prominent compared to those on Dimetrodon which are finer. Dimetrodon enamel is not smooth, as seen on this one. Dimetrodon crowns are also broader. Shark cusps broken at the foot of the crown also flare out, where reptile teeth do not. Were this crown complete, you would also notice a conical/round depression in the base. This is unlikely to be from another Sphenacodontid based on the locality, presence of serrations, and enamel ornamentation. https://www.nature.com/articles/ncomms4269 Notes: This tooth is a post-canine/posterior tooth, which is the tooth position one is more likely to find in micromatrix since they are smaller.

Greetings, I’ve recently gotten back into prospecting fossils and I’m looking for some suggestions on sites to visit in western Pennsylvania. I frequently visit Ambridge PA to find fern and Calamite fossils from the Mahoning fm and would like to find more. I also would like to find fossils of early Permian (tetrapods, plants, or invertebrates). I hear that Washington county (south of Pittsburgh) has some great spots and would like to know if it were true. I also would like to show some of my findings from Ambridge as well. Note: I’d like this to be suggested places not just western PA but West Virginia and eastern Ohio as well.

While my prime focus is essentially learning how to accurately describe Nature in the precise language of mathematics, I've always been intrigued by natural history - it's actually what started me on the path to physics. The sort of interrogation that paleontology practices provoked me to think and question even further, down to the fundamental science which makes it all work. Collecting fossils has brought a large amount of enjoyment to my life, and is often a welcome distraction from what can sometimes be straining work. The knowledge that I accumulate along the way is also part of the fun. Here is my collection, which will always be a work-in-progress. There's still many things I haven't photographed yet, but I feel comfortable saying this is the majority. I don't have many big things, but I'm certainly pleased with the many small things I have so far. Links to albums: Dinosaurs Sharks North Sulphur River Post Oak Creek Permian Aguja Formation Harding Sandstone Devonian Galveston Fossils Miscellaneous Highlights / Personal Favorites: The ones underlined are linked to their respective fossil page in the Fossil Forum Collections, which has more information and photos. Infant Tyrannosaurus rex posterior tooth If I could keep only one fossil, it would be this one. It's from my favorite animal that has ever lived, and being from a young'un is just so darn cool. A true crowning jewel in my eyes. Juvenile Tyrannosaurus rex maxillary tooth Again, you can't go wrong with T. rex. It doesn't have the best preservation but regardless, there's a lot more to love. Tylosaurus proriger tooth (self-found) Undoubtedly my favorite find to-date. Finding fossils yourself adds that extra value to its place in your collection. I'll remember the moment I first saw it for a long time. Triceratops prorsus tooth Triceratops is another one of my favorite dinosaurs, I think we all grew up playing with toys of T. rex and Triceratops. Unique circumstances also allow for me to say it's Triceratops and not Torosaurus with some confidence. It's not perfect, but still a significant part of the collection. Avisaurus archibaldi tooth A bird tooth? Doesn't get much cooler or more uncommon. Dimetrodon cf. limbatus tooth I've always been drawn to "icons of life," since those are the ones we remember from childhood. Dimetrodon is definitely an icon, and I'm glad to have found one of these uncommon treasures (in micromatrix - it was a very nice surprise). Cretoxyrhina mantelli tooth One of my favorite shark species, the "ginsu" had sleek-looking teeth, ate mosasaurs and dinosaurs, and was overall a formidable animal worthy of admiration. Cretodus crassidens tooth (self-found) Another one of my favorite sharks. It's not big or complete, but the preservation is so rare for the locality (POC) - the gloss on the enamel is as if it fell out of the shark's mouth yesterday. Saurornitholestes langstoni tooth I'm currently working on growing the dinosaur component of my collection, and this is my first Dromaeosaurid. Dromaeosaur tooth (Hell Creek Fm.) My most recent addition (as of Sept. 4, 2021), and it's my best dinosaur tooth for sure. Unfortunately it will be labeled as only a Dromaeosaurid tooth for now, but it still is just a great tooth from a cool family of dinosaurs. Shark Tooth Riker Display I've got one riker that I've tried to squeeze as many teeth into as possible. I need to get a couple more, probably; there's a lot of teeth that deserve a riker, but are just lying around. I'll try to update this thread semi-regularly as I make acquisitions in the future.

Ornamented lungfish bone/scales are fairly common, but their teeth seem to be comparatively rare. This one is ~ 3 mm in its longest dimension. ^Mottequin et al. (2015) -

Now how can this crumb of a tooth be attributed to Dimetrodon?? First, it's serrated. It could be shark? The enamel is not smooth (not very visible in this image, a little at the bottom), so no (additionally, the serration shape is different from those of Orthacanth sharks). That narrows it down to serrated Synapsids. It turns out that very few animals at this time and location had "true" serrations, not just enamel serrations, but bumps in the dentine beneath the enamel. The enamel on this piece happens to still be clear, allowing one to see the globular dentine underneath! From Brink and Reisz (2014), I'd posit that D. grandis is a suitable candidate. I'm also not an expert, so I welcome contrarian arguments. I highly doubt it's Therapsid, as I haven't heard of any from the Waurika locality. D. grandis:-

From the album: Permian
Dimetrodon sp. Wellington/Ryan Fm., Waurika, OK, USA Post-canine/posterior tooth This tooth is likely from D. limbatus, given the locality and presence of serrations: https://www.nature.com/articles/ncomms4269 The same paper also rules out other serrated Sphenacodonts by the enamel ornamentation. Its smaller size could indicate that it's from a juvenile. It differs from the comparatively abundant broken Orthacanth shark tooth cusps in the microfossil matrix (what most people are likely to confuse with): the enamel texture is not smooth, the crown is very broad (indicating it's likely a posterior, in addition to its size), it has fine serrations that differ in shape from the sharks', and the base doesn't flare out. Were this crown complete, you'd also notice a conical/rounded depression in the base. A beautiful tooth from one of our surprisingly close cousins. -
Hi y'all. Found this in some Permian micromatrix from Waurika, OK. There's no way I'm this lucky, but is this a very tiny Dimetrodon claw? I've tried to get access to this paper, but still waiting to see if the authors will send the text. I'm fairly confident it's at least sphenacodontid, based on pictures I've seen on the forum. It's about 3 mm in length. @dinodigger@jdp

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!

Hello everyone, I recently got some fossils from Russia, some plant remains from Perm Krai where I grew up and a couple of Productid brachiopods from Sverdlovsk Oblast. They are from the Artinskian stage of the Permian period, one is around 2.5cm in width while the other even though incomplete is absolutely gigantic, the largest I have in my collection. I am not great at identifying Productid brachiopods and the Permian is probably the period I have least experience with within the Paleozoic so I have not been able to ID them myself. The large one looks similar to some Reticulatia sp. I've seen online but all of those are smaller so I don't know if that's accurate, the smaller one I have no idea. Thank you for any help, Misha

Hello. From a recent trip to the Perm-Carboniferous petrified wood, we brought back some very interesting fragments; nothing like this has come across before. Usually we find fragments of wood (chips), without knots, without a pronounced structure - just highly silicified, indeterminate fragments. But while this trip from a small area (just a couple of square meters), we collected several interesting fragments. This is a solid piece of the trunk with knots located at the same level. 7 knots. Another similar fragment, but split lengthwise. There are only 3 knots left, but a cavity with smoky quartz crystals has opened. I want to identify these findings. Having looked at the photographs and drawings, which depict Araucaria, I saw that the branches of this tree are arranged in "layers", i.e. on the same level. Why did I take Araucaria as a basis - in some literature, local layers are called Araucarian. I would be glad to receive any information. By the way, I have a similar trunk with knots on the same level - but it is from the Paleogene; much better preserved, replaced by chalcedony, and has 5 knots.

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!

These are virtually all the microfossils I found in two small bags of medium-grain matrix from Waurika, OK. The matrix was very fossil rich. The vast majority of the fossils are Xenacanth/Orthacanth shark teeth. Fish material is next most common, then amphibian, and lastly, identifiable reptile material is very rare. -
I found this a few years back near (but not in) Guadalupe Mts National Park. Is it a sponge, coral, algae, or something else? Piece is about 6 inches across. Thank you for your help.
