I love pseudofossils that look somewhat realistic and plausible, here are some that I'll be interpreting in a fake "paper" I'm writing to practice my scientific writing skills. They're probably just some iron stains but these are still some "imaginary segments" that could be distinguished.

Hi everyone this is matt again can anyone tell me what kind of trilobite this is I found today ? here is 2 photos

Howdy all, Had some great luck fossil hunting in the Drakes Formation today, particularly in this piece here. This is a chunk of matrix with several isotelus molt fragments and this particular one pictured here is the largest I've ever found. The reason I'm making this post is because of a structure I found on the underside of the piece. I at first took it for a brachiopod, but after cleaning it off and looking closer, I wasn't so sure. One surface of it looks like the typical grooves you'd see on brachiopod genera such as hebertella and rafinesquina, but looking over on another surface of the structure, it looks like typical isotelus remains, which confuses me. The structure also continues into the matrix in a very un-brachiopodish way. I'm curious if this could be a hypostome from an isotelus or some other structure from that genus, or if it could be from another arthropod entirely. I'm including a video to give a better view of all the angles. 20240714_022412~2.mp4

This was found in the Carboniferous limestone of the Malahide formation , east coast Dublin Ireland. I just wanted a second opinion on this one, i include a photo from Palaeozoic Fossils and figure 2 looks exactly like what I have. I would appreciate your input.

I would appreciate it if you could tell me about the Scotoharpes trilobite.
dongmin posted a topic in Questions & Answers
I would like to know about the species Scotoharpes spasskii, but there is very little information, so I have a question. Is this species completely different from the Harpes species found in Morocco that lived during the Devonian period? And is Scotoharpes spasskii a rare species of trilobite that is hard to find? Which is rarer among Russian trilobites: Paraceraurus or Scotoharpes spasskii?

Calling all lobster aficionados! I collected these lobsters from what I believe to be the baculites compressus zone/upper campanian Pierre shale in western South Dakota. I'm trying to get a specific ID for these fellas. I've read about Paleonephrops Browni and Linuparus Canadensis being found in my area, but neither really seems to fit with these. Please excuse my unfinished prep work on the double, it's still in progress.

Found in Pennsylvanian Aged Roadcut in Bethany, WV. The leaf is macroneuropteris I believe however the second fossil stumps me. Could it be some sort of terrestrial arthropod?

Hi . Any idea what this fossil is? Ordovician from Morocco.

is this bone ? It looks more like 2 arthropods I'm still cleaning it up

Howdy folks! I’ve had a lot going on so I haven’t been super active on here as of late, but I wanted to do a little recap of some of my favorite finds and acquisitions of 2023. Hope yall enjoy! Thanks for looking! First up is by far my favorite find from last year. This bug was collected as a ventral specimen in February, and was flipped and prepped dorsally by Jon Ginouves. Hypodicranotus striatulus is an exceptionally rare species from the Middle Ordovician Trenton Group of NY and equivalent strata in Canada. This is the first NY specimen I have ever seen or heard of coming out of strata outside of the Walcott-Rust Quarry. Up next is another piece from the same locality as the Hypodicranotus. I believe this came out of the site in the late spring or early summer. Generally, juvenile Gravicalymene magnotuberculata are near impossible to find, but I stumbled upon a mass plate containing around 20-25 specimens ranging from prone to fully enrolled. It is entirely possible that this is the largest cluster of this species ever collected, which is pretty sweet. This pic doesn’t show the whole plate, but you can get the general idea of how plentiful the trilobites are! This next specimen is just a cephalon, but it is from the iconic and very rare Walcott-Rust Quarry trilobite species Sphaerocoryphe robusta. This was found when I visited the locality in June with @KompsFossilsNMinerals . Normally I only focus on trilobites while collecting, but this past October I made a couple short visits to a Fiddlers Green Formation eurypterid site very close to my college campus. Eurypterid material is very sparse, but I did find some pretty interesting pieces. The most exciting of these was a partial Dolichopterus macrocheirus specimen showing the prosoma, 2 tergites and most of the appendages. Along with the usual trilobite suspects, I also ventured into some new territory strata-wise. I was able to visit an Onondaga Limestone locality several times during the summer and fall where I found half a dozen or so Odontocephalus selenurus specimens. Through my work in the Tully Limestone, I have become good friends with Steven Mize, who primarily collects the unit’s trilobite species. He invited me to come collect the Tully with him in July, which is when he gave me this beautiful enrolled specimen of an undescribed Basidechenella sp. While out collecting, Steve found this plate of 6-8 undescribed Asteropygine sp. , which he was kind enough to let me keep! During this past fall, I became very interested in the various Cambrian biotas of China. Here are a couple of Radiodont appendages I acquired. I believe the first one is Guanshancaris kunmingensis, and the second is Anomalocaris saron. This is my favorite trilobite I acquired from China. Although it is only a partial, this Redlichia mansuyi from the Guanshan biota exhibits one of its robust antennae!

Looking to see if anyone is able to identify this as an Anomalocaris appendage? Measures approximately 60mm Middle Cambrian Latham Shale Marble Mountains, CA, USA Thanks in advance!

I acquired this specimen from an amateur fossil collector acquaintance of mine so unfortunately, I don't know where it was found and when it dates to. It is roughly the size of a dollar coin.

First Post! - Californian Anomalocaris
Sarcopterygiianson posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello! This is my first post. I'm happy to meet you all! I currently have a very modest fossil collection, but have been keeping my eyes peeled for some specimens that I was really excited about. I came across this fossil, which I was considering adding to my collection. It is described as a 200g fossil of a 60mm Anomalocaris appendage next to a small brachiopod. It was found in the Latham Shale in the Marble Mountains of California, and it's indicated that finding these is a very uncommon occurrence. I was wondering if anyone here might have insight as to if it's real, fake, or restored in any way. Thanks!

This was in a box that was labeled trilobites from what was labeled Providence Mt in California. But to me does not look like a trilobite.

Some classmates and I found these materials resembling an arthropod with a potential matching trace while having a field day a few weeks back. Due to the strange preservation and limited material, we've been struggling to ID them. We believe this looks like a partial, segmented arthropod- but it doesn't have the typical higher-quality carbonized preservation. Does anyone have any ideas? Canajoharie River - Canajoharie NY.

I've been fascinated with Aegirocassis for a while now. The fact that a complex, giant filter feeder occured so many millions of years ago astonishes me. Its just such an alien animal. I've found little fragments of arthropod molts in the Drakes formation which belong to Isotelus. That got me wondering. What are the chances that instead of these all being from isotelus, that they're instead from another arthropod such as a eurypterid or ordovician radiodont. Another question I have is, does aegirocassis or a radiodont related to aegirocassis occur in any places other than morocco. The Drakes formation seems to have experienced a submarine landslide (don't quote me on this) and most to all of the fossils there are of creatures that were overtaken by said landslide. (Not entirely sure if this is true) But, what if there were such radiodonts like aegirocassis living in the Drakes formation but the only fossils we would find of them is molt fragments like the ones I've found that fell off of the animal and were buried in the sediment, instead of whole body fossils because they were able to escape this landslide. Though, I suppose the only way to confirm that such a radiodont lived in the Drakes would be to find an actual fossilized corpse of one. Really I just think this is a fun idea but it definitely would be cool if it is true.

Hello! I bought these Cambrian soft tissue fossils supposedly from Yunnan in china off of online auction site. I won them in a bid for suspiciously cheap. They seem real to me, but I’d be interested in confirmation of that. I’m also interested what you guys have to say as to what these are. Thanks! One is listed as Naraoia spinosa, the other, fainter one is listed as Vetulicola.
