Legal places to find Trilobites or Ammonites in California?
kwic13 posted a topic in General Fossil Discussion
Hello! My first post here. I was just wondering if anyone knew of specific locals in order to find ammonites or trilobites in California? I found the website below somewhat useful, and have googled some of the locals on this area that have slightly pinpointed more specific areas, but I do know that sometimes fossils are only present on one part of one exposed cliff, and whatnot, and if I am going to go through the middle of nowhere, I don't want to not see fossils. http://www.fossilspot.com/STATES/CA.HTM Anyways, I haven't quite chosen my road trip route yet, but I will start in Calexico, CA and end in San Francisco, CA. I will likely go to the Chocolate Mountains, up to Blythe, CA, then across the Mojave to Bakersfield, CA (passing by the Trilobite Wilderness), then through the Carrizo Plains, and then up to Pinnacles NP, and then hopefully end up in San Francisco. If anyone knows a spot that isn't too inaccessible (I will have a 4WD), please let me know! Thank you. -
I am fortunate enough to have such a huge amount of Middle Devonian Givetian material that I thought it best to put the older Middle Devonian stage, the Eifelian, in its own thread. There are some spectacular fossils here as well though! I thought a good place to start would be in the Formosa Reef, which I believe is quite early Eifelian. This tabulate coral and stromatoporoid reef continues similar complexes found from the Middle Silurian, see my: https://www.thefossilforum.com/topic/84678-adams-silurian/page/3/ thread from page three onwards for details. All these Formosa Reef specimens come from a delightful gift from my good friend @Monica who is a tad busy with life at the moment but is fine and still thinking of the forum. This outcrop can be found on Route 12 near Formosa/Amherstburg, Bruce County, Ontario, Canada. This beautiful-looking specimen came to me with only a third of it revealed but I managed to get it this far after nine days of painful pin prepping. Monica found another one and posted it for ID here: https://www.thefossilforum.com/topic/105528-weird-circular-imprints-formosa-reef-lower-devonian/#comment-1172285 The specimen was identified by another Canny Canadian @Kane to be the little stromatoporoid sponge Syringostroma cylindricum. Hardly a reef-builder, but gorgeous nonetheless. It does have a little thickness to it, but not much. Beautiful! Pretty thin, actually. I love this Monica, thank you!

Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelgill (Skelghyll) in Cumbria, Northern England. It seems to be a tabulate coral, but I can't find any listed for this location, only mentions of small, rare, rugose corals. It has the star shaped corallites of a Heliolitidid, but seems to be tightly packed together like a Favositidid. A couple of species of Palaeofavosites seem to be close and are a bit star-shaped,, but anyone know any better? @TqB@piranha hmm who else? The coral bit, an external mold, is a maximum of 3.5 cm across and each corallite up to 2 mm.

On a trip with some friends to an exposure of middle Devonian strata recently we found some pretty unique Mahatango fauna. I thought I’d share one of the specimens here that I recently prepped for my good friend Gavin May! The specimen below is a complete for the most part prone example of a very rare trilobite, Basidechnella kayseri. It was prepped with a air scribe, I still have to do a bit of landscaping too.

I shared a few of the bigger things I found when asking questions. But thought I'd share some of the other finds. I have find a lot of little and mini trilobites thought was interesting. Smallest 1mm. #1 #2 #2(closer) #3 #4 #5 #6(smallest) #6(closer)

Hello, Found this cephalon in Lucas County Ohio. It looks pretty good, both eyes, etc. It would however be a significant prep job, gluing and coming in, then from the top), I would have to pay for. I'm thinking it is worth it as this seems rare. Please help me guage this. There is more of this lens to explore, so I may wait to see if I find a better specimen. Thanks

Okay so I found this specimen at the Taughannock Falls in Ithaca New York. I found it at the edge of the gorge which consists of shale, composed of slit and clay that fell onto lime mud and hardened into rock. I've done some research and it appears to be a Brittle star trace fossil formed by their arm grazing the sand floor. Although, these Brittle Star fish traces are known as "Pteridichnites biseriatus" and they have only been discovered so far in upper Devonian shales out in western and eastern Virginia. I'm not an expert but to my knowledge the Ithaca geological formation is Devonian and was slowly covered by sand. Is it possible that the Brittle Star fish once roamed in the ancient sea now known as "Taughannock falls" today? Because a research team is trying to find this specimen and they are wondering if anyone has discovered it. Edit: Im referring to the dotted trackway. check this link out for more information. http://www.wvgs.wvnet.edu/www/news/Pteridichnites.htm

I found this actually beautiful Erbenochile in a European auction house. However, I think all the little spines on the pleural lobes and cheek spines aren't real. What do you think about that?

Please help me to classify species of asaphida(maybe Nileidae?) trilobites plate
syl1219s posted a topic in Fossil ID
Hi! I wanna classify about this trilobites plate. It from morocco. I think It is maybe Nileidae? please help me to classify this trilobites genus and species! Size of trilobites is 3.5~6cm. -
I have a partial trilobite cephalon that I collected from the Waldron Shale spoils piles at Falls of the Ohio State Park. Since it is not directly from the quarry wall, there is some uncertainty in the stratigraphy, but it is likely Waldron or the overlying Louisville Ls. both of which are right near the border between Lower and Upper Silurian. Hopefully there is enough here to give a shot at an ID. The best I can do is say it could be Metopolichas breviceps but there appear to be some differences. Hopefully someone like @Kane or @piranha or @Ken K can see enough here to have an opinion. If not, "Trilobite Head" it will be called. Thanks for any help. Here it is enhanced a bit hopefully so you can see it better. You can see by the scale that it is under 1 cm wide. My stab at an ID initially came from Halls 1879 publication on the Waldron. Below I have my specimen between the figure out of Hall (on the right) and an example of one from the American Museum of Natural History website (left). The AMNH site says this specimen is the only known complete example which just adds to my doubt on the ID, but I have not found a more common, better match. And lastly, here is a zoom in of the cephalon to hopefully show the small bumps covering it. Thanks again for any help.

Hello to all. The Acastella trilobite from my own collection. Well preserved. I tried to get close-ups of the eyes and some small details. Place of discovery: outskirts of the city of Kamenets-Podolsky, Khmelnitsky region of Ukraine. It was not possible to determine the exact age (Silurian or Devonian). Have a nice day 1.mp4 3.mp4 4.mp4

Hi I got this Ceratarges recently. I think it is better match with Ceratarges aries than Ceratarges koumalii. (I got the information from "Van Viersen, Allart & Prescher, Harald. (2011). New species of the lichid trilobite Ceratarges from the Middle Devonian in Morocco. Geologica Belgica. 14. 193-202." ) what do you think about? Seller told me that it from Hamar Laghdad, Alnif.

So I got out of work early yesterday and headed off in hopes to find a few trilobites. I started off by finding a flexicalymene, and another. Then it happened! I found a fraction of an isotelus! I was stoked and ready to head home! On my way back to my vehicle I figured that I would look for more. I stopped and stared up the slope and out of the cornet of my eye I spot it staring out towards me! I quickly and carefully remove it from the ground, which made me even more stoked! Here are a few photos!

I found some interesting specimens as I was probing soft reddish colored Rock (sandstone?) that had been dumped in a field near my house Atchison Kansas. I could be wrong with my assumption is that it's from the nearby Missouri River. A handful of interesting observations pictured here but I'm not sure about. 1) The hard oozy substance on one rock. Is that amber? 2) the half dollar sized impression that looks like it's an Amber upon another rock. Could that be some kind of plant? 3) one rock has a thin black band across it. Wondering what ancient event might be known to cause that? 4) most interesting, I found a few Trilobite looking figures. From what I've dug into so far, looks like they might bea Carolina praying mantis oothecas. I have read that these can be hard, but they feel hard like the rock, or at least close to it. Nearby I did see s momome cotton-like material that look like it could be another stage of this creature. But then again it wasn't very thick and just a little bit of cotton material there. I have the suspicion that perhaps these were more ancient oothecas partially fossilized. But that was only a wild guess. Any insights into any of the above would be most welcome. Thanks for any help you can provide.

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.
