Hi all, i'm buying that trilobite but i'm not expert in cambrian morocco trilos. That one seem real with no restoration but i'm not sure. Also not sure about species. Can you help me? Thanks

I acquired this enigmatic creature a while back and just rediscovered it in storage. It was found in the Heilinpu Fm, Kunming, Yunnan Province, China (Lower Cambrian, same age as the Chengjiang fauna). I have seen a few similar creatures offered from the same locality from a few sellers. It has been alternately labeled as either a cnidarian or ctenophoran. However, I've looked through a few dozen papers about cnidarians/ctenaphorans from Chengjiang and have found no similar specimens. Has anyone seen these before?

Hey TFF Members! I was able to do something very different from the normal Florida fossil hunting the other day. On the way up to Michigan for my Mother's wedding I stopped in Northern GA to hunt for Trilobites! I was saying the age wrong throughout the video, I thought they were Devonian. But turns out they are actually Camrian... even better! Hope you can check out the video when you get a chance. I had an amazing time doing this!

Short visit (1-2 hours) to famous locality near Las Vegas. I wish we would do better home work because some interesting trace fossils were identified only after we watched the video recordings. Perhaps, our "movie" will help you not to miss them when you will visit this unique place. It was a family Christmas trip, by the way. Also, if you know the species, please help with ID.

Here are some color pencil sketches of some Paleozoic agnathans I drew many years ago (maybe 6 or 7 years ago). Time is scarce, but seeing these again I somehow feel inclined to start sketching some new concepts again Polybranchiaspis yunannensis (Galeaspida) Early Devonian Qujing, Yunnan, China Haikouella lanceolata (Agnatha, Haikouellidae) Early Cambrian Chengjiang, Yunnan, China Stensiopelta pustulosa (Cephalaspida) Early Devonian Ternopil, Ukraine Pteraspis (Pteraspiformes) Early Devonian Ternopil, Ukraine

Large morrocan trilobite, real?
John525 posted a topic in Is It Real? How to Recognize Fossil Fabrications
I recently bought this large trilobite fossil at a rock/fossil shop in Texas. After doing research I found that their are apparently Alot of fakes out there. The fossil itself has the same grainy mineral characteristics as the rock surrounding it when a flashlight is shined on it. The tiny sandy mineral deposits sparkle. I did a small bite test that an article I read suggested to do and it did not feel like resin. It was very gritty and the same texture as the rock that surrounds the fossil. Please help me if you can. Sorry it is only 1 picture. It wouldn't let me upload any more.

This is an incredibly rare and colorful Chinese trilobite, and the crown jewel of my collection.

Today, I decided to stop and see what @MeargleSchmeargl left behind at the Conasauga River trilobite location. I do like collecting at this Cambrian site. It is not a matter of finding trilobites, it is deciding which pieces you want to keep. I only spent about 1 hour there and did not collect any matrix, I just felt like splitting some pieces and finding a few trilobites. Nothing special was found and they we’re all Aphelaspis brachyphasis. As stated in @MeargleSchmeargl post, the River was low and the matrix was dry, thus making it very easy to split. I have only seen the River lower than today on one other occasion. When it is low, it is easier to maneuver and find a place to get comfortable. Here are my finds from today- this is the least amount of trilobites that I have found, but it because it was just a quick stop and I was taking my time. Here is my favorite find of the day- Here are some others-

I purchased this trilobite fossil a while back. It was sold as Yinites sp. from the Early Cambrian Hongjingshao formation in China. I tried to both verify the genus and close in a species, but have been unable to do so. All the references to Yinites that I could find were old (circa 1940’s), and therefore I wasn’t able to find any actual literature online. Does anyone have any ideas?

Many years ago I found this trilobite on Marble Mountain in California. It is roughly 1 cm across at it's narrowest and 2cm acrossat it's widest.. It is probably cambrian age without much detail preserved. I am unsure of what layer it came from exactly, as it was found loose as is. Any general ideas would be appreciated.

So I found this little dude sitting pretty as could be in a rock pile up in Grand Isle Vermont. I am new to fossils and haven't learned about all the critters in my area yet. I think it's head armor? The area is dated to the mid Cambrian and the matrix is black shale. You can even see one little flipper thing on the left. (don't laugh at me I'm new! lol) So what is it?

I was on a hike on top of a hill (about 700 feet in elevation) in Chino Hills (roughly 50 miles inland from the Southern California coast line) and I picked up a few loose sedimentary slabs and looked under them. I found this clear fossil of a seashell. I’m wondering how old it could be? What period was a sea covering Southern California and this high up from sea level?

Went out on a dig near Utah for Modocia typicalis with Gene Boardman one of the site managers at U-Dig. Gene is a really nice guy. He gifted the first trilobite of the day to me (I asked if he was sure and he said he had a few more). We split a lot of rock. A lot of work for a few beautiful bugs. Each image is captioned. Some are out of order. This is the great Gene Boardman. What I admire the most besides his genuine personality and big grin, is that he's a tenacious fossil digger. He kept reminding me to check every rock and to keep splitting it down as far as it would go. Here he has a thin slab of Marjum shale but he was able to find the first trilobite of the day with this fine split method. Really nice guy. The Marjum was not easy to split. It kept fracturing in multiple spots. The overburden was very brittle so we had to get down into the good, red layers. Here we are letting the rock "sweat" as Gene calls it. That means you set your chisels in the rock and let it naturally split and come back later to open up the bench. Lots of hard work. Gene helps run the U-Dig site and is known around the area for his enthusiasm for hunting trilobites and other fossils. The first Modocia typicalis was recovered 2.5 hrs. into the dig. It's small but complete and has some decent features. This is Gene's finest Modocia typicalus in his shop. He did an excellent preparation job. This big Modocia (over an inch) probably isn't a full specimen but has some great features. This smaller Modocia popped out of the same slab as the larger one. You can see it's impression on the left side. Another of Gene's Modocias. Gene gifted this M. typicalis after our days labors. Boy was I happy!

Gene gifted this Modocia to me. Although it's not complete it's a fine specimen with some excellent details. I did gift him a box of fossils from Ohio and Maryland so I'll count this as a trade. These trilobites are relatively rare to find intact and complete. Gene claims one is found every 8-10 hours in the Marjum. The Marjum is brittle and unforgiving. Care must be taken to preserve these specimens in the field.

Gene recovered this M. typicalis in excellent condition and gifted it to me while out in the field.
