Just got this Russian trilobite in the mail. I haven't done any fossil prep before, but am really excited to get started. I tested the matrix with a pin and it feels fairly soft, I think a lot softer than the fossil. Right now I just have hand tools, but I do have an air abrasive machine coming in the mail. I haven't used one before though, so I don't want to start on this one. I do have an identical trilobite all prepped already, so it will serve as a good anatomical reference. My thought is to remove all the rock above the trilobite and use the longer side of matrix (left side in first pic) as a base (cutting it level to stand on). Not quite sure how to approach removing the large amount of rock. Once I get down to the trilobite I feel a little more confident.

Hello, I think these are a Cornuproetus plus a Reedops? Am I right? They are from Atchana. If yes, are the species known? Thanks in advance to you all. Miguel

Some time ago, my brother found this rock with a weird black blob on it. It was close to my home in Hamilton, NJ. The rock in most of the region is from the Cretaceous or Triassic, with the exeption of a tiny area of Cambrian rock. From left to right, it is almost exactly one inch. If it was a trilobite head, I guess the bottom side is the front and if it's a seashell, I guess that the upper part of the picture is the front/where the two valves meat. I will be very glad if you can identify this, whatever it is. Thank you!

Another Eldredgeops iowensis southworthi trilobite found at Arkona!
Shamalama posted a topic in Fossil Hunting Trips
Hey Guys, It's been a year since I was out fossil collecting because I was busy moving house. I finally got out to collect this past weekend and found the fossil of the trip on the first day. It's an enrolled Phacops Eldredgeops iowensis southworthi from the Hungry Hollow member of the Widder Formation from Hungry Hollow (Arkona), Ontario. I found it at the feet of our own @crinus as he was chatting with @middevonian. You can bet he was a tad jealous. @Malcolmt did a terrific job of cleaning the matrix off the piece to his exacting standards and the specimen looks gorgeous! He was also able to settle the argument that Crinus and Middevonian had over whether the pygidium was still in place. As found: After cleaning: A closer look at the glabella The left eye is mostly intact... ...but the right eye has been folded upon itself. Very happy to have found this. It is bigger than the one I found last year too!

Hi all I hope I do not wear out my welcome by keep posting so many questions . Found this years ago in a time before I got hooked on fossil collecting .I think it was in the Brecon Beacons . Is it is part of a trilobite.... or that is really what I was hoping. Thanks to everyone who posted on my last question really all enjoyed all your reposones . Bobby

Phacops, is this real?
Spinosaurus posted a topic in Is It Real? How to Recognize Fossil Fabrications
when i was surfing over the internet i found this beautifull phacops. but i don't know a lot about these things. so does anyone know if this is real. i saw this other trilobite, it's from the same seller, but the tail looks a bit fishy. thats why i just wanted to know if the other one is real too. this is the fishy one, the tail doesn't look right.

I found this in my usual rip rap spot, which has a maddening mix of formations (from Bois Blanc, Amherstburg, Dundee, and even some Hamilton Gp formations, too - yargh). My first instinct with this one was Anchiops anchiopsis, but there is something not quite right about this one. It is tough to make out if there is a pygidial spike for one, I cannot make out any incised axial rings, and it does not have the same acute angle of pleural tapering I usually see with this species. There appears to be a border on the lower left of the pygidium, and the pleura seem to stretch out quite widely while the axial part is quite thin (reminiscent of Coronura aspectans). Is this something else, or just another Anchiops that is simply freakish? I made a minor attempt to reveal more of it. Trilobites in this matrix do not preserve particularly well.

Trilobites are common in Northern Africa and prolific in Morocco but are scarce and very hard to find in the Middle East. Despite their rarity, extensive fieldtrips in Jordan to promissing localities proved worthwhile, we literally managed to find the first articulated trilobites in the Middle East in early mid Cambrian outcrops. Following is a link to the video I made documenting fieldtrips to the beautiful locality and some of the finds, enjoy.

I am hoping to add some trilobites to my fossil collection. I am especially looking for ones that look cartoonish for lack of a better word. Ones with big bulging eyes and the like, but I am open to all offers. Let me know if you have any and are willing to trade. -Matt

Brought my son fossil hunting today up in schoharie ny and he found something that sort of resembles a trilobite.

I obtained a rather attractive triobite today (my first one) but knowing that these fossils are often tampered with to some degree or another, I decided to put a little acetone on it to see if I could expose any restoration or remove any coatings that may have been applied (I want it for macro photography purposes, and coatings would ruin that). I covered it in acetone, left it for a few minutes, then rinsed it off. Now, instead of being jet black like it was originally, it looks silvery grey - like this: Of all the things I expected, it turning grey wasn't one of them. I thought black or brown were the natural colours. I don't really think the whole trilobite can be a fake, because for one thing it's too flawed, and for another the eyes have the tiny, tiny lenses. Have I just impacted upon a coating without removing it, or what? Any suggestions welcome!

Hello All, I’ve acquired some specimens of the species Ductina vietnamica, a blind phacopid trilobite from the Devonian of China and Vietnam. These specimens, dating to the Eifelian age of China, are fairly well preserved for the often-flattened and disarticulated type. Ductina was a rather successful phacopid, being recorded throughout most of the Devonian. They are small (my examples range between 1/2 an inch to 1.2 inches), with a simple effaced pygidum and a cephalon lacking many features (such as tubercles) found in its fellow trilobites of the Family Phacopidae. Most noticeably, Ductina is blind. Blindness is a trend in several groups of trilobites, but was also present in the relatives of the well-known Eldredgeops. This secondary blindness has often been interpreted as relating to the environmental conditions that the benthic trilobites faced (Clarkson, 1967). Taxonomy: Class: Trilobita Order: Phacopida Suborder: Phacopina Superfamily: Phacopoidea Family: Phacopidae Genus: Ductina Species: D. vietnamica Location Information: Country: China Province: Guangxi Formation: Unknown Here are some photos showing the details: A photo of the most complete specimen. There is some damage on the fragile pleurae, but for the most part, it is complete. This one is about 3/4 of an inch long. Close-up of the glabella and thorax of a red example. This one shows glabellar furrows that are absent in many examples. The pleurae are also in good shape. Citations: Clarkson, Euan. (1967).

I picked this up for a few quid in a Spanish market from a Moroccan dealer, who usually sells good stuff, but I'm fairly certain it's a fake, it was too cheap, the colour's not quite right and i would say some of it has been carved and painted. It has a couple of bits of real Cambrian trilobite on the back and seems to have a bit of a Flexicalymene or the like glued on top to provide authenticity. What do you guys think?

Does anyone have a suggestion of where to get tips for the end of sandblasting pencils? I have a two pencil unit with a blast box and the tanks on the back ( a vaniman sandstorm). Not sure either if there are different sizes with one more ideal than another? Will mostly be prepping trilobites and some fish.

Fiddling while Rome Burns, OR Fossil hunting while my home blows down
dalmayshun posted a topic in Fossil Hunting Trips
Well, my wife wanted to attend her college reunion in Wisconsin. She was scheduled to fly out of ft Myers Sunday am, but with the hurricane scheduled for the same time, I suggested we travel to Atlanta, evacuating, and allow her to catch a plane from there. That being accomplished, I found myself with at least three days to hang around Atlanta. I remember reading about Tibbs Bridge and so decided to check it out. what a beautiful place, and if you like trilobites, this place has one in practically every piece of muds stone. There are 6 - 8 different kinds of trilobites here. Many pieces, but some nice impressions also. I did find a pygidium and thorax molt that was intact and loose in its little impression niche, but the muds tone broke in half. I felt guilty having such a good time while Irma was assailing my home town, but it was a way to keep my mind off the possibilities... However horrific. The good news is my house is intact, guess those hurricane windows were a good investment. Please keep our area and all of Irma and Harvey's victims in your thoughts... And contribute if you can. I'm am adding an image of one of my favorite finds from this trip. Don't know what it is yet, I'll have to do some research when I get home.

Drotops Megalomanicus found it mislabeled and under priced at the mall today at a random booth, was a very unexpected pleasure measures somewhere around 5.3-5.4 inches, the condition is not to bad.

From the album: WhodamanHD's Fossil collection.
Bought before I knew much about trilobites (not that I know a great deal now) in a peculiar place in the New Mexican desert. I bought it for twice as much as I should have. I know very little about this specimen. It might be a flexicalymene. -
Trilobite Crotalocephalus real?
Seguidora-de-Isis posted a topic in Is It Real? How to Recognize Fossil Fabrications
Good afternoon to all! Is this Trilobite Crotalocephalus Gibbus really real? From which part of Morocco is it discovered? What would be the Period, Era, and Millions of years?

Hello Fossil Forum! First time post but been a reader for a while now. I just got back from my honeymoon in Morocco and of course along the way stopped in Erfoud to look at fossils. We went specifically to Macro Fossiles Kasbah where they had a huge selection of fossils and fossils-turned-into-home-goods (sinks, table-tops, etc.). There were huge sheets of fossils, a cutting and polishing area, etc. It seemed legit and I was walking around with the owner for an hour, Raffa, whose dad had owned the place since the 70s. He was very enthusiastic when I showed interest and had a (very rough compared to this forum) knowledge of what we were looking at. At any rate, I picked up two pieces that I would love your opinions on. Both from a specific-identification perspective and a quality / validity perspective. Obviously we have one trilobite and one crinoid. From my eyes I can tell the Crinoid is a composite of what seems to be a few pieces with a bit of filler in there. Not ideal but I love that it's one animal in focus for a smaller piece like this. The stone you see is 14" tall. The spiny trilobite he kept in his office and only showed me after a longer conversation. I believe it to be real and a fairly good example considering its age. The stone you see is 10" tall. Would love opinions on specific species and thoughts on the prep quality. Plan on mounting these vertically in custom frames for a larger specimen wall and hope I made a couple wise purchases! Thanks in advance for your thoughts.

Is this dual triobite fossil composite?
Golem posted a topic in Is It Real? How to Recognize Fossil Fabrications
This specimen caught my eye and I was wondering if the two trilobite were put together artificially? My second question is about the black color on these trilobites. I am not sure if they have shoe polish coating over them or the black color occurred naturally? I am still waiting for the seller to send me better close up pictures on the eye of Paralejurus, although it has nothing to do with the topic I will update the pictures when I get them. Of course any additional assessments on the fossil are greatly appreciated.

Here's one of the head shields from the same location , which I don't think has any relation to the previously posted spiny pygidium ... This is the only type of cephalon I've recovered from that spot.
