Hello all, after some trades with an associate of mine, I have a really nice trilobite in need of preparation. My experience mainly lies with crinoids and brachiopods, and I have only prepped a handful of trilobites. I'm not well familiar with the species anatomy or the rock type, so I would rather a more experienced trilo preparator try for the best quality results. The split rock is clean, and will glue back to prep out nicely it appears. It looks complete, with the split revealing an eye, some of the cephalon, legs, and pygidium. Just a bit of the genal spine remains in the opposite side of the rock. It looks like a nice Gerastos trilobite, probably Gerastos dhondtae of Eifelian (Jemelle Formation). I have more photos I can share, but will only put a few on here. Of course I'm willing to pay the postage and preparator their prepping fee for the service. If anyone knows any service, recommendations, or feels like maybe they are up to the challenge please post or PM me! Thanks, Jackson
nivek1969 posted a topic in Fossil IDHello all- I recently acquired another "fossil" from a guy that lives in Texas who supposedly bought this piece from a reputable dealer who claimed to have done all the work on it. This is my first time collecting trilobites, and I know that so many fakes come out of Morocco. I have read the sites about how to identify the fakes, and this piece has a couple of "red flags" but if it is a fake it's very well done, and even worth what I paid simply for being a piece of "art." I can see the shiny glued areas on the phacops, and some strange coloration changes. Like I said in posts before, I am a novice, especially with trilobites, and just doing research I thought it was odd these two varieties are on the same matrix and the smaller Gerastos is darker than the Phacops. The matrix is lighter than it probably should be, but I cannot see any bubble marks on it or the specimens which would indicate resin. I've also done the "tooth test" as well as examined the piece under UV light and both seem to indicate it is not a cast. Then again, people are getting much more clever these days with the fakes. The seller said I could have it checked out and return it if I wish within 30 days. Even if it is a fake piece, or that they are real, and the Gerastos was just added to the matrix, I"ll probably keep it. Please let me know what you think. Thanks! Here is more info. Phacops and a Gerastos on the same piece of matrix. Great preservation and preparation. Facets all visible on the Phacops and the Gerastos' head is near perfect. A few chips on the Phacops but nothing major or distracting. The Gerastos has some chips on the center lobe as shown in photos. Phacops is about 5 cm (2 inches) long. Devonian from the Mt. Issoumour area in Morocco. Piece is nicely prepped and needs no stand to display.
