Hello, friends! I am currently sorting through my Devonian trilobites from that rather wonderful country - Morocco! Now I picked this first one up from a shop that had a whole table covered in the same species, and boxes underneath. The proprietor only knew they were from south west Morocco, but I was fairly certain from my accrued knowledge that they were "Izi", the Amazigh (language of the indigenous Berber people) for flies as they are so numerous at some localities. This is thus likely to be Gerastos tuberculatus marocensis, and since they were cheap as chips and I haggled, I left with this one in my greedy paws. Not perfect, but nice enough as an example of the species. It's a very small bug and i've only done a teensy bit of my own prepping on it so far. At a junk shop in Fes, I found a box with about twenty poorly prepped trilobites that again I was able t purchase at very little cost, just a few dollars each. These look like they've been used for trainees to practice their prepping and then discarded. Common enough species, but with a bit of fiddling they can end up looking reasonable. One of the specimens seems to be Gerastos, but it's a lot bigger than the first one and the dimensions look a little different. Is it the same species but with regional or chronological variation? The little one is probably Upper Emsian, are the Eifelian examples bigger? Is it another species of Gerastos from the Middle Devonian? Or another proetid genus? Just that I have a small one and a big one? I would be interested in anyone's thoughts on this, please. I have done a moderate amount of pin prep on the larger specimen, but it's hard work and I'd like to know if it's worth continuing. Here are some of the other trilobites from the box where the bigger one was found. Looks like the same matrix and prepping style to me, different coloured rock to the first specimen. Haven't prepped or formally identified these yet, but maybe Hollardops, Coltraneia, and something akin to Cornuproetus? Possibly from the same locality, maybe not or if so maybe different levels? No way of knowing. Thank you to all who take a look and double thanks for any helpful comments. @piranha@Kane

Hi all! Just wanted to share my little collection of trilobites and pals now that I have a small assortment. I hope you enjoy! I’m working up to actually getting out in the field soon, so hopefully a few finds of my own might join these fellers!

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
