  1. So...... let's say I wanted to collect one specimen of each class of echinoderms (yes, the classes are always in flux, I know). Not a great specimen, just some ossicle or fragment easily determinable to be a member of that class for each class. It would be a fun trip around the world going to a set of localities, each of which was the easiest place in the world to find specimens of some particular echinoderm class. Some classes (crinoids, echinoids) seem almost too easy; others (blastoids, cyclocystoids, paracrinoids) are hard in some parts of the world but trivially easy here in eastern Missouri, USA. But more obscure classes of echinoderms (ctenocystoids, cinctans, solutans, stylophorans) seem to be hard to find no matter where you go; for each of these, I'm curious what formation / location would be the *least* hard. So let's start with a weird one: Where in the world is it *least difficult* to find a fossil readily determinable as belonging to an ophiocistioid?
  2. Hello all, I've been a fossil admirer for many years and finally pulled the trigger to get a few pieces of my own this week at the Denver show. Regrettably, I didn't do any research into fakes beforehand - didn't even cross my mind, as this is an organized and seemingly reputable event. I bought two trilobite fossils and one brittle star. Each was from a different vendor, all of whom were from Morocco. When I started doing some reading to try to confirm their species after I got home, I found many resources about fake fossils including this forum. I now suspect that all three of my fossils are fakes, as I can see what appear to be pinholes from resin bubbles on them. I've attached some photos. The larger trilobite I got from a guy who had tons of different-sized trilobites in various positions on different bits of stone, and it has visible cracks where it's been reassembled. However it seems to have clear pinholes across its head. The brittle star seems like the most obvious fake after learning more about fakes, given the color and shininess plus the couple of pinholes. I'm not really sure what to do at this point - I still admire these pieces and find them quite beautiful. If they're casts of real fossils they retain some of their interest for me. But it feels really bad to have been duped, potentially three times, in my first foray into fossil collecting. I have half a mind to go back and confront the vendors (I paid two of them with zelle and have their names and information) but I'm not sure what would be gained. Is there some way I could notify the venue so that other buyers don't get swindled? Curious to hear people's thoughts on whether these are indeed all fakes, and what you would do in my place. Currently I'm leaning towards considering it a lesson and keeping them as pieces of art, but the bad taste does linger. Thanks for your time!
  3. I am struggling to find proper information on how to identify different brittlestar genuses, so if anyone has a good resource for that, that would be great as well! Found at place de la Crevasse near Equihen, when splitting open a fallen block of layered, clayey shale. Scale is in cm.

  5. I was interested in purchasing this brittle starfish fossil from Morocco. I've read how there are a lot of fakes out there. I'd really appreciate some insight. Thanks!
