One of my fossil forum chums, Ron from Montana, shipped to me a big bug in a box. This thing makes all my other trilobites look puny!
He also threw in a sweet little ammonite with some opalescent lustre:
And here are some pictures of the big trilobite. It is from Morocco, and it looks like a Drotops megalomanicus. As there is a thriving cottage industry in Morocco in producing fakes, I've inspected this carefully. No resin bubbles, and these trilobites have some black calcite. It doesn't look like an restoration work was done on this one, and some of the prep was a bit rough. It is mostly covered with pustular little nodules, some of which seem to have been abraded off by a bit of sloppy preparation. Still, a very large trilobite at about 5 1/2 inches (12.5 cm).
