Beautiful trilobite....Rana pipiens. When fossilized coiled it looks like a frog. Just beautiful. Devonian
Sure you are not talking about the Phacops Rana, Silica, Ohio (Devonian I believe)?
You have got to check out its eyelens. Scores of them are visible in a good specimen.
There are great Moroccan trilobites on the market that are very inexpensive. My kids got me an Ollenellus that is about 10 inches long for about $75 in Alexandria, Va.
I once wanted to buy a Moroccan ammonoid, but it cost hundreds, if not thousands of dollars, weighed about 300 pounds, and was the size of a squashed Volkswagen. It would not fit in my car or in my house. Oh the pity.
Elrathi kingi are kinda cute for little critters.
Good digging!
