PalaeoArt Posted July 22, 2017 Share Posted July 22, 2017 I recently purchased a 6x5" piece of shale from an auction of an old geological/fossil collection. This contained 5 trilobites of the same species but no info on where it came from. It wasn't much money, but would love some assistance in trying to ID the species. I've no idea of the location or age sadly as there was literally no info that came with it (although I purchased a few other North American trilobites in the same auction). The 5 trilobites range in size from 1" to 1.5". Thanks in advance. Link to comment Share on other sites More sharing options...

sTamprockcoin Posted July 23, 2017 Share Posted July 23, 2017 reminds me of bad quote about a blind squirrel - just had to get that of my mind! “Beautiful is what we see.
