Hot Trilobite Action

Trilobites available for purchase. I've never seen one loose and separate from the rock like that. What amazing beings.

Trilobites, by the way, are close relatives to Chelicerata, also in the Phylum Arthropoda. Both evolved during the Cambrian Period (540-500 million years ago), with trilobites showing up at the front end of that period, Chelicerates near the end. Heh. A mere 35 million years difference (!!).
