This Trilobite looks better than it has in 500,000,000 years -- thanks to careful preparation by Donald.

I asked Donald if he had some kind of professional experience. He said, "No ... He was just very careful."

Trilobites were a dominant life form for hundreds of millions of years on Earth. So there are a lot of places where they can be collected. This one came from the "West Desert" near Delta, Utah.
