You are not supposed to find good fossils close to a plutonic intrusion…but these trilobites are the exception!
A nice specimen of Pseudatops reticulatus from the Early Cambrian of Totanés, Toledo.

Maybe looking for trilobites next to a cement factory in middle July isn’t the “nicest fieldwork experience” for most of the people, but this fossil site has a special place in my heart.
