Rare, Ordovician Trilobite (Dionide?) - Portugal

This is a rare, Ordovician trilobite from Portugal. It came out of a collection we recently purchased that had it identified as Dionide mareki. It does appear at least the genus is correct. Like most material from Portugal it is fairly heavily distorted due to geological forces.
