trilobite, Angelina sedgwickiiWhile, is named for Rev. Adam Sedgwick,
who coined the term Cambrian. Most trilobites from the region are
quite distorted by geological forces, but this one is quite three
dimensional in preservation and has intact genal spines. This specimen
is from the type locality in North Wales.
