A collection of eurypterids from the Silurian of Lesmahagow collected pre 1900

Abstract

A rediscovered collection of scientifically significant eurypterid fossil specimens, assigned to Slimonia acuminata and Erettopterus bilobus, is held in the Doncaster Museum and Art Gallery. The specimens are from the historically important late Silurian Lesmahagow inlier of Lanarkshire, Scotland and are described herein. The material ranges from partial to complete specimens, with a wide range in size of both genera. Most specimens have either no or minimal damage. Some interesting features include the orientation and preservation of the eurypterids.
