Abstract
The Henryhouse Formation is mainly composed of argillaceous limestones with inferred environments of deposition from shallow subtidal to supratidal. The upper member of the formation is Ludfordian–late Přídolí in age and contains a moderately diverse trilobite fauna. The environment of deposition was likely a low-energy, shallow marine carbonate ramp. The fauna was originally described by Campbell in 1967 and since then additional taxa have been discovered by vocational paleontologists.
Campbell's work identified eleven species of trilobites assigned to ten genera in the Henryhouse. A single new species of aulacopleurid was described in 1996. Continued collection has yielded eight new species. A total of twenty species assigned to sixteen genera is now recognized from the unit. New trilobite taxa from the Henryhouse include two new species of Huginarges and new species of Paciphacops, Cheirurus, Dalmanites, Calymene, Ceratocephala, Kettneraspis, and Scotoharpes.
