Huntoniatonia lingulifer Oklahoma Trilobite

Description: Huntoniatonia lingulifer is a Dalmanatid trilobite (Order: Phacopida; Suborder Phacopina; Superfamily: Dalmanitoidea; Family: Dalmanitidae) coming from the Lower Devonian strata of Coal County, Oklahoma. It is primarily distinguished from two other species of the genus from Oklahoma by the markedly longer pygidial spine. It is quite rare, comprising some 10% of the frequency of themore common Huntonia huntonesis.This trilobite was prepared by Bob Carroll, a world-renowned preparator of Oklahoma Devonian trilobites. Others may use less care, resulting in a less desirable specimen. This was one of two example of the species available at the Tucson show this year.
