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. While the name seems like a typo, it is the result of the fact that the original genus Huntonia was found to be preoccupied by an Isopod. It is primarily distinguished from two other species of genus from Oklahoma by the markedly longer pygidial spine. It is quite rare, comprising some 10% of the frequency of the more common Huntoniatonia 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. Notice the fine eye facets preserved here, particularly in the right eye. See my other offerings for an example of Huntoniatonia huntonesis.
