Kettneraspis williamsi

A very spiny trilobite from Oklahoma called Kettneraspis williamsi. This specimen (PE 56119) is from the Early Devonian rocks of the Arbuckle Mountains of Oklahoma and is over 400 million years old. It was described and named by Harry B. Whittington, a paleontologist at the University of Cambridge in 1956. Whittington named the species after Sir Alwyn Williams, a Welsh geologist who’s research focused primarily on fossil brachiopods and who collected the specimen of this trilobite from Oklahoma that eventually became the holotype.
