Description
Protaspis bucheri
Lower Devonian (Seigenian)
Bear Tooth Butte Formation
Lower Cottonwood Canyon, near Lovell
Wyoming, USA.
Ostracoderms were among the earliest armored vertebrates, characterized by protective bony plates covering the head and body. Fossils of Protaspis are uncommon, making preserved headshields important records of these primitive fish and their anatomy.
32mm ostracoderm headshield on 55mm slab. Very rare.
