Abstract
a genus of early pteraspidomorph craniates in the order Arandaspidiformes, closely related to Arandaspis and among the earliest whole-body specimens of ostracoderms. Jawless and 10 inches long, Sacabambaspis had a laterally flattened body covered with scales, and its extended tail ended in a small fin web; it had no paired fins. Its blunt head was armored with bony plates, with forward-facing eyes. First found in Bolivia, it is known from several Gondwanan locations: Argentina, Australia, and the Arabian Peninsula; Middle to Late Ordovician, 470–453 Ma.
