Sacabambaspis (scientific name: Sacabambaspis, meaning "Armor of Sacabamba") is a jawless fish that lived in the Ordovician period. It inhabits the shallow sea on the edge of Gondwana. A close relative of the Aranda softshell turtle, a famous ancient fish with numerous fossils. At least 30 Sakaban soft-shell turtle fossils have been discovered, all from a very small area. This concentration of death in one place is believed to be caused by a large storm causing freshwater to flow into its habitat. The large number of lingual clams that died during the same period is also believed to be related to this event.

Some specimens that cannot be completely identified have been found in many countries corresponding to the margins of Gondwana: in 1997, fossils that may belong to this genus were found in some strata in central Australia. Several scales with similar patterns to those found in Bolivia have also been found in central Australia. Fossils of this genus have also been reported in Argentina. In 2009, researchers also described specimens from the Amdeh Formation in Oman. The discovery in Oman confirms that these fish are distributed in the surrounding areas of Gondwana and are not limited to the confirmed areas of South America and southern Australia.
