Sacabambaspis (meaning "armor of Sacabamba") was a jawless fish that lived during the Ordovician period, inhabiting the shallow seas along the edge of Gondwana. It is a close relative of the well-known ancient fish, Aranda, which has numerous fossils. At least 30 Sacabambas fossils have been discovered, all from a very small area. This concentrated mortality is believed to have been caused by a large storm flooding its habitat with freshwater; the large number of lingula that died during the same period is also thought to be related to this event.
Several specimens of uncertain origin have been found in various countries corresponding to the edge of Gondwana: fossils possibly belonging to this genus were discovered in 1997 in strata in central Australia. Several scales with similar ornamentation to those of a species in Bolivia were also found in central Australia. Fossils of this genus have also been reported in Argentina. In 2009, researchers described specimens from the Amdeh Formation in Oman. The discovery in Oman confirms that these fish were distributed in the surrounding areas of the ancient supercontinent Gondwana, and not limited to the previously identified regions of South America and southern Australia.
On August 30, 2022, Kat Turk, a doctoral student in paleontology, posted a photo of a restored model of a Sakaban turtle taken at the Natural History Museum of Finland on her personal Twitter account. Its adorable expression sparked heated discussions on social media and became an internet meme.
