Fayolia

Fayolia is a prehistoric shark egg capsule morphotype of the family Xenacanthidae.[1][2] It is predominantly known from freshwater deposits with a stratigraphic range from the Late Devonian to the Triassic. A new species, Fayolia sharovi, was described in 2011 from lacustrine deposits of the Middle Triassic Madygen Formation in Kyrgyzstan, Central Asia.[3]
