Fayolia is a genus of fossil egg capsule, widely thought to have been produced by xenacanths. [1] The egg is elongate and tapers towards both ends, and surrounded by helically twisted collarettes, with one end (the beak) having a tendril. [2]
It is predominantly known from freshwater deposits with 16 species spanning a stratigraphic range from the Late Devonian to the Middle Triassic. [2] A new species, Fayolia sharovi, was described in 2011 from lacustrine deposits of the Middle Triassic Madygen Formation in Kyrgyzstan, Central Asia. [3]
