Boii is an extinct genus of microsaur within the family Tuditanidae.[1] It was found in Carboniferous coal from mines near the community of Kounov in the Czech Republic. The only remains of the genus consist of a crushed skull, shoulder girdle bones, and scales, which were similar to microsaurian elements originally referred to Asaphestera. Boii can be characterized by its heavily sculptured skull, thin ventral plate of the clavicles, and a larger number of fangs on the roof of the mouth.[2] For many years the type and only known species, Boii crassidens, was considered to be a species of Sparodus,[3] until 1966 when Robert Carroll assigned it to its own genus.[4]
