Thryonomyidae was formerly more diverse and widespread, with fossil relatives found in India and Arabia as well.[1]
The extinct genus Sacaresia from the island of Mallorca off Spain may also be a member of this family,[2] though its position remains uncertain.
Former fossil members of the family include the genus Apodecter and two species of Paraphiomys (australis and roessneri), which have now been transferred to the related Petromuridae.[3]
