Ymboirana was an extinct genus of caecilian described based on a fossil found in the OligoceneTremembé Formation (Taubaté Basin), Brazil. The holotype and only known specimen comprises a partially preserved skeleton, including parts of the skull and vertebral column. Ymboirana was identified as an extinct representative of the family Typhlonectidae, a subgroup of caecilians well known because its members, unlike all other living caecilians, exhibit an aquatic or semi-aquatic lifestyle when adults.[1]
