Description and paleobiogeographical implications of new Semlikiichthys (Teleostei, Perciformes) fish material from the Late Miocene deposits of Sahabi, Libya - 19/10/12
Abstract |
Fossils recently found in the Late Miocene of Sahabi, Libya, are attributed to the extinct species Semlikiichthys rhachirhinchus. This study enriches our knowledge of the anatomy of this species. The hyomandibula and, putatively, the operculum are for the first time attributed to Semlikiichthys. The fragile laminar supraoccipital crest in the dorsicranium is preserved complete. The material from Sahabi described here extends the Late Miocene distribution of the species to the north and west to include Libya. The paleobiogeographic distribution of Semlikiichthys in Africa, and the freshwater faunal connections between different hydrographical basins in north central Africa, are discussed.
