Sorbitorhynchus is an extinct genus of prehistoric sarcopterygians, or lobe-finned fish. Fossils of this genus of marine lungfish have been found in Guangxi, China. [1] The only described species in this genus is Sorbitorhynchus deleaskitus,[2] but the holotype for this species may show some unusual malformations and thus not be useful for taxonomic or phylogenetic analysis.[3]
