 Various phylogenetic studies, based on morphology, have concluded that the blind shark lineage represents the sister taxon to the wobbegongs.Blind shark fossils have been found in Late Cretaceous period (99.6–65.5 Ma) deposits from Europe, as well as in Pliocene epoch (5.3–2.6 Ma) deposits from Chile and Peru.A number of other "Brachaelurus" species are also known from the fossil record.
