Basal teleosts and teleostean phylogeny

More about the book

Complete descriptions, as preservation permits, are provided for new Jurassic taxa (e.g., Cavenderichthys talbragarensis n.gen. from Australia, Elops-like species and leptocephalous larvae, Leptolepides haerteisi n.sp., Orthogonikleithrus hoelli n.sp. and Tischlingerichthys viohli n.gen. et sp. from Germany); redescriptions of some South American Oxfordian teleosts (e.g., Chongichthys dentatus) and re-evaluation of the composition of the Jurassic family Varasichthyidae and the phylogenetic position of the Late Jurassic genera Ascalabos, Tharsis, Leptolepides and the Cretaceous genus Erichalcis are given. The relationships among Jurassic teleosts from Europe, Middle America, South America and Australia, the ?Early Cretaceous osteoglossomorph Lycoptera, the Early Cretaceous ostariophysan Gordichthys and clupeomorph Santanaclupea, the Cretaceous and Tertiary clupeomorph Diplomystus, the Cretaceous "salmoniforms" Erichalcis and Humbertia and the extant Elops, Hiodon, Chanos, Denticeps, Engraulis, Esox, Umbra, Oncorhynchus and Thymallus are evaluated based on 135 unweighted morphological characters by using cladistic principles...
