Book excerpt: It is perhaps because fishes live in a buoyant medium, whether it be fresh or sea water, that they show a diversity in body shapes that is unparalleled by other vertebrates. There is also a unique diversity in the modes of reproduction, whether by external or internal fertilization, and this, with the morphology and fine structure of the reproducti

This book was released on 1995 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten synapomorphies are described that support the proposed sister group relationship of the Eocene Kushlukiidae and the Eocene to Recent Luvaridae as the superfamilial clade Luvaroidea at the node between the siganid and zanclid+acanthurid clades of acanthuroid fishes. The Kushlukiidae previously have been known only on the basis of Kushlukia permira Danilchenko from the Eocene of Turkmenistan, but another species of that age is shown to have been present in India; the latter is not given a new specific name because the two specimens of it are only fragments. In addition to the well known Recent species Luvarus imperialis, three fossil species have been referred to the Luvaridae: Proluvarus necopinatus Danilchenko from the Eocene of Turkmenistan is here recognied as a valid species of Luvarus, with Proluvarus becoming a junior synonym of Luvarus; Eoluvarus bondei Sahni and Choudhary from the Eocene of India is shown to be not a luvarid but, rather, a member of the fossil perciform family Exelliidae, the affinities of which family are poorly understood; Luvarus praeimperialis Arambourg from the Oligocene of Iran is shown to be not a luvarid but, rather, a representative of the new genus Aluvarus of such uncertain affinity that we simply place it incertae sedis among the percomorphs. Among the materials used by Danilchenko in the description of Proluvarus necopinatus only the holotype and the five other largest specimens (about 326-495 mm SL) represent that species. All of the other specimens are smaller than about 215 mm SL and represent two new species of a new genus of luvarid, Avitoluvarus dianae and A. mariannae. Numerous derived features are used to define both the Kushlukiidae and Luvaridae. Within the Luvaridae, the preponderance of derived features is found in Luvarus, whereas Avitoluvarus has only two unequivocal synapomorphies. The Luvaroidea, therefore, are represented by the Eocene Kushlukiidae with one genus and two species (Kushlukia permira and K. sp.) and the Luvaridae with one Eocene genus with two species (Avitoluvarus dianae and A. mariannae) and one genus, Luvarus, with one Eocene species, L. necopinatus, and one Recent species, L. imperialis.

This book was released on 1997 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four genera of fossil siganid fishes of early Eocene to early Oligocene age are recognized in addition to the single Recent genus. The osteological features of these five genera are described and illustrated. A phylogenetic analysis utilizing PAUP indicates that the genera have the following phyletic sequence convention: Ruffoichthys Sorbini (two species from the middle Eocene of Italy)--Eosiganus, new genus (one new species from the middle Eocene of Russia)--Siganopygaeus Danilchenko (one species from the early Eocene of Turkmenistan)--Protosiganus Whitley (one species from the early Oligocene of Switzerland)--Siganus Forsskål (27 Recent species in the Indo-Pacific).

Book excerpt: The Mesozoic era was an important time in the evolution of elasmobranch and actinopterygian fishes because it was then that most of the modern groups first entered the fossil record and began to radiate. By the end of the era, many archaic forms had disappeared and the foundation had been laid for the ichthyofauna that now exists. Despite this significant evolutionary change, there has been little concerted research done on Mesozoic fishes and no synopsis or compilation of the systematics and paleoecology of Mesozoic fishes has been published, not even for single groups. To remedy this deficiency, Gloria Arratia initiated the symposium "Mesozoic Fishes ? Systematics and Paleoecology". Its goal was to bring together paleontologists and other scientists studying Mesozoic fishes so that they might evaluate current research and form an active research group to press the investigation forward.The meeting generated fruitful discussions and new information that helps to clarify the course of piscine evolution at a crucial time. Phylogenetic relationships of the different groups were the central issue; but attention was given also to questions of biostratigraphy, functional anatomy, and the evolution of histological structures. The results of the symposium presented in this volumen reflect the current state of knowledge about Mesozoic fishes. The new findings described in the 36 papers and the disagreements among authors concerning the phylogenetic relationships of the fishes they have studied is an invitation to further research.
