We described a Late Cretaceous fish fauna from the Campanian-age Blufftown Formation in western Georgia (Case and Schwimmer, 1988), including 15 selachian taxa and 8 osteichthyans; however, at that time no chimaeras had been found in the region. A well-preserved specimen of Ischyodus bifurcatus Case, 1978, was subsequently collected from the same general locality described in the above study, but in the immediately superjacent Cusseta Formation. This is a note of the new occurrence of this fish and a summary of its known geographic and stratigraphic distribution (Appendix).

We describe isolated teleostean teeth found in no association with the jaw bone. The specimens have been recovered in Late Cretaceous marine deposits of the Vivian Formation in the Peruvian Sub-Andean Region. The deposition sequence from where the teeth come is interpreted as a shallowing-upward sequence of low salinity. The fish material is identified as Enchodus aff. E. gladiolus based on the presence of a small but well-developed post-apical barb, an anterior cutting edge, the crown is symmetrical in cross-section, have a sigmoidal profile, and bears strong ridges (=striations). The Peruvian material differs from the typical E. gladiolus teeth in having a faintly serrated anterior cutting edge which is absent in most specimens referred to E. gladiolus. We also highlight that taxonomic assignments made based on isolated teeth must be taken with care. Despite scarce, the material recovered denotes that the marine units of Peru can give valuable information about the Pacific fish fauna during the Late Cretaceous.

A new Devonian fossil fish fauna from the region of Caño Colorado between the Rio Palmar and Rio Socuy, Sierra de Perijá, Venezuela, comes from two localities and several horizons within the Campo Chico Formation, dated on plants and spores as Givetian-Frasnian in age. Placoderms are most common, with the antiarch <i>Bothriolepis perija</i> n. sp., showing affinity with species from the Aztec fish fauna of Victoria Land, Antarctica. A second antiarch, <i>Venezuelepis mingui</i> n.g. n.sp., is also closely related to an Antarctic species, which is reassigned to this new genus. Fragmentary remains of a phyllolepid placoderm show similarity to the genus <i>Austrophyllolepis</i> from southeastern Australia. Chondrichthyan spines are provisionally referred to the Antarctilamnidae, and acanthodian remains include spines of the widespread taxon <i>Machaeracanthus</i>. Osteichthyans are represented by osteolepid and dipnoan scales and teeth, and scales lacking cosmine which may belong to another major taxon. This fauna has provided the first Devonian record from South America of three major fish groups: antiarch and phyllolepid placoderms, and dipnoans. These are widely distributed on most other continents. Although invertebrates and plants from the same sequence closely resemble those of eastern North America, the endemic elements in the fish fauna indicate Gondwana affinities. Phyllolepid placoderms are common in Givetian-Frasnian strata of Australia and Antarctica, but are only known from the Famennian in the Northern Hemisphere. The new phyllolepid occurrence extends their range across the northern margin of Palaeozoic Gondwana. The age and affinities of this new fish fauna are consistent with a model of biotic dispersal between Gondwana and Euramerica at or near the Frasnian-Famennian boundary. A narrow marine barrier separating northern and southern continental landmasses is indicated, in contrast to the wide equatorial ocean for the Late Devonian postulated from palaeomagnetic data. <br><br> Es wird eine neue devonische Fischfauna aus dem Gebiet zwischen Caño Colorado und Rio Socuy, Sierra de Perijá, beschrieben. Die Funde stammen aus zwei Lokalitäten und mehreren Horizonten innerhalb der Campo Chico Formation, die auf Grundlage von Untersuchungen der Pflanzen- und Sporenfunde dem Zeitabschnitt Givetium-Frasnium zugeordnet werden. Placodermen sind durch den Antiarchen <i>Bothriolepis perija</i> n. sp. häufig vertreten. Sie sind mit Arten der Aztec-Fischfauna von Viktoria Land, Antarktis, verwandt. Ein zweiter Antiarche, der <i>Venezuelepis mingui</i> n. g. n. sp. ist eng mit einer Spezies aus der Antarktis verwandt, die ebenfalls dieser neuen Gattung zugeschrieben wird. Fragmentarische Reste eines phyllolepiden Placodermen weisen Ähnlichkeiten mit der Gattung <i>Austrophyllolepis</i> aus dem Südosten Australiens auf. Wirbel eines Chondrichthyer werden vorläufig den Antarctilamnidae zugeschrieben. Acanthodir-Reste schließen das weitverbreitete Taxon <i>Machaeracanthus</i> ein. Osteichthyer sind durch Schuppen und Zähne osteolepider Sarcopterygier und Dipnoi vertreten. Andere Schuppen, denen die Cosminschicht fehlt, gehören vermutlich zu einem anderen Haupttaxon. Damit ist durch diese Fauna der erste Nachweis für das Vorkommen der drei Hauptfischgruppen Antiarchi, phyllolepide Placodermi und Dipnoi im Devon Südamerikas erbracht. Sie sind auch auf den meisten anderen Kontinenten weit verbreitet. Obwohl Invertebraten und Pflanzen aus derselben Zeit sehr denen aus dem Osten Nordamerikas ähneln, weisen die endemischen Elemente in der Fischfauna auf eine Affinität zu Gondwana hin. Phyllolepide Placodermen sind im Givetium-Frasnianium Australiens verbreitet, aber erst aus dem Famennium in der Nordhemisphere bekannt. Das Auftreten eines neuen Phyllolepiden weitet den Vorkommensbereich über die nördliche Linie des paläozoischen Gondwanas hinaus aus. Alter und Verwandtschaftsbeziehungen dieser neuen Fischfauna stimmen mit dem Modell der biotischen Verbreitung zwischen Gondwana und Euramerika an bzw. nah an der Frasnium-Famennium-Grenze überein. Es gibt Hinweise für eine die nördlichen und südlichen Landmassen trennende schmale Meerenge. Dies steht im Gegensatz zur Annahme eines weiten äquatorialen Ozeans im späten Devons, die sich auf palaeomagnetische Daten stützt. <br><br> doi:<a href="http://dx.doi.org/10.1002/mmng.20020050111" target="_blank">10.1002/mmng.20020050111</a>

Abstract A fossil fish remnants from the Early Pliocene strata of the Dniester valley (Republic of Moldova) are described in the paper. Seven species, belonging to 6 genera, 4 families and 4 orders (Acipenseriformes, Cypriniformes, Siluriformes, Esociformes) were identified in Nikolskoe and Uyutnoe localities. All of them are analogues of extant taxa. A brief review of development of the freshwater fish fauna in the Lower Dniester Basin during the Early Pliocene is presented.

In April, 1879, William Davies published in the GeologicalMagazine (n.s., Dec. II, Vol. VI. pp. 145–8) a paper on “Some Fish Exuviæ from the Chalk, generally referred to Dercetis elongatus, Ag.; and on a new species of Fossil Annelide, Terebella Lewesiensis”. Herein he discussed certain longitudinal or tubular agglomerations of fish-debris, originally named Murœna(?) Lewesiensis, by G. A. Mantell, but subsequently assigned by L. Agassiz to the fish described by him as Dercetis elongatus. References to the various papers and books in which these remains had been mentioned will be found in the paper quoted. From his profound knowledge of fossil fish Davies was able to show that these agglomerations contained the remains of more than one species of fish, and he considered that the fragments had been collected and affixed to their tubes by annelids allied to the modern Terebella. It is well known that some living species of that genus have similar tube-building habits, so that the suggestion made by Davies has been generally accepted, and the specimens in the British Museum on which he based his conclusions have since then been labelled Terebella(?) Lewesiensis Mantell sp.

We studied fish otoliths from twelve sediment samples of a well-preserved late Pliocene to early Pleistocene fauna originally from the northwest Philippines that were originally deposited in relatively deepwater marine environment. The fish fauna is systematically described, its paleoenvironmental character is explored, and its diversity is analyzed. Four unknown species have been encountered: Parascombrops schwarzhansi n. sp., Maurolicus sp., Pteropsaron sp., and Priolepis sp., of which one is described as new species and three were left in open nomenclature as their local recent counterparts are not well known yet. In addition, a variant Benthosema, Benthosema aff. fibulatum, is described. Overall, fifty-three taxa of fish otoliths were found, of which eighteen were identified at the species level and an additional twenty-seven at the genus level. Most extant species nowadays occur around the Philippines in relatively deep water (about 200 m depth), which is congruent with earlier studies on mollusks and echinoderms from the same deposits. This is the first study on a fossil fish otolith assemblage from the Philippines. Its diversity is very high and analysis by rarefaction curves suggests that additional sampling would add more fish species to the presented fauna list.

Since the publication of the notes on some new fishes from the English Purbeck and Wealden Beds five years ago, the Rev. W. R. Andrews, of Teffont, has kindly entrusted to the writer for examination a fine series of Purbeckian fishes from the Vale of Wardour. All the members of this fauna are remarkably diminutive, compared with those met with in the corresponding formation in Dorsetshire; but nearly all the species are well preserved, and some are sufficiently novel to be worthy of detailed description. The Pycnodont genus Mesodon, which was first described from the English Purbeck in the paper already cited, is here represented by one or two more forms; the Lepidosteoid Macrosemius is now first definitely recorded as a British fossil; additional examples of Pleuropholis extend previous information of that genus; new specimens of Leptolepis Brodiei add to the known specific characters of this fish; and the opportunity is now afforded for publishing a figure of the small Palæoniscid, Coccolepis andrewsi.
