    COMMENTS Copeia, (4), pp. Comments on Basal Teleosts and Teleostean Phylogeny, by Gloria Arratia COLIN PATTERSON For more than 20 years, Gloria Arratia has been a prolific contributor on Mesozoic fossil fishes and on the skeletal ontogeny and mor-phology of Recent teleosts. Often writing with her husband, Hans-Peter Schultze, she. The caudal skeleton in Eohiodon is nearly identical to that in Hiodon. The traditionally accepted Notopteroidei, containing Lycopteridae, Hiodontidae, and Notopteridae, is a polypheletic group. The Asian fossil family Lycopteridae is not more closely related to Hiodontidae than it is to other taxa in the Osteoglossomorpha, but is sister to all.

The caudal portion of the skeleton and the caudal fin are remarkably well preserved. This is perhaps the best specimen yet known for this part of the body (Fig. 3). The substantial number of specimens of this species and the precise determination of the Pierre Shale zones from which it is known enable a clearer perspective on its.

Abstract. The diural caudal skeleton of teleostean actinopterygians develops phylogenetically and ontogenetically from a polyural skeleton. The reduction of the polyural anlage to four, three, two or fewer centra in the adult caudal skeleton takes different pathways in different genera (e.g.

compare Elops and Albula) and groups of a result, ural centra are not homologous Cited by: The caudal skeleton of teleost fishes of the order Cyprinodontiformes is described and compared on the basis of ex-tant and eight fossil species, supporting delimitation of 21 phylogenetic.

Naiathaelon okkidion nov. gen. nov. sp., previously reported as Anaethalion, is defined from the Eaply Tithonianof Canjuers (Var, France).Its combination of plesiomorphic and apomorphic characters leads to consider it as an Elopomorpha incertae genus Anaethalion is therefore restricted to Bavarian and Cerin outcrops.

14 figs., 2 tabs., 3 apps.] The interrelationships of fossil and Recent gonorynchid fishes are reviewed. The monophyly of the family is cladistically verified, in part, by caudal skeleton and dentition. On the other hand, in the derived diural pattern, present in extant teleosts, these 1-to-1 relationships were lost, and the adult caudal skeleton generally comprises two ural centra (U1 and U2 D), the first of which supports the lower hypurals (H1 and H2), and the second supports the upper hypurals (see e.g.: Elops, Hiodon, Thymallus, Sprattus.

The middle panel shows literature interpretations of caudal fin function (in lateral view) with the hypothesized axis of bending and direction of thrust (Affleck, ).Two alternative thrust directions are shown.

When compared with Patterson and Rosen's figure of the caudal skeleton of Crossognathus, the fragmentary caudal material from KUKUSMMand UT supports their conclusions. In Apsopelix uroneurals 1 and 2 extend forward to the second preural centrum and the third uroneural extends forward to the first preural centrum.

In the past, epural bones of teleost fishes have been labeled sequentially from anterior to posterior (e.g., epural 1, epural 2, etc.) without regard to their position relative to centra and ventral elements of the caudal fin.

Zool. Scripta, 7: Parenti, L. L A phylogenetic and biogeo- graphic analysis of cyprinodontiform fishes (Teleostei, Atherinomorpha). Late Jurassic fishes of the Solnhofen limestone of Bavaria, southern Germany, have been known for over years and are currently known by (including Ebertichthys) formally described actinopterygian species (Schultze, table 5).The earliest illustrations showing a fish – which would correspond to what it is currently interpreted as Tharsis dubius (Blainville, ) – appeared in.

The two plates of connective tissue, the two types of distal caudal radials, and the space between hypurals 2 and 3 are also apparent (but generally not commented on) in previously published figures of other gar species; thus, we conclude that these three features represent anatomical properties of the caudal fin skeleton that were likely.

The caudal skeleton began to develop hypaxially between 10 and 12 mm TL along with the initial upward flexion of the notochord around the putative first hypural (Fig. 2O, white triangle), as in another reported specimen (Bemis and Grande, ).

At that stage, actinotrichia were present both ventral and dorsal to the notochord (Fig. 2O.Taxonomic framework and the names of higher clades. Although the monophyly of extant teleosts and their close phylogenetic relationships to several fossil taxa is generally well established and widely accepted, the delimitation of Teleostei has been problematic [33, 34].Due to the long tradition of essentialist thinking in taxonomy [], after the original definition of Müller [] and the.
