Fish assemblages are a major 17 component of marine foods webs. The macroevolution and biogeographic patterns of 18 late Permian fish are currently insufficiently known. In this contribution, the late Permian 19 fish fauna from Kūmas quarry (southern Latvia) is described for the first time.

The site documents a fauna of Early Jurassic nektonic marine animals (five species of fishes, one species of marine crocodilian, two species of ichthyosaurs, cephalopods and crustaceans), but also over 20 spe- cies of insects. Unlike other fossil sites of similar age, the 3D preservation at Strawberry Bank provides unique evidence on palatal and braincase structures in the fishes and reptiles. The age of the site is important, documenting a marine ecosystem during recovery from the end-Triassic mass extinction, but also exactly coincident with the height of the Toarcian Oceanic Anoxic Event, a further time of turmoil in evolution. -

A Ne\T Prolacertiform Reptile from the Late Triassic of Northern Italy
Riv. It. Paleont. Strat. v. 100 n.2 pp. 285-306 tav. 1-3 Ottobre 1994 A NE\T PROLACERTIFORM REPTILE FROM THE LATE TRIASSIC OF NORTHERN ITALY SLVIO RENESTO Key-uords: Langobardisaurus pandolfii, New Genus, Reptilia, Diapsida, Late Triassic, Description, Palaeoecology. Riassunto. Vengono descritti due esemplari di Renili fossili raccolti a Cene (Val Seriana, Bergamo), nel Calcare di Zorzino (Norico Medio, Triassico Superiore). I due esemplari provengono dal medesimo strato e presentano caratteri scheletrici pressochè identici, per cui possono essere considerati conspecifici con ragione- vole cerf.ezza. Possono inohre essere classificati come appartenenti all' ordine dei Prolacertiformi. I confronti con i taxa già noti, consentono di ritenerli come appartenenti ad un genere ed una specie nuovi per la scienza: Langobardisaurus pand.olfii. Le caratteristiche dello scheletro suggeriscono infine che Langobardisaurus fosse un rettile terrestre e si nutrisse prevalentemente di insetti. Absúact. A new diapsid reptile is described from the locality of Cene (Seriana Valley, near Bergamo, Lombardy, Northern ltaly) from an outcrop of the Calcare di Zorzino (Zorzino Limestone) Formation (Middle Norian, Late Triassic). It is based on virtually identical specimens, differing only in size. Analysis of available diagnostic characters allows it to be included in the Prolacertiformes, represenring a new genus and species, Langobardisaurus pandolfi probably related to Macrocnemus, possibly to Cosesaums, and to the Tany- stropheìdae. It is assumed here that Langobardisaurus pandolfii was adapted to a terrestrial mode of life and probably to an insectivorous diet. Introduction. The Norian (Late Triassic) vertebrate localities from the Bergamo Prealps (Lom- bardy, Northern Italy) are of worldwide interest for the diversity and importance of their faunas. -

ABSTRACT - Perleidus sinensis n. sp., a new species of “Subholostean” fossil fish of the order Perleidiformes is described herein on the basis of a single, well-preserved specimen collected from the Upper Member of the Guanling Formation (Pelsonian, Middle Anisian, Middle Triassic) outcropping near Luoping (Yunnan Province) in South China. The vertebrate assemblage yielded by these levels is proving to be of importance with regard to the marine Triassic -

06_250317 part1-3.qxd 12/13/05 7:32 PM Page 15 Phylum Chordata Chordates are placed in the superphylum Deuterostomia. The possible rela- tionships of the chordates and deuterostomes to other metazoans are dis- cussed in Halanych (2004). He restricts the taxon of deuterostomes to the chordates and their proposed immediate sister group, a taxon comprising the hemichordates, echinoderms, and the wormlike Xenoturbella. The phylum Chordata has been used by most recent workers to encompass members of the subphyla Urochordata (tunicates or sea-squirts), Cephalochordata (lancelets), and Craniata (fishes, amphibians, reptiles, birds, and mammals). The Cephalochordata and Craniata form a mono- phyletic group (e.g., Cameron et al., 2000; Halanych, 2004). Much disagree- ment exists concerning the interrelationships and classification of the Chordata, and the inclusion of the urochordates as sister to the cephalochor- dates and craniates is not as broadly held as the sister-group relationship of cephalochordates and craniates (Halanych, 2004). Many excitingCOPYRIGHTED fossil finds in recent years MATERIAL reveal what the first fishes may have looked like, and these finds push the fossil record of fishes back into the early Cambrian, far further back than previously known. There is still much difference of opinion on the phylogenetic position of these new Cambrian species, and many new discoveries and changes in early fish systematics may be expected over the next decade. As noted by Halanych (2004), D.-G. (D.) Shu and collaborators have discovered fossil ascidians (e.g., Cheungkongella), cephalochordate-like yunnanozoans (Haikouella and Yunnanozoon), and jaw- less craniates (Myllokunmingia, and its junior synonym Haikouichthys) over the 15 06_250317 part1-3.qxd 12/13/05 7:32 PM Page 16 16 Fishes of the World last few years that push the origins of these three major taxa at least into the Lower Cambrian (approximately 530–540 million years ago). -

However, classical works linking the morphology and the function of the squamation in extant sharks suggest that, despite their limited taxonomic value, the study of isolated scales can be a useful tool for palaeoenvironmental and palaeoecological inferences. Following this idea, we have analyzed the fossil record of shark scales from two Middle Triassic sections of the Iberian Chain (Spain), identifying different functional types by means of a morphometric discriminant analysis. -
Body-Shape Diversity in Triassic–Early Cretaceous Neopterygian fishes: Sustained Holostean Disparity and Predominantly Gradual Increases in Teleost Phenotypic Variety
Body-shape diversity in Triassic–Early Cretaceous neopterygian fishes: sustained holostean disparity and predominantly gradual increases in teleost phenotypic variety John T. Clarke and Matt Friedman Comprising Holostei and Teleostei, the ~32,000 species of neopterygian fishes are anatomically disparate and represent the dominant group of aquatic vertebrates today. However, the pattern by which teleosts rose to represent almost all of this diversity, while their holostean sister-group dwindled to eight extant species and two broad morphologies, is poorly constrained. A geometric morphometric approach was taken to generate a morphospace from more than 400 fossil taxa, representing almost all articulated neopterygian taxa known from the first 150 million years— roughly 60%—of their history (Triassic‒Early Cretaceous). Patterns of morphospace occupancy and disparity are examined to: (1) assess evidence for a phenotypically “dominant” holostean phase; (2) evaluate whether expansions in teleost phenotypic variety are predominantly abrupt or gradual, including assessment of whether early apomorphy-defined teleosts are as morphologically conservative as typically assumed; and (3) compare diversification in crown and stem teleosts. The systematic affinities of dapediiforms and pycnodontiforms, two extinct neopterygian clades of uncertain phylogenetic placement, significantly impact patterns of morphological diversification. For instance, alternative placements dictate whether or not holosteans possessed statistically higher disparity than teleosts in the Late Triassic and Jurassic. Despite this ambiguity, all scenarios agree that holosteans do not exhibit a decline in disparity during the Early Triassic‒Early Cretaceous interval, but instead maintain their Toarcian‒Callovian variety until the end of the Early Cretaceous without substantial further expansions. After a conservative Induan‒Carnian phase, teleosts colonize (and persistently occupy) novel regions of morphospace in a predominantly gradual manner until the Hauterivian, after which expansions are rare.
