Lombardy 2012 Part A
Pan-European Correlation of the Triassic 9th International Field Workshop September 1-5, 2012 The Middle-Late Triassic of Lombardy (I) and Canton Ticino (CH) By Flavio Jadoul and Andrea Tintori 2 This Field Trip had support from: Convenzione dei Comuni italiani del Monte San Giorgio/UNESCO Fondazione UNESCO- Monte San Giorgio Svizzera Comunità Montana della Valsassina, Valvarrone, Val d’Esino e Riviera Parco Regionale della Grigna Settentrionale 3 September 2, first day by Andrea Tintori and Markus Felber MONTE SAN GIORGIO IS UNESCO WORLD HERITAGE SITE Monte San Giorgio is among the most important fossil-bearing sites in the world, in particular concerning the middle Triassic fauna (245-230 million years ago). Following the UNESCO inscription of the Swiss side of the mountain in 2003, the Italian side has been inscribed in 2010, stating that: “Monte San Giorgio is the only and best known evidence of the marine Triassic life but also preserves some important remains of terrestrial organisms. The numerous and diverse fossil finds are exceptionally preserved and complete. The long history of the research and the controlled management of the paleontological resources have allowed thorough studies and the classification of exceptional specimens which are the basis for a rich scientific paper production. For all these reasons Monte San Giorgio represents the main reference in the world concerning the Triassic faunas.” 4 THE GEOLOGICAL HISTORY OF MONTE SAN GIORGIO Monte San Giorgio belongs to the broad tectonic feature named Sudalpino , which encompasses all the rock formations lying South of the Insubric Line. The oldest rocks of Monte San Giorgio outcrop in spots along the shores of the Ceresio Lake, between the Brusino Arsizio custom house and the built-up area of Porto Ceresio. -

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). -

Unitat d'Alcover. Resum: Els fòssils de les dolmicrites d'Alcover es coneixen des del 1963. La Unitat de les Dolomies Taulejades d'Alcover (pedra d'Alcover) té una potència de 70-80 m, i es troba en depressions interesculls. Estratigràficament es situa al Ladinià superior (Triàsic mitjà). Durant la deposició de la Unitat d'Alcover es van desenvolupar condicions anòxiques i hipersalines d'una forma periòdica. Les fàcies més abundants són constituïdes per capes de dolmicrites massives (d'entre 1 i 10 cm de gruix) i dolmicrites laminades molt fines. Localment apareixen capes ondulades amb plegaments i cabussaments. L'associació fòssil és al·lòctona i composta per grups florístics i faunístics com: plantes terrestres, celenterats, braquiòpodes, mol·luscs, artròpodes, equinoderms, peixos i rèptils, però la reputació d'aquests jaciments rau en el fet que els fòssils s'han conservat en dolmicrites i en la seva diversitat ictiològica. La fauna de peixos d'Alcover es caracteritza bàsicament per individus de talla mitjana. Els Saurichtiformes i els Perleidiformes són els ordres més comuns. Mitjançant aquest estudi els actinopterigis es classifiquen bàsicament a nivell genèric, i en alguns casos només a nivell de família. D'aquesta manera, i fins avui, han sigut prèviament indentificats 15 gèneres pertanyents a 11 famílies i nou ordres: Plycholepis, IBoreosomiis, Sauriclitliys, Colobodiis, Perleidus, IClenognaliclilltys, Peltoperleidiis, ICleithrolepididae indet., Pelíopleurus, Peripeltopleurus, IPlatysiagiim, Liiganoia, Eosemionotiis, Archaeosemionotus, Allolepidotiis, Eoeugnathiis, ICaturus, lOphiopsis, IPholidophoridae indet. -
A Hiatus Obscures the Early Evolution of Modern Lineages of Bony Fishes
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2021 A Hiatus Obscures the Early Evolution of Modern Lineages of Bony Fishes Romano, Carlo Abstract: About half of all vertebrate species today are ray-finned fishes (Actinopterygii), and nearly all of them belong to the Neopterygii (modern ray-fins). The oldest unequivocal neopterygian fossils are known from the Early Triassic. They appear during a time when global fish faunas consisted of mostly cosmopolitan taxa, and contemporary bony fishes belonged mainly to non-neopterygian (“pale- opterygian”) lineages. In the Middle Triassic (Pelsonian substage and later), less than 10 myrs (million years) after the Permian-Triassic boundary mass extinction event (PTBME), neopterygians were already species-rich and trophically diverse, and bony fish faunas were more regionally differentiated compared to the Early Triassic. Still little is known about the early evolution of neopterygians leading up to this first diversity peak. A major factor limiting our understanding of this “Triassic revolution” isaninter- val marked by a very poor fossil record, overlapping with the Spathian (late Olenekian, Early Triassic), Aegean (Early Anisian, Middle Triassic), and Bithynian (early Middle Anisian) substages. Here, I review the fossil record of Early and Middle Triassic marine bony fishes (Actinistia and Actinopterygii) at the substage-level in order to evaluate the impact of this hiatus–named herein the Spathian–Bithynian gap (SBG)–on our understanding of their diversification after the largest mass extinction event of the past. I propose three hypotheses: 1) the SSBE hypothesis, suggesting that most of the Middle Triassic diver- sity appeared in the aftermath of the Smithian-Spathian boundary extinction (SSBE; 2 myrs after the PTBME), 2) the Pelsonian explosion hypothesis, which states that most of the Middle Triassic ichthyo- diversity is the result of a radiation event in the Pelsonian, and 3) the gradual replacement hypothesis, i.e. -

As a first step, we present here the available data from the Catalonian and Pyrenean basins (NE of the Iberian Peninsula), offering new insights on the diversity and temporal distribution of their vertebrate faunas. The two basins have yielded unexpectedly abundant and diverse vertebrate assemblages, including fishes, amphibians and reptiles from continental and marine environments. -

Email: [email protected] urn:lsid:zoobank.org:author:55EA63EE-63FD-49E6-A216-A6D2BEB91B82 Abstract. The family-group names of animals (superfamily, family, subfamily, supertribe, tribe and subtribe) are regulated by the International Code of Zoological Nomenclature. Particularly, the family names are very important, because they are among the most widely used of all technical animal names. A uniform name and spelling are essential for the location of information. To facilitate this, a list of family- group names for fossil fishes has been compiled. I use the concept ‘Fishes’ in the usual sense, i.e., starting with the Agnatha up to the †Osteolepidiformes. All the family-group names proposed for fossil fishes found to date are listed, together with their author(s) and year of publication. The main goal of the list is to contribute to the usage of the correct family-group names for fossil fishes with a uniform spelling and to list the author(s) and date of those names. No valid family-group name description could be located for the following family-group names currently in usage: †Brindabellaspidae, †Diabolepididae, †Dorsetichthyidae, †Erichalcidae, †Holodipteridae, †Kentuckiidae, †Lepidaspididae, †Loganelliidae and †Pituriaspididae.

The discovery and following first studies had already shown their important implications not only for paleontology but also for paleogeography. One advantage of fishes over marine reptiles is their size when we want to recognize an assemblage and compare it to others. Fishes indeed are far smaller and more numerous than reptiles, so that the chances to have a ‘complete’ fish assemblage are much higher. We believe that very fast migrations were possible, but not all the fishes were either interested or able to travel such a long distance. Oceanic currents in the Tethys had clockwise direction in the northern hemisphere, making westwards migration easier in the tropical region where our fishes lived.

Zhejiang Museum of Natural History, Hangzhou, Zhejiang 310014, People’s Republic of China http://dx.doi.org/10.1098/rsbl.2015.0604 Our recent studies on Potanichthys [1] and Wushaichthys [2] from China shed new light on the evolutionary origin and reproductive strategy of the Thoracopteridae. Received: 24 July 2015 Tintori commented on our taxonomic assignment of Wushaichthys and on our Accepted: 21 September 2015 hypotheses of gradual evolution of over-water gliding adaption and internal fertilization of thoracopterids [3–5]. Moreover, he questioned the provenance and age of Potanichthys [1] and Wushaichthys [2], and claimed that Potanichthys xingyiensis was a younger synonym of Thoracopterus wushaensis [5]. However, we do not agree with him on these points because Tintori’s commentary is not based on a phylogenetic analysis and lacks supportive evidence. The taxonomy should be based on the results of phylogenetic analysis, not the reverse. Our phylogenetic studies [2] indicate that the traditional, poorly defined family Peltopleuridae is paraphyletic; the previously alleged ‘pelto- pleurid’ Peripeltopleurus [6] and the recently described Wushaichthys [2] are more closely related to four-winged thoracopterids than to Peltopleurus because they possess ambiguous features of Thoracopteridae.
