New Mexico Museum of Natural History and Science Bulletin 35. 193 ANNOTATED CHECKLIST OF FOSSIL FISHES FROM THE SMOKY HILL CHALK OF THE NIOBRARA CHALK (UPPER CRETACEOUS) IN KANSAS KENSHU SHIMADA1 AND CHRISTOPHER FIELITZ2 1Environmental Science Program and Department of Biological Sciences, DePaul University,2325 North Clifton Avenue, Chicago, Illinois 60614; and Sternberg Museum of Natural History, Fort Hays State University, 3000 Sternberg Drive, Hays, Kansas 67601;2Department of Biology, Emory & Henry College, P.O. Box 947, Emory, Virginia 24327 Abstract—The Smoky Hill Chalk Member of the Niobrara Chalk is an Upper Cretaceous marine deposit found in Kansas and adjacent states in North America. The rock, which was formed under the Western Interior Sea, has a long history of yielding spectacular fossil marine vertebrates, including fishes. Here, we present an annotated taxo- nomic list of fossil fishes (= non-tetrapod vertebrates) described from the Smoky Hill Chalk based on published records. Our study shows that there are a total of 643 referable paleoichthyological specimens from the Smoky Hill Chalk documented in literature of which 133 belong to chondrichthyans and 510 to osteichthyans. These 643 specimens support the occurrence of a minimum of 70 species, comprising at least 16 chondrichthyans and 54 osteichthyans. Of these 70 species, 44 are represented by type specimens from the Smoky Hill Chalk. However, it must be noted that the fossil record of Niobrara fishes shows evidence of preservation, collecting, and research biases, and that the paleofauna is a time-averaged assemblage over five million years of chalk deposition. -

However, studies of morphological rates of change have lagged behind those on taxonomic diversification, and most authors have focused on continuous characters and quantifying patterns of morphological rates over time. Here, we provide a phylogenetic approach, using discrete characters and three statistical tests to determine points on a cladogram (branches or entire clades) that are characterized by significantly high or low rates of change. These methods include a randomization approach that identifies branches with significantly high rates and likelihood ratio tests that pinpoint either branches or clades that have significantly higher or lower rates than the pooled rate of the remainder of the tree. As a test case for these methods, we analyze a discrete character dataset of lungfish, which have long been regarded as “living fossils” due to an apparent slowdown in rates since the Devonian. -
35-51 New Data on Pleuropholis Decastroi (Teleostei, Pleuropholidae)
Geo-Eco-Trop., 2019, 43, 1 : 35-51 New data on Pleuropholis decastroi (Teleostei, Pleuropholidae), a “pholidophoriform” fish from the Lower Cretaceous of the Eurafrican Mesogea Nouvelles données sur Pleuropholis decastroi (Teleostei, Pleuropholidae), un poisson “pholidophoriforme” du Crétacé inférieur de la Mésogée eurafricaine Louis TAVERNE 1 & Luigi CAPASSO 2 Résumé: Le crâne et le corps de Pleuropholis decastroi, un poisson fossile de l’Albien (Crétacé inférieur) du sud de l’Italie, sont redécrits en détails. P. decastroi diffère des autres espèces du genre par ses deux nasaux en contact médian et qui séparent complètement le dermethmoïde ( = rostral) des frontaux. Avec son maxillaire extrêmement élargi qui couvre la mâchoire inférieure et son supramaxillaire fortement réduit, P. decastroi semble plus nettement apparenté avec Pleuropholis cisnerosorum, du Jurassique supérieur du Mexique, qu’avec les autres espèces du genre. Par ses mâchoires raccourcies et ses nombreux os orbitaires, Pleuropholis apparaît également comme le genre le plus spécialisé de la famille. La position systématique des Pleuropholidae au sein du groupe des « pholidophoriformes » est discutée. Mots-clés: Pleuropholis decastroi, Albien, Italie du sud, Pleuropholis, Pleuropholidae, “Pholidophoriformes”, ostéologie, position systématique. Abstract: The skull and the body of Pleuropholis decastroi, a fossil fish from the marine Albian (Lower Cretaceous) of southern Italy, are re-described in details. P. decastroi differs from the other species of the genus by their two nasals that are in contact along the mid-line, completely separating the dermethmoid (= rostral) from the frontals. With its extremely broadened maxilla that covers the lower jaw and its strongly reduced supramaxilla, P. decastroi seems more closely related to Pleuropholis cisnerosorum, from the Upper Jurassic of Mexico, than to the other species of the genus. -
The Scales of Mesozoic Actinopterygians
Mesozoic Fishes – Systematics and Paleoecology, G. Arratia & G. Viohl (eds.): pp. 83-93, 6 figs. © 1996 by Verlag Dr. Friedrich Pfeil, München, Germany – ISBN 3-923871–90-2 The scales of Mesozoic actinopterygians Hans-Peter SCHULTZE Abstract Cycloid scales (elasmoid scales with circuli) are a unique character of teleosts above the level of Pholidophorus and Pholidophoroides. Cycloid scales have two layers. A bony layer, usually acellular, is superimposed on a basal plate composed of partially mineralized layers of plywoodlike laminated collagen fibres. The tissue of the basal layer is refered to here as elasmodin. Basal teleosts (sensu PATTERSON 1973) possess rhombic scales with a bony base overlain by ganoin (lepidosteoid ganoid scale). Amioid scales (elasmoid scales with longitudinally to radially arranged ridges or rods on the overlapped field) are found within halecomorphs. This scale type evolved more than once within primitive actinopterygians and other osteichthyan fishes. It may have even developed twice within halecomorphs, in Caturidae and Amiidae, from rhombic scales of lepidosteoid type. Some basal genera of halecomorphs show remains of a dentine layer between ganoin and bone that is characteristic of actinopterygians below the halecostome level. The Semionotidae placed at the base of the Halecostomi, exhibit scale histology transitional between the palaeoniscoid and lepidosteoid scale type. Introduction Actinopterygians, from primitive Coccolepididae to advanced teleosts, are represented in the Solnhofen lithographic limestone. These are fishes with rhombic and round scales. Ganoid scales of the lepidosteoid type are found in the following fishes: semionotid Lepidotes and Heterostrophus, macrosemiids Histionotus, Macrosemius, Notagogus and Propterus, ophiopsid Ophiopsis, caturids Furo and Brachyichthys, aspido- rhynchid Belonostomus, pleuropholid Pleuropholis, and pholidophorid Pholidophorus. -

GEOLOGICAL SURVEY OF OHIO. VOL. I.—PART II. PALÆONTOLOGY. SECTION II. DESCRIPTIONS OF FOSSIL FISHES. BY J. S. NEWBERRY. Digital version copyrighted ©2012 by Don Chesnut. THE CLASSIFICATION AND GEOLOGICAL DISTRIBUTION OF OUR FOSSIL FISHES. So little is generally known in regard to American fossil fishes, that I have thought the notes which I now give upon some of them would be more interesting and intelligible if those into whose hands they will fall could have a more comprehensive view of this branch of palæontology than they afford. I shall therefore preface the descriptions which follow with a few words on the geological distribution of our Palæozoic fishes, and on the relations which they sustain to fossil forms found in other countries, and to living fishes. This seems the more necessary, as no summary of what is known of our fossil fishes has ever been given, and the literature of the subject is so scattered through scientific journals and the proceedings of learned societies, as to be practically inaccessible to most of those who will be readers of this report. I. THE ZOOLOGICAL RELATIONS OF OUR FOSSIL FISHES. To the common observer, the class of Fishes seems to be well defined and quite distin ct from all the other groups o f vertebrate animals; but the comparative anatomist finds in certain unusual and aberrant forms peculiarities of structure which link the Fishes to the Invertebrates below and Amphibians above, in such a way as to render it difficult, if not impossible, to draw the lines sharply between these great groups. -

However, a vast majority of these Early Cretaceous fossils lack precise geographical and stratigraphic data. The absence of such contextual proxies hinders our understanding of the apparent variations in faunal composition and abundance patterns across the Araripe Basin. We conducted controlled excavations in the Romualdo Member in order to provide a detailed account of its main stratigraphic, sedimentological and palaeontological features near Santana do Cariri, Ceara´ State. We provide the first fine-scale stratigraphic sequence ever established for the Romualdo Member and we distinguish at least seven concretion-bearing horizons. Notably, a 60-cm-thick group of layers (bMatraca˜oQ), located in the middle part of the member, is virtually barren of fossiliferous concretions. -

Critical review of the Colobodontidae reveals that this family has important research value. Furthermore, the family Perleididae Brough, 1931 and the probably paraphyletic ‘Perleidus group’ Gardiner & Schaeffer, 1989 have been implicitly regarded a synonym of the unsatisfactorily defined family Colobodontidae. Until 2002, Colobodontidae had been universally accepted as a significant taxon among all Triassic ichthyolite. However, the most colobodontids are probably confined to the Anisian and Ladinian in the Western Tethys. A well-preserved colobodontid discovered in Guizhou, South China, throws new light on its distribution and stratigraphic range. Methods A specimen was collected at the Wusha village of Xingyi City, Guizhou Province, South China and is preserved in the Geological Museum of Guizhou Province. The repair work was completed in a physical way in the laboratory of the Department of Geology, Guizhou University. Photographing the specimen was done by a 3D Microscope VHX-100k and drawings were made with reference to the digital photographs.

Ecca Group) of South Africa: a Preliminary Review of Palaeoniscoid Fishes and Taphonomy
Records of the Western Australian Museum Supplement No. 57: 175-181 (1999). The Permian Whitehill Formation (Ecca Group) of South Africa: a preliminary review of palaeoniscoid fishes and taphonomy Fiona J. Evans 1 and Patrick A. Bender2 I Department of Zoology, University of Stellenbosch, Private Bag Xl, Matieland, 7602, South Africa; email: [email protected] 2 Museum of the Council for Geoscience, Private Bag Xl12, Pretoria, 0001, South Africa Abstract - The Permian (Artinskian) Whitehill Formation (Ecca Group) in South Africa and southern Namibia was deposited as part of a large stratified inland sea which extended from the southern margins of South Africa, and southern Namibia, northern Namibia (Aba-Huab Formation, Huab Basin) to the Iratl Formation of the Parana Basin in Brazil and parts of Uruguay. A common biota exists between these two continents, namely mesosaurid reptiles, pygocephalomorph crustacea, wood, palaeoniscoid fish and insects. The Whitehill Formation also contains plant stem fragments, palynomorphs, coprolites, a cephalochordate, rare sponge spicules and traces of arthropods and fish. The good preservation, particularly of the palaeoniscoid material, from the Whitehill Formation contrasts strongly with the disarticulated scales and spines from northern Namibia and Brazil. Recent collections in the Whitehill Formation near Calvinia and Louriesfontein (Northern Cape Province) of South Africa have demonstrated the necessity for a review of the palaeoniscoid taxa present in these units. Possible new species have also been collected, including a deep-bodied form. INTRODUCTION The extensive stratified inland sea in which the Whitehill Formation (Ecca Group, Karoo Supergroup; - - - - - Waterford Fm Figure 1) was deposited had limited or no access to ------------ the ocean according to reconstructions by Oelofsen Fort Brown Fm and Araujo (1987) and Pickford (1995).
