Annotated Checklist of Fossil Fishes from the Smoky Hill Chalk of the Niobrara Chalk (Upper Cretaceous) in Kansas
Lucas, S. G. and Sullivan, R.M., eds., 2006, Late Cretaceous vertebrates from the Western Interior. 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. -

The shark fauna of the Upper Cretaceous Hinoshima Formation (Santonian: 86.3–83.6 Ma) of the manuscriptHimenoura Group (Kamiamakusa, Kumamoto Prefecture, Kyushu, Japan) was investigated based on fossil shark teeth found at five localities: Himedo Park, Kugushima, Wadanohana, Higashiura, and Kotorigoe. A detailed geological survey and taxonomic analysis was undertaken, and the habitat, depositional environment, and associated mollusks of each locality were considered in the context of previous studies. Twenty-one species, 15 genera, 11 families, and 6 orders of fossil sharks are recognized from the localities. This assemblage is more diverse than has previously been reported for Japan, and Lamniformes and Hexanchiformes were abundant. Three categories of shark fauna are recognized: a coastal region (Himedo Park; probably a breeding site), the coast to the open sea (Kugushima and Wadanohana), and bottom-dwelling or near-seafloor fauna (Kugushima, Wadanohana, Higashiura, and Kotorigoe). -

Steller Moss Landing Marine Laboratories Dr. Michael H. Graham Moss Landing Marine Laboratories Dr. Scott L. Hamilton Moss Landing Marine Laboratories ABSTRACT COMMUNITY STRUCTURE AND ENERGY FLOW WITHIN RHODOLITH HABITATS AT SANTA CATALINA ISLAND, CA by Scott Stanley Gabara The purpose of this study was to describe the floral and faunal community associated with rhodolith beds, which are aggregations of free-living coralline algal nodules, off of Santa Catalina Island. Surveys of macroalgal cover, infaunal and epifaunal invertebrates, and fishes suggest rhodolith beds off Santa Catalina Island support greater floral and faunal abundances than adjacent sand habitat. Community separation between rhodolith and sand habitats was due to increased presence of fleshy macroalgae, herbivorous gastropods, and greater abundance of infaunal invertebrates dominated by amphipods, mainly tanaids and gammarids. Stable isotopes were used to determine important sources of primary production supporting rhodolith beds and to identify the major pathways of energy. Stable isotopes suggest the rhodolith bed food web is detrital based with contributions from water column particulate organic matter, drift kelp tissue, and kelp particulates from adjacent kelp beds. -

Endangered Species
FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

Upper Cretaceous Chondrichthyes Teeth Record in Phosphorites of the Loma Gorda Formation•
BOLETIN DE CIENCIAS DE LA TIERRA http://www.revistas.unal.edu.co/index.php/rbct Upper Cretaceous chondrichthyes teeth record in phosphorites of the • Loma Gorda formation Alejandro Niño-Garcia, Juan Diego Parra-Mosquera & Peter Anthony Macias-Villarraga Departamento de Geociencias, Facultad de Ciencias Naturales y Exactas, Universidad de Caldas, Manizales, Colombia. [email protected], [email protected], [email protected] Received: April 26th, 2019. Received in revised form: May 17th, 2019. Accepted: June 04th, 2019. Abstract In layers of phosphorites and gray calcareous mudstones of the Loma Gorda Formation, in the vicinity of the municipal seat of Yaguará in Huila department, Colombia, were found fossils teeth of chondrichthyes, these were extracted from the rocks by mechanical means, to be compared with the species in the bibliography in order to indentify them. The species were: Ptychodus mortoni (order Hybodontiformes), were found, Squalicorax falcatus and Cretodus crassidens (order Lamniformes). This finding constitutes the first record of these species in the Colombian territory; which allows to extend its paleogeographic distribution to the northern region of South America, which until now was limited to Africa, Europe, Asia and North America, except for the Ptychodus mortoni that has been described before in Venezuela. Keywords: first record; sharks; upper Cretaceous; fossil teeth; Colombia.
