Annotated Checklist of Fossil Fishes from the Smoky Hill Chalk of the Niobrara Chalk (Upper Cretaceous) in Kansas

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). -

Asopcafa was formed in 2013 by 88 coffee growers living in and around the municipality of Aipe. The growers, above all, sought to promote agriculture (in particular, coffee) as a means of human development in the region. Like much of rural Colombia, Huila was heavily affected by the Colombian Armed Conflict of the 1990s and early 2000s. FARC guerrillas took over huge swaths of Northern Nariño and neighbouring Tolima & Cauca, creating a corridor of migration into Huila as families fled FARC control and the ensuing violence. Governmental presence was limited, the FARC had a heavy hand in the local economy, and families and communities had great difficulties making ends meet. -

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). -

Micro-Computed Tomography Imaging Reveals the Development of A
www.nature.com/scientificreports OPEN Micro-computed tomography imaging reveals the development of a unique tooth mineralization pattern Received: 20 February 2019 Accepted: 18 June 2019 in mackerel sharks (Chondrichthyes; Published: xx xx xxxx Lamniformes) in deep time Patrick L. Jambura 1, René Kindlimann2, Faviel López-Romero1, Giuseppe Marramà 1, Cathrin Pfaf 1, Sebastian Stumpf 1, Julia Türtscher1, Charlie J. Underwood 3, David J. Ward 4 & Jürgen Kriwet 1 The cartilaginous fshes (Chondrichthyes) have a rich fossil record which consists mostly of isolated teeth and, therefore, phylogenetic relationships of extinct taxa are mainly resolved based on dental characters. One character, the tooth histology, has been examined since the 19th century, but its implications on the phylogeny of Chondrichthyes is still in debate. We used high resolution micro-CT images and tooth sections of 11 recent and seven extinct lamniform sharks to examine the tooth mineralization processes in this group. Our data showed similarities between lamniform sharks and other taxa (a dentinal core of osteodentine instead of a hollow pulp cavity), but also one feature that has not been known from any other elasmobranch fsh: the absence of orthodentine. Our results suggest that this character resembles a synapomorphic condition for lamniform sharks, with the basking shark, Cetorhinus maximus, representing the only exception and reverted to the plesiomorphic tooth histotype. Additionally, †Palaeocarcharias stromeri, whose afliation still is debated, shares the same tooth histology only known from lamniform sharks. This suggests that †Palaeocarcharias stromeri is member of the order Lamniformes, contradicting recent interpretations and thus, dating the origin of this group back at least into the Middle Jurassic. -

When the “primitive” shark Tribodus (Hybodontiformes) meets the “mod - ern” ray Pseudohypolophus (Rajiformes): the unique co-occurrence of these two durophagous Cretaceous selachians in Charentes (SW France) . Acta Geologica Polonica , 58 (2), 249-255 . Warszawa. The palaeoecology and palaeobiogeography of two Cretaceous selachian genera, Tribodus BRITO & F ERREIRA , 1989 and Pseudohypolophus CAPPETTA & C ASE , 1975 , are briefly discussed. These two similar-sized taxa devel - oped an analogous pavement-like grinding dentition, characterized by massive teeth with a rhomboidal to hexag - onal occlusal surface. Although both genera appear to have been euryhaline forms, the hybodont Tribodus occurred in fresh/brackish water habitats (e.g. deltas) to shallow marine lagoons, whereas the ray Pseudohypolophus lived in brackish water to coastal marine environments. Palaeobiogeographically, their global distribution displays two distinct but adjoined areas, with Tribodus being present in the northern part of Gondwana (Brazil and North Africa), and Pseudohypolophus occurring on both sides of the North Atlantic (North America and Western Europe). How - ever, the two genera coexisted during Cenomanian times within a small overlap zone, localized in western France.
