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. -

Daget (1964) definiu os ossos da série infraorbital como sendo os ossos que se dispõem ao longo do canal infraorbital (canal que segue da região nasal, passa abaixo das narinas e dos olhos e segue para trás pelo dermopterótico, chegando ao extraescapular e encontrando o canal da linha lateral), à frente do pterótico e anexados à margem da órbita. Expôs que podiam ser designados por número de ordem, da parte mais anterior para a mais posterior (e.g., infraorbital 1, infraorbital 2, infraorbital 3) ou por posição em relação a órbita (e.g., antorbital, suborbital e postorbital). O autor adotou a designação por ordem. Expôs ainda que é comum a denominação do último infraorbial como dermoesfenótico, osso no qual muitas vezes ocorre a anastomose do canal infraorbital com o canal supraorbital (canal que passa no nasal e no frontal). Para os ossos sem canal da série orbital, os quais Daget tratou como puramente membranosos, ele definiu como supraorbitais os ossos anexados ao longo da borda antero-lateral do frontal e como adenasal (= antorbital para outros autores) o osso entre o nasal e o primeiro infraorbital (Daget, 1964: fig. 38). Patterson (1973), da mesma forma que Daget (1964), denominou de infraorbitais os ossos anexados à margem inferior da órbita pelos quais passava o canal infraorbital e de supraorbitais os ossos anexados à margem superior da órbita e ao frontal. -

The topology of the majority rule consensus tree was: (Sardinioides + Hemisaurida + (Nardorex + (Atolvorator + (Protostomias + Yabrudichthys) + (Apateopholis + (Serrilepis + (Halec + Phylactocephalus) + (Cimolichthys + (Prionolepis + ((Eurypholis + Saurorhamphus) + (Enchodus + (Paleolycus + Parenchodus))))))) + ((Ichthyotringa + Apateodus) + (Rharbichthys + (Trachinocephalus + ((Apuliadercetis + Brazilodercetis) + (Benthesikyme + (Cyranichthys + Robertichthys) + (Dercetis + Ophidercetis)) + (Caudadercetis + (Pelargorhynchus + (Nardodercetis + (Rhynchodercetis + (Dercetoides + Hastichthys)))))). The group Enchodontoidei is not monophyletic. Dercetidae form a clade supported by the presence of very reduced neural spines and possess a new composition. Enchodontidae are monophyletic by the presence of middorsal scutes, and Rharbichthys was excluded. Halecidae possess a new composition, with the exclusion of Hemisaurida. This taxon and Nardorex are Aulopiformes incertae sedis. -

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. -

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). -

We present a new record of amiid fish discovered during field works carried out in 2019- 2020 in rocks of the Upper Cretaceous Araçatuba Formation, Western São Paulo State, southeastern Brazil. Although the fish fauna of the Bauru Group is still poorly known, mainly based on isolated remains, the discoveries of amiid remains (including the one here presented) along distinct geological formations and localities and the reinterpretation of previous records bolster it was an abundant group in the continental environments of the Bauru Group during the Late Cretaceous.
