New described species/Taxonomic News:


WELTON, B.J. (2015):
A New Species of Late Early Miocene Cetorhinus(Lamniformes: Cetorhinidae) from the Astoria Formation of Oregon, and Coeval Cetorhinus from Washington and California. Contributions in Science, 523:  67–89
New species: Cetorhinus piersoni
Abstract: Microphagous lamniforms of the family Cetorhinidae have a significant Cenozoic history in the North Pacific Ocean. The Late Eocene Keasius taylori occurs in the Keasey Formation of Oregon, and K. parvus may occur in the Oligocene Lincoln Creek Formation of southwestern Washington. The genus Cetorhinus has one extant species, C. maximus, and a fossil record, including the Middle Miocene C. huddlestonifrom the middle Round Mountain Silt, Sharktooth Hill Bonebed, California, and C. maximus from the Late Miocene through Pleistocene of Oregon and California. An intermediate-sized cetorhinid, Cetorhinus piersoni, new species, is named on teeth from the late Early Miocene Astoria Formation from Lincoln County, Oregon, and coeval deposits of the lower Round Mountain Silt from the southeast part of California’s San Joaquin Valley. Teeth of C. piersoni from California, but not Oregon, occur in association with very small teeth of an as yet undescribed species of Keasius. The type series of C. piersoni is morphologically diverse, although, many of the adult teeth have low, broadly triangular crowns, large roots, and well-developed root lobes reminiscent of the genus Alopias. Cetorhinus piersoni may have had a wider range in diet than C. maximus, feeding on small fishes as well as plankton. Calcified vertebrae of a small basking shark from a late Early Miocene section of the Astoria Formation in southwestern Washington are described and referred to the genus Cetorhinus. These vertebrae differ from those of Keasius in being anteroposteriorly elongated, and in having intermedialia with well-developed perforated concentric lamellae and no calcified radii extending outward from the primary double cone or peripheral to the outermost concentric lamellae. The vertebrae come from marine deposits coeval with the Oregon Astoria Formation type locality of C. piersoni, but without associated teeth, a specific taxonomic assignment is not possible. The depositional environments represented by the Astoria Formation in Washington and Oregon, and the Round Mountain Silt in California, indicate that Cetorhinus piersoni, and C. huddlestoni were warm-water nektopelagic feeders over both deep and shallow waters of the continental shelf.

SHIMADA, K. & POPOV, E.V. & SIVERSSON, M. & WELTON, B.J. & LONG, D.L. (2015): A new clade of putative plankton-feeding sharks from the Upper Cretaceous of Russia and the United States. Journal of Vertebrate Paleontology, in press
New subfamily: Johnlonginae
New genus: Pseudomegachasma
Abstract: Eorhincodon casei from Russia and Megachasma comanchensis from the United States are two Cretaceous taxa initially described as putative planktivorous elasmobranchs, but the type specimens of these two taxa were subsequently reinterpreted to represent taphonomically abraded teeth of an odontaspidid, JohnlongiaSiverson (Lamniformes: Odontaspididae). Here, we redescribe the type materials of ‘E. casei’ and ‘M. comanchensis’ and describe additional specimens of these species from other Late Cretaceous localities in Russia and the United States. These specimens demonstrate that (1) the two fossil taxa are valid species; (2) they warrant the establishment of a new genus of presumed planktivorous sharks,Pseudomegachasma, gen. nov., to accommodate the two species; and (3) the new genus is sister to Johnlongia and together constitute a new subfamily Johnlonginae, subfam. nov., tentatively placed in the family Odontaspididae sensu stricto. This taxonomic placement indicates that the putative planktivorous clade was derived from a presumed piscivorous form (Johnlongia), with an implication thatPseudomegachasma, gen. nov., evolved a plankton-eating habit independent of the four known planktivorous elasmobranch clades (Rhincodontidae, Megachasmidae, Cetorhinidae, and Mobulidae). It also indicates that planktivorous diets evolved independently at least three times in the order Lamniformes (i.e., Megachasmidae, Cetorhinidae, and Odontaspididae), and more significantly, Pseudomegachasma, gen. nov., would represent the oldest known plankton-feeding elasmobranch in the fossil record. The present fossil record suggests that Pseudomegachasma, gen. nov., evolved in a relatively shallow-water environment in Russia in the early Cenomanian or earlier and subsequently migrated to the North American Western Interior Seaway by the mid-Cenomanian.


GOUIRIC-CAVALLI, S. & CABRERA, D.A. & CIONE, A.L. & O'GORMAN, J.P. & CORIA, R.A. & FERNÁNDEZ, M. (2015): The first record of the chimaeroid genusEdaphodon (Chondrichthyes, Holocephali) from Antarctica (Snow Hill Island Formation, Late Cretaceous, James Ross Island). Journal of Vertebrate Paleontology, in press
New genus: Edaphodon snowhillensis
Abstract: A new species of an edaphodontid holocephalian, Edaphodon snowhillensis, sp. nov., is described based on a complete dentition collected in the late Campanian Herbert Sound Member of the Snow Hill Island Formation of James Ross Island, Antarctica. The dentition consists of paired vomerine, mandibular, and palatine tooth plates, which are almost completely preserved. The new species is characterized by a unique character combination out of which the presence of a subquadrangular vomerine tooth plate and a horse-hoof-shaped anterior outer tritor in the mandibular tooth plates appear to be unique characters among the edaphodontids. Edaphodon snowhillensis, sp. nov., represents the most complete dentition of a holocephalian fish from the Southern Hemisphere and the earliest record of the genus Edaphodon from the Antarctic continent and the Weddellian Biogeographic Province. Also, E. snowhillensis, sp. nov., is the southernmost specimen of this genus and according to the size of the tooth plates is one of the largest chimaeroid fish known.


Bythaelurus tenuicephalusn. sp., a new deep-water catshark (Carcharhiniformes, Scyliorhinidae) from the western Indian Ocean. Zootaxa, 4013 (1): 120–138
New genus: Bythaelurus tenuicephalus
Abstract: A new dwarf deep-water catshark, Bythaelurus tenuicephalus, is described based on one adult and one juvenile male specimen from off Tanzania and Mozambique in the western Indian Ocean. The new species differs from its congeners by its slender head and snout, which is only slightly bell-shaped in dorsoventral view without distinct lateral indention. All other Bythaelurus species have distinctly bell-shaped snouts with a strong lateral indention anterior to outer nostrils. Compared to its congeners in the western Indian Ocean, B. tenuicephalus n. sp. also has broader claspers in adult males (base width 2.1% TL vs. 1.5–1.8% TL). It further differs from B. clevai by attaining a smaller maximum size and having a color pattern of fewer and smaller blotches, larger oral papillae, a shorter snout, and broader claspers without knob-like apex and with a smaller envelope and a subtriangular (vs. subrectangular) exorhipidion. Compared to B. hispidus, the new species has a longer snout, a longer dorsal-caudal space, broader clasper without knob-like apex, and fewer vertebral centra. In contrast to B. lutarius, B. tenuicephalus attains a smaller maximum size and has a blotched (vs. largely plain) coloration, numerous (vs. lacking) oral papillae, shorter anterior nasal flaps, a longer caudal fin, a shorter pelvic anal space, and shorter and broader claspers.
