Pyenson1,2, Jorge Velez-Juarbe´ 3,4, Carolina S. Gutstein1,5, Holly Little1, Dioselina Vigil6 and Aaron O’Dea6 1 Department of Paleobiology, National Museum of Natural History, Smithsonian Institution, Washington, DC, USA 2 Departments of Mammalogy and Paleontology, Burke Museum of Natural History and Culture, Seattle, WA, USA 3 Department of Mammalogy, Natural History Museum of Los Angeles County, Los Angeles, CA, USA 4 Florida Museum of Natural History, University of Florida, Gainesville, FL, USA 5 Comision´ de Patrimonio Natural, Consejo de Monumentos Nacionales, Santiago, Chile 6 Smithsonian Tropical Research Institute, Balboa, Republic of Panama ABSTRACT In contrast to dominant mode of ecological transition in the evolution of marine mammals, different lineages of toothed whales (Odontoceti) have repeatedly invaded freshwater ecosystems during the Cenozoic era. The so-called ‘river dolphins’ are now recognized as independent lineages that converged on similar morphological specializations (e.g., longirostry). In South America, the two endemic ‘river dolphin’ lineages form a clade (Inioidea), with closely related fossil inioids from marine rock units in the South Pacific and North Atlantic oceans. Here we describe a new genus and species of fossil inioid, Isthminia panamensis, gen. et sp. nov. from the late Miocene of Panama. The type and only known specimen consists of a partial skull, mandibles, isolated teeth, a right scapula, and carpal elements recovered from Submitted 27 April 2015 the Pina˜ Facies of the Chagres Formation, along the Caribbean coast of Panama. -

En el presente trabajo se reestudian las especies previamente descriptas, y se describen varios nuevos taxones. El estudio se ha dividido en especies procedentes de sedimentitas marinas informalmente agrupadas bajo el nombre de "Entrerriense", y aquellas especies procedentes de aguas continentales, de sedimentitas agrupadas en el Piso/Edad Mesopotamiense, por primera vez propuesto aquí de manera formal. Dentro de las especies procedentes de sedimentitas marinas se han reconocido dos asociaciones consideradas diacrónicas. Las más antigua, referida · al Mioceno medio, procede de los afloramientos del ·"Entrerriense" de Patagonia, agrupandó seis especies, en su mayoría descriptas aquí por primera vez: Patagophyseter rionegrensis (Gondar) nueva combinación (Cetacea, Physeteridae); Notoziphius bruneti gen. y esp. nuevos (Cetacea, Ziphiidae); Goos valdesensis gen. y esp. nuevos (Cetacea, Balenidae); "Plesiocetus" notopelagicus Cabrera, 1926 (Cetacea, Cetotheriidae); Kawas benegasii gen. -
Smithsonian Contributions to Paleobiology • Number 90
SMITHSONIAN CONTRIBUTIONS TO PALEOBIOLOGY • NUMBER 90 Geology and Paleontology of the Lee Creek Mine, North Carolina, III Clayton E. Ray and David J. Bohaska EDITORS ISSUED MAY 112001 SMITHSONIAN INSTITUTION Smithsonian Institution Press Washington, D.C. 2001 ABSTRACT Ray, Clayton E., and David J. Bohaska, editors. Geology and Paleontology of the Lee Creek Mine, North Carolina, III. Smithsonian Contributions to Paleobiology, number 90, 365 pages, 127 figures, 45 plates, 32 tables, 2001.—This volume on the geology and paleontology of the Lee Creek Mine is the third of four to be dedicated to the late Remington Kellogg. It includes a prodromus and six papers on nonmammalian vertebrate paleontology. The prodromus con tinues the historical theme of the introductions to volumes I and II, reviewing and resuscitat ing additional early reports of Atlantic Coastal Plain fossils. Harry L. Fierstine identifies five species of the billfish family Istiophoridae from some 500 bones collected in the Yorktown Formation. These include the only record of Makairapurdyi Fierstine, the first fossil record of the genus Tetrapturus, specifically T. albidus Poey, the second fossil record of Istiophorus platypterus (Shaw and Nodder) and Makaira indica (Cuvier), and the first fossil record of/. platypterus, M. indica, M. nigricans Lacepede, and T. albidus from fossil deposits bordering the Atlantic Ocean. Robert W. Purdy and five coauthors identify 104 taxa from 52 families of cartilaginous and bony fishes from the Pungo River and Yorktown formations. The 10 teleosts and 44 selachians from the Pungo River Formation indicate correlation with the Burdigalian and Langhian stages. The 37 cartilaginous and 40 bony fishes, mostly from the Sunken Meadow member of the Yorktown Formation, are compatible with assignment to the early Pliocene planktonic foraminiferal zones N18 or N19. -
The Biology of Marine Mammals
Romero, A. 2009. The Biology of Marine Mammals. The Biology of Marine Mammals Aldemaro Romero, Ph.D. Arkansas State University Jonesboro, AR 2009 2 INTRODUCTION Dear students, 3 Chapter 1 Introduction to Marine Mammals 1.1. Overture Humans have always been fascinated with marine mammals. These creatures have been the basis of mythical tales since Antiquity. For centuries naturalists classified them as fish. Today they are symbols of the environmental movement as well as the source of heated controversies: whether we are dealing with the clubbing pub seals in the Arctic or whaling by industrialized nations, marine mammals continue to be a hot issue in science, politics, economics, and ethics. But if we want to better understand these issues, we need to learn more about marine mammal biology. The problem is that, despite increased research efforts, only in the last two decades we have made significant progress in learning about these creatures. And yet, that knowledge is largely limited to a handful of species because they are either relatively easy to observe in nature or because they can be studied in captivity. Still, because of television documentaries, ‘coffee-table’ books, displays in many aquaria around the world, and a growing whale and dolphin watching industry, people believe that they have a certain familiarity with many species of marine mammals (for more on the relationship between humans and marine mammals such as whales, see Ellis 1991, Forestell 2002). As late as 2002, a new species of beaked whale was being reported (Delbout et al. 2002), in 2003 a new species of baleen whale was described (Wada et al. -

A New Kentriodontine Dolphin from the Middle Miocene of Portugal
A new kentriodontine dolphin from the middle Miocene of Portugal OLIVIER LAMBERT, MÁRIO ESTEVENS, and RICHARD SMITH Lambert, O., Estevens, M., and Smith, R. 2005. A new kentriodontine dolphin from the middle Miocene of Portugal. Acta Palaeontologica Polonica 50 (2): 239–248. A nearly complete skull, a partial left scapula, five lumbar vertebrae, and some fragments of ribs of a medium−sized kentriodontid dolphin (Cetacea, Odontoceti) discovered in the middle Miocene of Setúbal Peninsula, Lower Tagus Basin, Portugal, are herein assigned to a new genus and species, Tagicetus joneti. Within the grade−level family Kentrio− dontidae, the new taxon is referred to the specifically and ecologically diversified subfamily Kentriodontinae, essentially defined by a well−developed posterolateral projection of the nasal. The elongated rostrum, the constriction of the asym− metric premaxillae at the base of the rostrum, the anteriorly elongated palatines, and the elevated vertex of T. joneti sug− gest closer affinities with the larger, more derived Macrokentriodon morani, from the middle Miocene of Maryland (USA). Among other features, T. joneti differs from the latter in having more numerous maxillary teeth and shorter zygomatic processes of the squamosals. Besides providing additional indications about the evolutionary trends within the Kentriodontinae, this occurrence constitutes the first record of the subfamily from the east coast of the North Atlantic based on a nearly complete skull. Considering their morphological diversity and wide geographic -
Mammalia: Cetacea) from the Chagres Formation of Panama and the Evolution of "River Dolphins" in the Americas
Reviewing Manuscript To avoid issues relating to nomenclatural acts, minor sections of this article which reported on the naming of a new species, and which did not make it into the final publication, have been redacted. a new fossil inioid (Mammalia: Cetacea) from the Chagres Formation of Panama and the evolution of "river dolphins" in the Americas Nicholas D Pyenson, Jorge Velez-Juarbe, Carolina S. Gutstein, Holly Little, Dioselina I Vigil, Aaron O'Dea In contrast to dominant mode of ecological transition in the evolution of marine mammals, different lineages of toothed whales (Odontoceti) have repeatedly invaded freshwater ecosystems during the Cenozoic era. The so-called “river dolphins” are now recognized as independent lineages that converged on similar morphological specializations (e.g., longirostry). In South America, the two endemic “river dolphin” lineages form a clade (Inioidea), with closely related fossil inioids from marine rock units in the South Pacific and North Atlantic Oceans. Here we describe a new species of fossil inioid, nov. gen., nov. sp., from the late Miocene of Panama. The type and only known specimen consists of a partial skull, mandibles, isolated teeth, and a right scapula recovered from the Piña facies of the Chagres Formation, along the Caribbean coast of Panama. Sedimentological and associated fauna from the Piña facies point to fully marine conditions with high planktonic productivity 6.8-7.5 million years ago (middle Messinian to earliest Tortonian), which predates final closure of the Isthmus of Panama. Along with ecomorphological data, we propose that was primarily a marine inhabitant, similar to modern oceanic delphinoids. -

Pliocene Marine Mammals from the Whalers Bluff Formation of Portland, Victoria, Australia
Memoirs of Museum Victoria 62(1): 67–89 (2005) ISSN 1447-2546 (Print) 1447-2554 (On-line) http://www.museum.vic.gov.au/memoirs/index.asp Pliocene marine mammals from the Whalers Bluff Formation of Portland, Victoria, Australia ERICH M.G. FITZGERALD School of Geosciences, Monash University, Vic. 3800, Australia and Museum Victoria, G.P.O. Box 666, Melbourne, Vic. 3001, Australia ([email protected]) Abstract Fitzgerald, E.M.G. Pliocene marine mammals from the Whalers Bluff Formation of Portland, Victoria, Australia. Memoirs of Museum Victoria 62(1): 67–89. The most diverse and locally abundant Australian fossil marine mammal assemblages are those from late Neogene (Late Miocene through Late Pliocene) sediments in Victoria and Flinders Island, Tasmania. However, none of these assemblages have hitherto been described. The Pliocene (>2.5–4.8 Ma) Whalers Bluff Formation, exposed in beach cliff sections and offshore reefs, at Portland, western Victoria (38°19'S, 141°38'E) has yielded a small but moderately diverse assemblage of marine mammals represented by fragmentary material. Taxa present include: right whales (Balaenidae); rorqual whales (Balaenopteridae); a physeterid similar to the extant sperm whale (cf. Physeter sp.); the first Australian fossil record of pygmy sperm whales (Kogiidae); at least three genera of dolphins (Delphinidae: cf. Tursiops sp., Delphinus sp. or Stenella sp., and an undetermined genus and species); and probable earless or true seals (Phocidae). This small assemblage represents the first Australian fossil marine mammal assemblage to be described in detail. The taxonomic composition of this Pliocene marine mammal assemblage is generally similar to the present day marine mammal assemblage in north-west Bass Strait.
