The fossil sirenian material from the upper Oligocene Linz Sands of Upper Austria is reviewed and re-described in detail following a recent approach on the invalidity of the genus Halitherium Kaup, 1838. This morphological study provides the fi rst evidence for the synonymy of “Halitherium” cristolii Fitzinger 1842, “H.” abeli Spillmann, 1959 and “H.” pergense (Toula, 1899), supporting the hypothesis that only a single species inhabited the late Oligocene shores of present-day Upper Austria.

Geodiversitas 35 (4): 815-940. http://dx.doi.org/g2013n4a5 ABSTRACT e newly discovered Upper Miocene to Upper Pliocene San Gregorio assem- blage of the Purisima Formation in Central California has yielded a diverse collection of 34 marine vertebrate taxa, including eight sharks, two bony fish, three marine birds (described in a previous study), and 21 marine mammals. Pinnipeds include the walrus Dusignathus sp., cf. D. seftoni, the fur seal Cal- lorhinus sp., cf. C. gilmorei, and indeterminate otariid bones. Baleen whales include dwarf mysticetes (Herpetocetus bramblei Whitmore & Barnes, 2008, Herpetocetus sp.), two right whales (cf. Eubalaena sp. 1, cf. Eubalaena sp. 2), at least three balaenopterids (“Balaenoptera” cortesi “var.” portisi Sacco, 1890, cf. Balaenoptera, Balaenopteridae gen. et sp. indet.) and a new species of rorqual (Balaenoptera bertae n. sp.) that exhibits a number of derived features that place it within the genus Balaenoptera. is new species of Balaenoptera is relatively small (estimated 61 cm bizygomatic width) and exhibits a comparatively nar- row vertex, an obliquely (but precipitously) sloping frontal adjacent to vertex, anteriorly directed and short zygomatic processes, and squamosal creases.

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.

    The triple origin of whales DAVID PETERS Independent Researcher 311 Collinsville Avenue, Collinsville, IL 62234, USA [email protected] 314-323-7776 July 13, 2018 RH: PETERS—TRIPLE ORIGIN OF WHALES Keywords: Cetacea, Mysticeti, Odontoceti, Phylogenetic analyis ABSTRACT—Workers presume the traditional whale clade, Cetacea, is monophyletic when they support a hypothesis of relationships for baleen whales (Mysticeti) rooted on stem members of the toothed whale clade (Odontoceti). Here a wider gamut phylogenetic analysis recovers Archaeoceti + Odontoceti far apart from Mysticeti and right whales apart from other mysticetes. The three whale clades had semi-aquatic ancestors with four limbs. The clade Odontoceti arises from a lineage that includes archaeocetids, pakicetids, tenrecs, elephant shrews and anagalids: all predators. The clade Mysticeti arises from a lineage that includes desmostylians, anthracobunids, cambaytheres, hippos and mesonychids: none predators. Right whales are derived from a sister to Desmostylus. Other mysticetes arise from a sister to the RBCM specimen attributed to Behemotops. Basal mysticetes include Caperea (for right whales) and Miocaperea (for all other mysticetes). Cetotheres are not related to aetiocetids. Whales and hippos are not related to artiodactyls. Rather the artiodactyl-type ankle found in basal archaeocetes is also found in the tenrec/odontocete clade. Former mesonychids, Sinonyx and Andrewsarchus, nest close to tenrecs. These are novel observations and hypotheses of mammal interrelationships based on morphology and a wide gamut taxon list that includes relevant taxa that prior studies ignored. Here some taxa are tested together for the first time, so they nest together for the first time. INTRODUCTION Marx and Fordyce (2015) reported the genesis of the baleen whale clade (Mysticeti) extended back to Zygorhiza, Physeter and other toothed whales (Archaeoceti + Odontoceti).

Delegación Coyoacán, México Distrito Federal, 04510. [email protected] ABSTRACT For many years the diversity of dinosaurs of Mexico during the Late Cretaceous has been poorly understood. This is due to the limited taxonomical determinations and the abundant undescribed material. This paper presents a new review of the up-to-date osteological record of Late Cretaceous dinosaurs from Mexico, based on published papers, unpublished data and direct observation of the material housed in Mexican paleonto- logical collections and in the field. Some diagnostic dinosaur bones were taxonomically reassigned and oth- ers reported in the literature were located in collections. We document new localities with dinosaur remains in Fronteras Sonora, Manuel Benavides and Jiménez Chihuahua, General Cepeda and Saltillo Coahuila. Additionally we report new material relating to tyrannosaurids, ornithomimids, ankylosaurs, ceratopsids and hadrosaurids which extends their geographic and temporal distribution in Mexico. This investigation has revealed a dinosaur faunal assemblage consistent with others studies of North American Late Cretaceous fau- nas, abundant large bodied dinosaurs and poorly represented small dinosaurs.

    La Brea and Beyond: The Paleontology of Asphalt-Preserved Biotas Edited by John M. Harris Natural History Museum of Los Angeles County Science Series 42 September 15, 2015 Cover Illustration: Pit 91 in 1915 An asphaltic bone mass in Pit 91 was discovered and exposed by the Los Angeles County Museum of History, Science and Art in the summer of 1915. The Los Angeles County Museum of Natural History resumed excavation at this site in 1969. Retrieval of the “microfossils” from the asphaltic matrix has yielded a wealth of insect, mollusk, and plant remains, more than doubling the number of species recovered by earlier excavations. Today, the current excavation site is 900 square feet in extent, yielding fossils that range in age from about 15,000 to about 42,000 radiocarbon years.

    Second Song for Many (2019)

    second song for many (2019) Tim PARKINSON Sample performance for Not Copyright 2019 © Tim Parkinson second song for many (2019) for any number of instrumentalists (ideally at least 5 to 20) The score consists of 75 bars of 6’ each, in sections listed A-O, for Audio Track, Continuo, and Ensemble with Conductor. A Conductor uses a stopwatch to signal each bar. Audio Track - A 1” beep (f5) every 30”, beginning at the second before 0’00”. The beeps may act as an audio cue for each section (except for the central sections F-J where they continue strictly in 30” intervals). This part may be prerecorded audio track, or may be performed live by one person playing an electronic beep (sine tone or other waveform on a keyboard) using a stopwatch to keep strict time. Continuo - Instrument may be any type of keyboard, (e.g. piano/electric keyboard/accordion/reed organ); or 2 keyboards; or treble clef may be keyboard and bass clef a pair of matching instruments (e.g. 2 clarinets/2 bassoons/2 violas/cellos) Treble clef melody plays quietly, legato and continuously from start to finish. Bass clef chords may be held until the next, or there may be rests in between. For both clefs the rhythm is very approximate, imprecise, irregular. Notation given is approximate number of notes per unit. Meandering, hesitating, for itself. The continuo may be positioned separately from the ensemble, to one side, but not offstage. Ensemble - Texts are given to provide rhythms for tapping on instruments (A-E), with stones (K-O), and for whispering.
