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. -

Oldest Mephitine Cranium and Its Implications for the Origin of Skunks
Oldest mephitine cranium and its implications for the origin of skunks MIECZYSEAW WOLSAN Wolsan, M. 1999. Oldest mephitine cranium and its implications for the origin of skunks. -Acta Palaeontologica Polonica 44,2,223-230. -- Recent molecular studies have recognized the skunks (Mephitinae) to be the sister taxon of a clade comprising the Procyonidae and Mustelidae. These findings are inconsistent with the traditional placement of the skunks among mustelids, which is based on mor- phological evidence from extant taxa. This paper reports on a well-preserved cranium of a young individual, recovered from the middle Miocene deposits (MN 7+8, about 11-12 Ma) of Steinheim am Albuch, Germany. The fossil is the holotype of Palaeo- mephitis steinheimensis Jager, 1839, which is here recognized as a senior subjective syn- onym of Trochotherium cyamoides Fraas, 1870 (consequently, Palaeomephitis Jager, 1839 is a senior subjective synonym of Trochotherium Fraas, 1870). The specimen is identified as the oldest and most primitive mephitine cranium known to date, approach- ing the primitive morphology for the Mephitinae. It exhibits a combination of mephitine (accessory middle-ear chamber, lateral swelling of the squamosal) and mustelid (mus- telid suprameatal fossa) synapomorphies,corroborating the view that skunks are derived from a mustelid ancestor. Its auditory bulla shows a slightly inflated and relatively large caudal entotympanic, which indicates that the uninflated and relatively small caudal entotympanics of adult mephitines, as well as their hypertrophied ectotympanics, are not primitive (as hitherto assumed) but derived, providing a synapomorphy that supports a sister-group relationship between the Mephitinae and Lutrinae. Key words : Palaeomephitis, Trochotherium,Mephitinae, Mustelidae, Carnivora, phy- logeny, taxonomy, morphology. -

The Taxonomic and Evolutionary History of Fossil and Modern Balaenopteroid Mysticetes
Journal of Mammalian Evolution, Vol. 12, Nos. 1/2, June 2005 (C 2005) DOI: 10.1007/s10914-005-6944-3 The Taxonomic and Evolutionary History of Fossil and Modern Balaenopteroid Mysticetes Thomas A. Demer´ e,´ 1,4 Annalisa Berta,2 and Michael R. McGowen2,3 Balaenopteroids (Balaenopteridae + Eschrichtiidae) are a diverse lineage of living mysticetes, with seven to ten species divided between three genera (Megaptera, Balaenoptera and Eschrichtius). Extant members of the Balaenopteridae (Balaenoptera and Megaptera) are characterized by their engulfment feeding behavior, which is associated with a number of unique cranial, mandibular, and soft anatomical characters. The Eschrichtiidae employ suction feeding, which is associated with arched rostra and short, coarse baleen. The recognition of these and other characters in fossil balaenopteroids, when viewed in a phylogenetic framework, provides a means for assessing the evolutionary history of this clade, including its origin and diversification. The earliest fossil balaenopterids include incomplete crania from the early late Miocene (7–10 Ma) of the North Pacific Ocean Basin. Our preliminary phylogenetic results indicate that the basal taxon, “Megaptera” miocaena should be reassigned to a new genus based on its possession of primitive and derived characters. The late late Miocene (5–7 Ma) balaenopterid record, except for Parabalaenoptera baulinensis and Balaenoptera siberi, is largely undescribed and consists of fossil specimens from the North and South Pacific and North Atlantic Ocean basins. The Pliocene record (2–5 Ma) is very diverse and consists of numerous named, but problematic, taxa from Italy and Belgium, as well as unnamed taxa from the North and South Pacific and eastern North Atlantic Ocean basins. -

Terry Chesser, Helen F. James, Max A. Levy, Joan Ferrer Obiol, Vincent Bretagnolle, Jacob González-Solís, Andreanna J. Welch This pdf file includes: Supplementary Information Text Figures S1-S7 SUPPLEMENTARY INFORMATION TEXT Fossil calibrations The fossil record of Procellariiformes is sparse when compared with other bird orders, especially its sister order Sphenisciformes (Ksepka & Clarke 2010, Olson 1985c). There are, however, some fossil Procellariiformes that are both robustly dated and identified and therefore suitable for fossil calibrations. Our justification of these fossils, below, follows best practices described by Parham et al. (2012) where possible. For all calibration points only a minimum age was set with no upper constraint specified, except for the root of the tree. 1. Node between Sphenisciformes/Procellariiformes Minimum age: 60.5 Ma Maximum age: 61.5 Ma Taxon and specimen: Waimanu manneringi (Slack et al. 2006); CM zfa35 (Canterbury Museum, Christchurch, New Zealand), holotype comprising thoracic vertebrae, caudal vertebrae, pelvis, femur, tibiotarsus, and tarsometatarsus. Locality: Basal Waipara Greensand, Waipara River, New Zealand. Phylogenetic justification: Waimanu has been resolved as the basal penguin taxon using morphological data (Slack et al. 2006), as well as combined morphological and molecular datasets (Ksepka et al. 2006, Clarke et al. 2007). Morphological and molecular phylogenies agree on the monophyly of Sphenisciformes and Procellariiformes (Livezey & Zusi 2007, Prum et al. 2015). Waimanu manneringi was previously used by Prum et al. (2015) to calibrate Sphenisiciformes, and see Ksepka & Clarke (2015) for a review of the utility of this fossil as a robust calibration point. -
Appendix G Paleontological Resources Assessment
Appendix G Paleontological Resources Assessment Paleontological Resource Assessment for the California Flats Solar Project, Monterey and San Luis Obispo Counties, California Jessica L. DeBusk Prepared By Applied EarthWorks, Inc. 743 Pacific Street, Suite A San Luis Obispo, CA 93401 Prepared For Element Power US, LLC 421 SW Sixth Avenue, Suite 1000 Portland, OR 97204 April 2013 draft SUMMARY OF FINDINGS At the request of Element Power US, LLC, parent company of California Flats Solar, LLC (the Applicant), Applied EarthWorks Inc. (Æ) performed a paleontological resource assessment for the California Flats Solar Project (Project) located southeast of Parkfield in Monterey and San Luis Obispo counties, California. The study consisted of a museum records search, a comprehensive literature and geologic map review, and a field survey. This report summarizes the methods and results of the paleontological resource assessment and provides Project-specific management recommendations. This assessment included a comprehensive review of published and unpublished literature and museum collections records maintained by the Natural History Museum of Los Angeles County (LACM) and the University of California Museum of Paleontology (UCMP). The purpose of the literature review and museum records search was to identify the geologic units underlying the Project area and to determine whether or not previously recorded paleontological localities occur either within the Project boundaries or within the same geologic units elsewhere. The museum records search was followed by a field survey. The purpose of the field survey was to visually inspect the ground surface for exposed fossils and to evaluate geologic exposures for their potential to contain preserved fossil material at the subsurface. -
