W. 2013. — A new marine vertebrate assemblage from the Late Neogene Purisima Formation in Central California, part II: Pinnipeds and Cetaceans. 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. -

Evidence from the Fossil Record
Chapter 3 LESSON 1 Evidence from the Fossil Record Essential Question Pictures of the Past How are fossils used to learn about the history of To the untrained eye, fossils might look like ordinary rocks. But to a trained scientist, they are much more than that. They paint a picture life on Earth? of past organisms and environments that often look different from current organisms and environments. Warm Up When a Moroccan fossil collector showed scientist Nizar Ibrahim a box What clues about the of fossils, Ibrahim knew one of them was special. Years later he would past can you get from realize just how special it was. In 2014 the fossil collector led Ibrahim a fossil? and his team to the site where the fossil was found. It was in the middle of the Moroccan Sahara Desert. The team unearthed several more fossils. The fossils came from a dinosaur called Spinosaurus. They Vocabulary were about 100 million years old. biodiversity Spinosaurus was a large predatory dinosaur. The first Spinosaurus chordate fossils were discovered by Ernst Stromer in Egypt in 1912, but the fossils were destroyed during World War II. Since that time, Spinosaurus cyanobacteria had eluded scientists. microfossil Ibrahim and his team dug up many Spinosaurus bones. With the help paleontologist of Stromer’s original drawings, they used the bones to reconstruct the Spinosaurus skeleton. The skull was shaped like a crocodile’s, with sharp, cone-shaped teeth. Its back had a structure like a sail on top of it. Its hip bones were narrow. The bones in its feet were shaped like paddles. -
A Century of Spinosaurs - a Review and Revision of the Spinosauridae
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Queen Mary Research Online A century of spinosaurs - a review and revision of the Spinosauridae with comments on their ecology HONE David William Elliott1, * HOLTZ Thomas Richard Jnr2 1 School of Biological and Chemical Sciences, Queen Mary University of London, London, E1 4NS, UK 2 Department of Geology, University of Maryland, College Park, MD 20742 USA Abstract: The spinosaurids represent an enigmatic and highly unusual form of large tetanuran theropods that were first identified in 1915. A recent flurry of discoveries and taxonomic revisions of this important and interesting clade had added greatly to our knowledge, however, spinosaur body fossils are generally rare and most species are known from only limited skeletal remains. Their unusual anatomical adaptations to the skull, limbs and axial column all differ from other large theropods and point to an unusual ecological niche and a lifestyle intimately linked to water. Keywords: Theropoda, Megalosauroidea, Baryonychinae, Spinosaurinae, palaeoecology E-mail: [email protected] 1 Introduction The Spinosauridae is an enigmatic clade of large and carnivorous theropods from the Jurassic and Cretaceous that are known from both Gondwana and Laurasia (Holtz et al., 2004). Despite their wide temporal and geographic distribution, the clade is known primarily from teeth and the body fossil record is extremely limited (Bertin, 2010). As such, relatively little is known about this group of animals, although their unusual morphology with regard to skull shape, dentition, dorsal neural spines and other features mark them out as divergent from the essential bauplan of other non-tetanuran theropods (Fig 1). -

New Discoveries of Fossil Toothed Whales from Peru: Our Changing Perspective of Beaked Whale and Sperm Whale Evolution
Quad. Mus. St. Nat. Livorno, 23: 13-27 (2011) DOI code: 10.4457/musmed.2010.23.13 13 New discoveries of fossil toothed whales from Peru: our changing perspective of beaked whale and sperm whale evolution OLIVIER LAMBERT1 SUMMARY: Following the preliminary description of a first fossil odontocete (toothed whale) from the Miocene of the Pisco Formation, southern coast of Peru, in 1944, many new taxa from Miocene and Pliocene levels of this formation were described during the 80’s and 90’s, (families Kentriodontidae, Odobenocetopsidae, Phocoenidae, and Pontoporiidae). Only one Pliocene Ziphiidae (beaked whale) and one late Miocene Kogiidae (dwarf sperm whale) were defined. Modern beaked whales and sperm whales (Physeteroidea = Kogiidae + Physeteridae) share several ecological features: most are predominantly teuthophagous, suction feeders, and deep divers. They further display a highly modified cranial and mandibular morphology, including tooth reduction in both groups, high vertex and sexually dimorphic mandibular tusks in ziphiids, and development of a vast supracranial basin in physeteroids. New discoveries from the Miocene of the Pisco Formation enrich the fossil record of ziphiids and physeteroids and shed light on various aspects of their evolution. From Cerro Colorado, a new species of the ziphiid Messapicetus lead to the description of features previously unknown in fossil members of the family: association of complete upper and lower tooth series with tusks, hypothetical sexual dimorphism in the development of the tusks, skull anatomy of a calf... A new small ziphiid from Cerro los Quesos, Nazcacetus urbinai, is characterized by the reduction of the dentition: a pair of apical mandibular tusks associated to vestigial postapical teeth, likely hold in the gum. -
Early Evolution of Whales
Early Evolution of Whales A Century of Research in Egypt Philip D. Gingerich Introduction Living whales are fully aquatic and belong to two suborders of Cetacea: Mysticeti (baleen whales) and Odontoceti (toothed whales). Both of these modern suborders appeared when Earth changed from a ‘greenhouse’ earth to an ‘icehouse’ earth at in about the beginning of the Oligocene epoch (Zachos et al., 2001). Early whales, from the ‘greenhouse’ Eocene, all belong to a distinct paraphyletic suborder Archaeoceti. Archaeocetes differ from later modern whales in retaining many characteristics of land mammals, including complexly occluding cheek teeth, ear bones well integrated with the rest of the cranium, longer necks, less specialized forelimb flippers, and hind limbs with feet and toes. Archaeocetes are, in essence, the transitional forms documenting the origin of whales from an earlier land-mammal ancestry (Gingerich, 2005). The first archaeocete fossil to be studied scientifically was a very large vertebral centrum collected in 1832 near the Ouachita River in Caldwell Parish, Louisiana. This measured some 35 cm in length and was but one of a series of 28 vertebrae found together there. The animal represented was named Basilosaurus or ‘king lizard’ because of its size and presumed reptilian heritage (Harlan, 1834). At the time the British anatomist Richard Owen was busy studying the large reptiles he eventually called dinosaurs. To solve the mystery of Basilosaurus, Owen secured additional remains and showed that it was a mammal because its cheek teeth are double-rooted. Owen (1839) deemed the name Basilosaurus to be inappropriate and proposed Zeuglodon or ‘yoked teeth’ as a replacement name. -
