The Shark-Toothed Dolphin Squalodon Cetacea
Carnets Geol. 20 (2) E-ISSN 1634-0744 DOI 10.4267/2042/70716 The shark-toothed dolphin Squalodon (Cetacea: Odontoceti) from the remarkable Montagna della Majella marine vertebrate assemblage (Bolognano Formation, central Italy) Alberto COLLARETA 1 Andrea DI CENCIO 2 Renato RICCI 3 Giovanni BIANUCCI 4 Abstract: The extinct family Squalodontidae consists of heterodont, medium-sized odontocetes, featu- ring a long rostrum that houses large, procumbent incisors and heavily ornamented postcanine teeth carrying accessory denticles, hence their vernacular name, "shark-toothed dolphins". These longirostri- ne toothed whales are often seen as bridging the anatomical gap between archaic Oligocene odontoce- tes and their late Miocene to Holocene relatives. Possibly among the major marine predators of their ti- me, the shark-toothed dolphins are important components of several lower Miocene marine-mammal assemblages from the North Atlantic and Mediterranean/Paratethysian realms. In the present work, a partial skull of Squalodontidae is described from the strata of the Bolognano Formation cropping out in the northeastern sector of the Montagna della Majella massif (Abruzzo, central Italy), which has pre- viously yielded a rich lower Miocene marine-vertebrate assemblage, including eleven taxa of elasmo- branchs as well as subordinate teleosts and very fragmentary remains of marine reptiles and mam- mals. The specimen consists of the anterodorsal portion of a rostrum, preserving parts of both pre- maxillae and left maxilla, and the anteriormost seven upper left teeth. This partial skull is here identi- fied as belonging to the genus Squalodon, whose presence in the Montagna della Majella vertebrate assemblage had already been tentatively proposed on the basis of two fragmentary teeth. -
Cetacea: Phocoenidae) from the Upper Part of the Horokaoshirarika Formation (Lower Pliocene), Numata Town, Hokkaido, Japan, and Its Phylogenetic Position
Palaeontologia Electronica palaeo-electronica.org A new skull of the fossil porpoise Numataphocoena yamashitai (Cetacea: Phocoenidae) from the upper part of the Horokaoshirarika Formation (lower Pliocene), Numata Town, Hokkaido, Japan, and its phylogenetic position Yoshihiro Tanaka and Hiroto Ichishima ABSTRACT An early Pliocene porpoise, Numataphocoena yamashitai from Hokkaido, Japan, is known from the holotype, a fairly well-preserved skeleton with an incomplete skull and a referred earbone. A new skull referred to Numataphocoena yamashitai found from almost the same locality as the holotype is interesting because it expands knowl- edge of skull morphology and improves the diagnosis of this taxon. Numataphocoena yamashitai differs from other phocoenids in having the characteristic feature in the maxilla associated with the posterior dorsal infraorbital foramen, narrower and sharper anterior part of the internal acoustic meatus, and a robust anterior process of the peri- otic. A new cladistic analysis places Numataphocoena yamashitai adjacent to Haboro- phocoena toyoshimai and Haborophocoena minutus, among a clade of early branching phocoenids, all of which are chronologically and geographically close to each other. The new skull is probably a younger individual because it is about 80% the size of that of the holotype and it shows closed but unfused sutures. Our description of this specimen helps to understand the intraspecies variation of the extinct species Numataphocoena yamashitai. Yoshihiro Tanaka.

DESCRIPTION OF TWO SQUALODONTS RECENTLY DIS- COVERED IN THE CALVERT CLIFFS, ^LVRYLAND; AND NOTES ON THE SHARK-TOOTHED CETACEANS. By Remington Kellogg, Of the Bureau of Biological Survey, United States Departynent of Agriculture. INTRODUCTION. When the study of paleontology was less advanced than it is at present, any announcement of the discovery of prehistoric animals unlike the living indigenous fauna was usually received with some suspicion. In spite of this distrust, many attempts were made by the early writers to explain the presence of fossil remains of marine mammals in strata above the sea level or at some distance from the seashore. In one of these treatises ' is found what is, apparently, the first notice of the occurrence of fossil remains referable to shark- toothed cetaceans. The author of this work figures a fragment of a mandible, obtained from the tufa of Malta, which possesses three serrate double-rooted molar teeth. Squalodonts as such were first brought to the attention of ]mleon- tologists in 1840, by J. P. S. Grateloup, ' a French naturalist primarily interested in marine invertebrates. In the original description of Squalodon, Grateloup held the view that this rostral fragment from Leognan, France, belonged to some large saurian related to Iguanodon. Following the anouncement of this discovery. Von Meyer ^ called at- tention to the teeth of this fossil, and concluded that the specimen was referable to some flesh-eating cetacean. A year later, Grateloup* concurred in this opinion. One other specimen should be mentioned in this connection, but, unfortunately, its relationships are quite uncer- tain. This specimen consists of a single tooth which was thought to bear resemblance to some pinniped by Von Meyer ^ and named Pachy- odon mirahilis. -

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. -

Geodiversitas 37 (1): 79-108. http://dx.doi.org/10.5252/g2015n1a4 ABSTRACT Apart from a few exceptions, extant odontocetes (toothed cetaceans) exhibit a roughly homodont dentition. e transition from basilosaurid-like double-rooted cheek teeth with accessory denticles to single-rooted conical teeth occurred during the late Oligocene-early Miocene. At that time, several clades of now extinct, homodont and predominantly long-snouted odontocetes appeared in the fossil record. Among them, members of the genera Argyrocetus Lydekker, 1893 and Macrodelphinus Wilson, 1935, from the early Miocene of the Northeast Pacific and Argentina, were tentatively attributed to the family Eurhinodelphinidae. However, due to the frag- mentary state of the specimens, unambiguous apomorphies of the family could not be detected. -

Uhen3 1 Emory University 2 Duke University 3 Cranbrook Institute of Science KEYWORDS cetacean, encephalization, odontocetes ABSTRACT Toothed whales (order Cetacea: suborder Odontoceti) are highly encephalized, possessing brains that are significantly larger than expected for their body sizes. In particular, the odontocete superfamily Delphinoidea (dolphins, porpoises, belugas, and narwhals) comprises numerous species with encephalization levels second only to modern humans and greater than all other mammals. Odontocetes have also demonstrated behavioral faculties previously only ascribed to humans and, to some extent, other great apes. How did the large brains of odontocetes evolve? To begin to investigate this question, we quantified and averaged estimates of brain and body size for 36 fossil cetacean species using computed tomography and analyzed these data along with those for modern odontocetes.
