Pliocene pinniped from the San Diego formation of Southern California by Gretchen Mary (Lyon) Burleson Download PDF EPUB FB2

San Diego Formation deposits were formed in a large, open, crescent-shaped bay similar in size to Monterey Bay that existed on the coast in Pliocene times. Aquifer. The formation contains the San Diego Formation Basin, a large aquifer under Imperial Beach, Chula Vista, National City, and southern portions of the city of San Diego.

This sandy to gravelly unit was deposited late in the Pliocene (3–2 Ma) and possibly Pleistocene (> Ma), in settings mostly from shoreface to mid- and outer by: 4.

A new taxon of stem otariid, Eotaria citrica sp. nov., is described from the upper Burdigalian to lower Langhian “Topanga” formation of Orange County, California.

The new species is described from mandibular and dental remains that show a unique combination of plesiomorphic and derived characters. Specifically, it is characterized by having trenchant and prominent paraconid cusps in p3.

Collections from the late Pliocene San Diego Formation of southern California included two new species of walruses - the extremely bizarre toothless Valenictus chulavistensis (which deserves several posts by itself), and the 'bizarrer' Dusignath us seftoni, both described by Tom Demere (a), the curator of SDNHM.

seftoni is known from several crania and jaws, a partial skeleton, and a. Lastly, the youngest of the formations used in this study is the Zanclean to Gelasian San Diego formation (Wagner et al., ; Vendrasco et al., ).

Three pinniped taxa are known from this formation, the crown otariid Callorhinus gilmorei and the odobenids Valenictus chulavistensis Deméré,and Dusignathus seftoni Deméré, San Diego Formation, California.

Bone and dentin were sampled for carbon and oxygen stable isotope analysis from the Late Pliocene San Diego Formation of southern California. Taxa sampled include three species of fossil pinniped as well as coeval species of whales, sirenians, fish and terrestrial mammals.

Chula Vista was also noteworthy as the first community in San Diego to require a paleontologist as part of a construction and grading project.

The fossils from this animal were located in the San Diego Formation, a stratum of Pliocene-age sandstone in the Rancho del Rey and Otay Ranch area of Chula Vista, California. The Neogene San Diego basin: a review of the marine Pliocene San Diego Formation.

Here we describe a new species of extinct porpoise, Semirostrum ceruttii, from the marine Pliocene San Diego (– mega-annum, Ma) and Purisima (5– Ma) formations of mandibles comprise a long, fused, and nearly edentulous prognathous symphysis, extending farther beyond the rostrum than in any known mammal.

The newly discovered Upper Miocene to Upper Pliocene San Gregorio assemblage 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. seftoni, the fur seal Callorhinus sp., cf. This process of translating and rifting Southern California away from North America has extended over the last 5 Ma and has produced a very complicated geology in Southern California--which, at the least, involves many northwest-trending right lateral and northeast-trending left lateral strike slip faults, transpressional mountain ranges, and.the coast between Orange County and the San Francisco region.

The appearance of the basins may have signaled the passage of what is now coastal southern and central California over the spreading zone. The rocks formed in these basins (Monterey Formation) are composed mainly of material derived from marine organisms, rather than terrestrial.
