Kolponomos
''Kolponomos'' is an extinct genus of carnivoran mammal that existed in the Late Arikareean North American Land Mammal Age, early Miocene epoch, about 20 million years ago. It was likely a marine mammal. The genus was erected in 1960 by Ruben A. Stirton, a paleontologist at the University of California Museum of Paleontology, Berkeley, for the species ''K. clallamensis'', on the basis of a partial skull and jaw found on the Olympic Peninsula. At the time, Stirton questionably assigned it to Procyonidae, its systematic position remained problematic until the discovery of more fossils including a nearly complete cranium from the original locality of ''K. clallamensis'' which helped identify it as part of the group from which pinnipeds evolved. Description In life, species of ''Kolponomos'' had downturned snouts and broad, heavy molars that would have been suited to a diet of hard-shelled marine invertebrates, and their narrow snouts and anteriorly directed eyes indicate that they ...

Douglas Emlong
Douglas Ralph Emlong (April 17, 1942–June 1980) was an amateur fossil collector from the Oregon Coast in the northwestern United States. His collections contributed to the discovery and description of numerous extinct marine mammal species, many of which are ancestral to extant groups. Described as an 'indefatigable' fossil collector with 'Promethian prowess in discovery of unprecedented vertebrate fossils', he contributed substantially to the field from the age of fourteen. The ancestral pinniped '' Enaliarctos emlongi'' was named in his honor by Annalisa Berta in 1991. Discoveries Fossils discovered by Douglas Emlong include: Marine Mammals: *''Aetiocetus cotylalveus'', an early, toothed relative of baleen whales and evolutionary link between ancient and modern cetaceans *'' Simocetus'', a genus of bottom-feeding pug-nosed whales which may have had comparable echolocation abilities to modern toothed whales *''Behemotops'', a genus of primitive, elephant-like desmostylians ...

Siamogale Melilutra
''Siamogale melilutra'' is an extinct species of giant otter from the late Miocene from Yunnan province, China. Ranking among the largest fossil otters, ''Siamogale'' represents a feeding ecomorphology with no living analog. Its giant size and high mandibular strength confer Durophagy, shell-crushing capability matched only by other extinct Molluscivore, molluscivores, such as the bear-like marine stem-pinniped ''Kolponomos''. Taxonomy The skull reveals a combination of otter-like and badger-like cranial and dental characteristics. The new species belongs to the Lutrinae because of its possession of a large infraorbital canal and ventral expansion of the mastoid process, among other traits. ''Siamogale melilutra'' was about 1.9 m (6.25 ft) in overall length and weighed at least 40 kg (88 pounds). The remains of the skull were found in China and were re-created with a special program called the CT scan which is able to reconstruct the skeleton without being damaged. ...

Clallam Bay, Washington
Clallam Bay is an unincorporated community and census-designated place (CDP) in Clallam County, Washington, United States, at the mouth of the Clallam River into Clallam Bay. Known for its natural environment and hunting, Clallam Bay is partially reliant on tourism. Clallam Bay is considered the twin city of nearby Sekiu. As of the 2010 census, the population of Clallam Bay was 363. History Clallam Bay was founded in the 1880s as a steamboat stop. It became a mill town in 1890. Two years later, the mill burned, and making barrels for West Clallam Bay's tanning extract became its main industry. In 1905, the lighthouse at Slip Point was lighted on April Fool's Day. Sekiu Point (pronounced "See'-kew"), the western cape of Clallam Bay, was first charted by Captain Henry "OG" Kellett in 1847. The town of Sekiu was founded as "West Clallam" in 1870, by A.J. Martin who built a salmon cannery to be nearer the fishing grounds. The area boomed before the turn of the century when a leath ...

Prehistoric Marine Mammals
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene Bears
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tectonic
Tectonics (; ) are the processes that control the structure and properties of the Earth's crust and its evolution through time. These include the processes of mountain building, the growth and behavior of the strong, old cores of continents known as cratons, and the ways in which the relatively rigid plates that constitute the Earth's outer shell interact with each other. Tectonics also provide a framework for understanding the earthquake and volcanic belts that directly affect much of the global population. Tectonic studies are important as guides for economic geologists searching for fossil fuels and ore deposits of metallic and nonmetallic resources. An understanding of tectonic principles is essential to geomorphologists to explain erosion patterns and other Earth surface features. Main types of tectonic regime Extensional tectonics Extensional tectonics is associated with the stretching and thinning of the crust or the lithosphere. This type of tectonics is found ...

Newport, Oregon
Newport is a city in Lincoln County, Oregon, United States. It was incorporated in 1882, though the name dates back to the establishment of a post office in 1868. Newport was named for Newport, Rhode Island. As of the 2010 census, the city had a total population of 9,989, an increase of nearly 5% over its 2000 population; as of 2019, it had an estimated population of 10,853. The area was originally home to the Yacona tribe, whose history can be traced back at least 3000 years. White settlers began homesteading the area in 1864. The town was named by Sam Case, who also became the first postmaster. Newport has been the county seat of Lincoln County since 1952, when voters approved a measure to move the center of government from nearby Toledo to Newport. It is also home of the Oregon Coast Aquarium, Hatfield Marine Science Center, Nye Beach, Yaquina Head Light, Yaquina Bay Light, Pacific Maritime Heritage Center and Rogue Ales, and is notable as the western terminus of U.S. R ...

Concretion
A concretion is a hard, compact mass of matter formed by the precipitation of mineral cement within the spaces between particles, and is found in sedimentary rock or soil. Concretions are often ovoid or spherical in shape, although irregular shapes also occur. The word 'concretion' is derived from the Latin "(act of) compacting, condensing, congealing, uniting", itself from ''con'' meaning 'together' and ''crescere'' meaning "to grow". Concretions form within layers of sedimentary strata that have already been deposited. They usually form early in the burial history of the sediment, before the rest of the sediment is hardened into rock. This concretionary cement often makes the concretion harder and more resistant to weathering than the host stratum. There is an important distinction to draw between concretions and nodules. Concretions are formed from mineral precipitation around some kind of nucleus while a nodule is a replacement body. Descriptions dating from the 18th ce ...
