Phlaocyon Leucosteus
''Phlaocyon'' (from Greek ''phlao'', "eat greedily" and ''cyon'', "dog") is an extinct genus of the Borophaginae subfamily of canids native to North America. It lives from the Early Oligocene to the Early Miocene epoch 33.3–16.3 Mya, existing for approximately . It is closely related to ''Cynarctoides''. Phylogeny When discovered in the 19th century and during the following decades, ''Phlaocyon'' was thought to be ancestral to raccoons because of shared convergent adaptations toward hypocarnivorous dentitions, but was the first to discover the canid nature of the middle ear region in ''P. leucosteus'' and ''Phlaocyon'' in now believed to be part of very diverse clade of hypocarnivorous canids, the Phlaocyonini, and only distantly related to raccoons. '' P. mariae'' and '' P. yatkolai'', both known from isolated teeth and fragmentary material, are the largest and most derived species, and both display a tendency away from the hypocarnivorous dentition of the genus and to ...

Borophaginae
The extinct Borophaginae form one of three subfamilies found within the canid family. The other two canid subfamilies are the extinct Hesperocyoninae and extant Caninae. Borophaginae, called "bone-crushing dogs", were endemic to North America during the Oligocene to Pliocene and lived roughly 34—2.5 million years ago, existing for about . Origin The Borophaginae descended from the subfamily Hesperocyoninae. The earliest and most primitive borophagine is the genus ''Archaeocyon'', which is a small fox-sized animal mostly found in the fossil beds in western North America. The borophagines soon diversified into several major groups. They evolved to become considerably larger than their predecessors, and filled a wide range of niches in late Cenozoic North America, from small omnivores to powerful, bear-sized carnivores, such as ''Epicyon''. Species There are 66 identified borophagine species, including 18 new ones that range from the Orellan to Blancan ages. A phylogenetic anal ...

Suwannee County, Florida
Suwannee County is a county located in the north central portion of the state of Florida. As of the 2020 census, the population was 43,474, up from 41,551 in 2010. Its county seat is Live Oak. Suwannee County was a dry county until August 2011, when the sale of alcoholic beverages became legal in the county. History Suwannee County was created in 1858, as railways were constructed through the area connecting it to Jacksonville, Tallahassee, and points north. It was named after the Suwannee River, which forms the county's northern, western, and much of its southern border. The word "Suwannee" may either be a corruption of the Spanish ''San Juan'' ("Saint John") or from the Cherokee ''sawani'' ("echo river"). The rural areas supported numerous lumber and turpentine camps. In the 1930s, anthropologist Zora Neale Hurston did research in North Florida timber camps.

Hernando County, Florida
Hernando County is a county located on the west central coast of the U.S. state of Florida. As of the 2020 census, the population was 194,515. Its county seat is Brooksville, and its largest community is Spring Hill. Hernando County is included in the Tampa-St. Petersburg-Clearwater, FL Metropolitan Statistical Area. As of 2005, Hernando was the 35th fastest-growing county in the country. History Around 1840, Fort DeSoto was established in present-day Hernando County in the northeast edge of present-day Brooksville to protect settlers in the area from Native Americans. Fort DeSoto became a small community center, trading post, and way station on the route to Tampa. Settlements started to grow near the fort beginning around 1845; two towns developed, Melendez and Pierceville, which would later merge to create Brooksville in 1856. Then encompassing a significantly larger area of west central Florida than it does today, Hernando County was officially established on February ...

Wheeler County, Oregon
Wheeler County is a county in the U.S. state of Oregon. As of the 2020 census, the population was 1,451, making it Oregon's least populous county. It is named in honor of , an early settler who owned a farm near Mitchell. The county seat is Fossil, and Wheeler County is known for having Oregon's largest deposit of fossils. History Wheeler County was created on February 17, 1899, from parts of Grant, Gilliam, and Crook Counties. There have been no boundary changes since its creation. Fossil was designated the temporary county seat at the time of the county's creation. In 1900 there was an election to determine the permanent county seat between the three towns of the county, which ended with Fossil winning the election. Henry H. Wheeler (born September 7, 1826, Erie County, Pennsylvania - died March 26, 1915, Mitchell, Oregon) arrived in Oregon in 1862, moved around, and settled near Mitchell, Oregon. He married Dorcas L.

John Day Formation
The John Day Formation is a series of rock strata exposed in the Picture Gorge district of the John Day River basin and elsewhere in north-central Oregon in the United States. The Picture Gorge exposure lies east of the Blue Mountain uplift, which cuts southwest–northeast through the Horse Heaven mining district northeast of Madras. Aside from the Picture Gorge district, which defines the type, the formation is visible on the surface in two other areas: another exposure is in the Warm Springs district west of the uplift, between it and the Cascade Range, and the third is along the south side of the Ochoco Mountains. All three exposures, consisting mainly of tuffaceous sediments and pyroclastic rock rich in silica, lie unconformably between the older rocks of the Clarno Formation below and Columbia River basalts above. Stratigraphy The strata, which vary in age from 39 million years to 18 million years, were formed mainly from ashfalls from volcanoes due to a series of ...
