Suwanee Point
The Suwannee point is a large unfluted lanceolate Paleo-Indians projectile point that features a recurvate profile with a slightly narrowed waist and a convex base. The point is one of the earliest forms of lanceolate types and is dated between 10500–9500 Before Present. It represents a typical example of the Middle Paleoindian subperiod. Experts are divided over whether the type predates or postdates the Clovis point but have noted that the two share similarities in their construction. Suwanee specimens are generally unfluted, which distinguishes them from the generally fluted Clovis. However, a few rare examples of fluted Suwanee have also been discovered. The largest concentration of Suwanee points appear in Florida, where the classification was first named in 1968 by Ripley P. Bullen for Suwannee County 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.

Lanceolate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Projectile Point
In North American archaeological terminology, a projectile point is an object that was hafted to a weapon that was capable of being thrown or projected, such as a javelin, dart, or arrow. They are thus different from weapons presumed to have been kept in the hand, such as knives, spears, axes, hammers, and maces. Stone tools, including projectile points, can survive for long periods, were often lost or discarded, and are relatively plentiful, especially at archaeological sites. They provide useful clues to the human past, including prehistoric trade. A distinctive form of point, identified though lithic analysis of the way it was made, is often a key diagnostic factor in identifying an archaeological industry or culture. Scientific techniques exist to track the specific kinds of rock or minerals that were used to make stone tools in various regions back to their original sources. As well as stone, projectile points were also made of worked wood, bone, antler, horn, or ivory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Before Present
Before Present (BP) years, or "years before present", is a time scale used mainly in archaeology, geology and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1 January 1950 as the commencement date (epoch) of the age scale. The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, which scientists must now account for. In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation RCYBP stands for the explicit "radio carbon years before present". Usage The BP scale is sometimes used for dates established by means other than radiocarbon dating, such as stratigraphy. This usage differs from t ...

Suwannee County
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. Geography According to the U.S. Census Bureau, the county has a total area of , of which is land and (0.5%) is wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
