Jefferson County is a county located in the Big Bend region in the northern part of the U.S. state of Florida. As of the 2020 census, the population was 14,510. Its county seat is Monticello.

<i>Camelops</i> Extinct genus of mammals

Camelops is an extinct genus of camel that lived in North and Central America, ranging from Alaska to Honduras, from the middle Pliocene to the end of the Pleistocene. It is more closely related to living camels than to lamines, making it a true camel of the Camelini tribe. Its name is derived from the Ancient Greek κάμηλος and ὄψ, i.e. "camel-face".

The Page–Ladson archaeological and paleontological site (8JE591) is a deep sinkhole in the bed of the karstic Aucilla River that has stratified deposits of late Pleistocene and early Holocene animal bones and human artifacts. The site was the first pre-Clovis site discovered in southeastern North America; radiocarbon evidence suggests that the site dates from 14,200 to 14,550 BP. These dates are roughly 1,000 to 1,500 years before the advent of the Clovis culture. Early dates for Page–Ladson challenge theories that humans quickly decimated large game populations in the area once they arrived.

The Aucilla River rises in Brooks County, Georgia, USA, close to Thomasville, and passes through the Big Bend region of Florida, emptying into the Gulf of Mexico at Apalachee Bay. Some early maps called it the Ocilla River. It is 89 miles (143 km) long and has a drainage basin of 747 square miles (1,930 km2). Tributaries include the Little Aucilla and Wacissa Rivers. In Florida, the Aucilla River forms the eastern border of Jefferson County, separating it from Madison County on the northern part, and from Taylor County to the south.

<span class="mw-page-title-main">Middle Awash</span> UNESCO World Heritage Site in Ethiopia

The Middle Awash is a paleoanthropological research area in the northwest corner of Gabi Rasu in the Afar Region along the Awash River in Ethiopia's Afar Depression. It is a unique natural laboratory for the study of human origins and evolution and a number of fossils of the earliest hominins, particularly of the Australopithecines, as well as some of the oldest known Olduwan stone artifacts, have been found at the site—all of late Miocene, the Pliocene, and the very early Pleistocene times, that is, about 5.6 million years ago (mya) to 2.5 mya. It is broadly thought that the divergence of the lines of the earliest humans (hominins) and of chimpanzees (hominids) was completed near the beginning of that time range, or sometime between seven and five mya. However, the larger community of scientists provide several estimates for periods of divergence that imply a greater range for this event, see CHLCA: human-chimpanzee split.

<i>Bison latifrons</i> Extinct species of mammal

Bison latifrons, also known as the giant bison or long-horned bison, is an extinct species of bison that lived in North America during the Late Pleistocene epoch ranging from southern Canada to Mexico. It is noted for large body size and its distinctive long horns.

<span class="mw-page-title-main">Wacissa River</span> River in Florida, United States of America

The Wacissa River is a large, spring-fed stream located in south-central Jefferson County, Florida. Its headwaters are located about a mile south of the town of Wacissa, where the river emerges crystal clear from a group of large limestone springs. From its headsprings, the river flows approximately 12 miles (19 km) south through a broad cypress swamp before breaking into numerous braided channels which join the Aucilla River a few miles further south. The river is managed by the Florida Fish & Wildlife Conservation Commission as part of the Aucilla Wildlife Management Area, and has been declared an Outstanding Florida Waterway by the Florida Department of Environmental Protection.

Melbourne Bone Bed is a paleontological site located at Crane Creek in Melbourne, in the U.S. state of Florida. This site contains fossils from the Late Pleistocene period 20,000 to 10,000 years before the present. The fossils include extinct animals such as varieties of camels, dire wolves, Florida cave bears, giant armadillos, giant beavers, giant bison, giant ground sloths, mammoths, mastodons, saber-toothed cats, and tapirs.

<i>Tremarctos floridanus</i> Extinct species of bear

Tremarctos floridanus is an extinct species of bear in the family Ursidae, subfamily Tremarctinae. T. floridanus became extinct at the end of the last ice age, 11,000 years ago. It's fossils have been found throughout the Southeastern United States, in northeastern Mexico, and in Belize from the Rancholabrean epoch, and from earlier epochs at some sites in western North America.
