Titanis Walleri
''Titanis'' was an extinct genus of giant flightless terror birds that inhabited North America during the early Pliocene to early Pleistocene epochs. The generic name, ''Titanis'', refers to the titans, Ancient Greek gods that preceded the Twelve Olympians, in allusion to the bird's size. The specific name, ''T. walleri'', honors the holotype's collector, Benjamin I. Waller, an avocational underwater archaeologist. ''Titanis'' was thought to be carnivorous and most likely preyed on the many small mammals of the time period. This giant flightless bird was one of the most efficient predators of its time in North America. Description ''Titanis'' was approximately tall and around in weight. When compared with other phorusrhacids, the examined material indicates a large variation in the size of ''Titanis'', perhaps indicating strong sexual dimorphism. It had long, agile legs, and three-toed feet with long talons. It could undoubtedly run at high speeds when hunting. Though its ...

Phorusrhacidae
Phorusrhacids, colloquially known as terror birds, are an extinct clade of large carnivorous flightless birds that were one of the largest species of apex predators in South America during the Cenozoic era; their conventionally accepted temporal range covers from 62 to 0.1 million years ( Ma) ago. They ranged in height from . Their closest modern-day relatives are believed to be the seriemas. ''Titanis walleri'', one of the larger species, is known from Texas and Florida in North America. This makes the phorusrhacids the only known large South American predator to migrate north in the Great American Interchange that followed the formation of the Isthmus of Panama land bridge (the main pulse of the interchange began about 2.6 Ma ago; ''Titanis'' at 5 Ma was an early northward migrant). It was once believed that ''T. walleri'' became extinct in North America around the time of the arrival of humans, but subsequent datings of ''Titanis'' fossils provided no evidence for their surv ...

Columbia County, Florida
Columbia County is a county located in the north central portion of the U.S. state of Florida. As of the 2020 census, the population was 69,698, up from 67,531 at the 2010 census. Its county seat is Lake City. Columbia County comprises the Lake City, FL Micropolitan Statistical Area, which is included in the Gainesville-Lake City, FL Combined Statistical Area. Osceola National Forest is partially in Columbia County. History After Florida became a territory of the United States in 1821, pioneer and immigrant settlers from the United States formed their own settlement adjacent to a Seminole village called Alligator Village, and called it Alligator. Following the 1823 Treaty of Moultrie Creek, the residents of Alligator village relocated to the banks of Peace Creek in the newly established Seminole reservation, leaving Alligator Town on its own. When Columbia County was formed in 1832 from Duval and Alachua counties, Alligator Town was designated as the seat of the county go ...

Gilchrist County, Florida
Gilchrist County is a county located in the north central part of the U.S. state of Florida. Organized in 1925 from the western part of Alachua, it is the last county to be formed in the state. As of the 2020 census, the population was 17,864. The county seat is Trenton. Gilchrist County is included in the Gainesville, FL Metropolitan Statistical Area. History Gilchrist County was created in 1925, the last county organized in Florida. It was named for Albert W. Gilchrist, Governor of Florida from 1909 to 1913. It was formed by residents of what was then western Alachua County, as they believed they were not getting adequate representation on the county commission. With the poor roads of the time, they felt it took too long to get to the county seat of Gainesville. They disagreed about a proposed law that would require fencing in cattle in the rural area. They also believed that they would be better off by getting their own share of racetrack revenues, which the state dist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Fe River (Florida)
The Santa Fe River is a river in northern Florida. The watershed of the river is approximately and spreads across southern Columbia County, Florida, Columbia, southern Suwannee County, Florida, Suwannee, western Bradford County, Florida, Bradford, far southern Baker County, Florida, Baker, Union County, Florida, Union, northern and eastern Gilchrist County, Florida, Gilchrist, and northern Alachua County, Florida, Alachua counties. The headwaters of the river are Lake Santa Fe, near Keystone Heights, Florida, Keystone Heights. The Santa Fe River is usually a slow-flowing river. This slow speed, combined with the abundant leaf-drop from nearby trees, especially Taxodium distichum, Bald Cypress, leads to a very Blackwater river, dark-brown river due to dissolved tannins. The Santa Fe River is typical of many rivers in karst regions in that it completely disappears underground and then reappears downstream. The river drops into a large sinkhole in O'Leno State Park and reappe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blancan
The Blancan North American Stage on the geologic timescale is the North American faunal stage according to the North American Land Mammal Ages chronology (NALMA), typically set from 4,750,000 to 1,806,000 years Before Present, BP, a period of . Blancan North American Stage GeoWhen Database. Version 1.1.0. Retrieved 2017-June-26. It is usually considered to start in the early-mid Pliocene Epoch and end by the early Pleistocene. The Blancan is preceded by the Hemphillian and followed by the Irvingtonian NALMA stages. As usually defined, it corresponds to the mid-Zanclean through Piacenzian and Gelasian stages in Europe and Asia.

Cariamae
Cariamiformes (or Cariamae) is an order of primarily flightless birds that has existed for over 60 million years. The group includes the family Cariamidae (seriemas) and the extinct families Phorusrhacidae, Bathornithidae, Idiornithidae and Ameghinornithidae. Though traditionally considered a suborder within Gruiformes, both morphological and genetic studies show that it belongs to a separate group of birds, Australaves, whose other living members are Falconidae, Psittaciformes and Passeriformes. This proposal has been confirmed by a 2014 study of whole genomes of 48 representative bird species. This analysis shows that the Cariamiformes are basal among extant Australaves, while falcons are next most basal; in combination with the fact that the two most basal branches of Afroaves (New World vultures plus Accipitriformes, and owls) are also predatory, it is inferred that the common ancestor of 'core landbirds' (Telluraves) was an apex predator. However, some researchers like Da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seriema
The seriemas are the sole living members of the small bird family Cariamidae, which is also the only surviving lineage of the order Cariamiformes. Once believed to be related to cranes, they have been placed near the falcons, parrots and passerines, as well as the extinct Phorusrhacidae (terror birds).Hackett, S. J. ''et al''.

Dromaeosauridae
Dromaeosauridae () is a family of feathered theropod dinosaurs. They were generally small to medium-sized feathered carnivores that flourished in the Cretaceous Period. The name Dromaeosauridae means 'running lizards', from Greek ('), meaning 'runner', and ('), meaning 'lizard'. In informal usage, they are often called raptors (after ''Velociraptor''), a term popularized by the film '' Jurassic Park''; a few types include the term "raptor" directly in their name and have come to emphasize their bird-like appearance and speculated bird-like behavior. Dromaeosaurid fossils have been found across the globe in North America, Europe, Africa, Asia, South America and Antarctica, with some fossils giving credence to the possibility that they inhabited Australia as well. They first appeared in the mid-Jurassic Period (late Bathonian stage, about 167 million years ago) and survived until the end of the Cretaceous (Maastrichtian stage, 66 ma), existing until the Cretaceous–Paleogene ex ...

Theropod
Theropoda (; ), whose members are known as theropods, is a dinosaur clade that is characterized by hollow bones and three toes and claws on each limb. Theropods are generally classed as a group of saurischian dinosaurs. They were ancestrally carnivorous, although a number of theropod groups evolved to become herbivores and omnivores. Theropods first appeared during the Carnian age of the late Triassic period 231.4 million years ago ( Ma) and included all the large terrestrial carnivores from the Early Jurassic until at least the close of the Cretaceous, about 66 Ma. In the Jurassic, birds evolved from small specialized coelurosaurian theropods, and are today represented by about 10,500 living species. Biology Diet and teeth Theropods exhibit a wide range of diets, from insectivores to herbivores and carnivores. Strict carnivory has always been considered the ancestral diet for theropods as a group, and a wider variety of diets was historically considered a characteri ...
