Barbados Rail
Encyclopedia
The Barbados Rail is a fossil rail
species endemic to Barbados
with an undetermined taxonomic status. It was formerly described by Pierce Brodkorb
in 1965 as Fulica podagrica. However, this classification has been questioned by Storrs Olson when he described Brodkorb's material anew in 1974. It is only known by Brodkorb's holotype which consists of a humerus
and several leg elements including femur
, tibiotarsus
and tarsometatarsus
fragments. The humerus may not be specifically distinct from those of the American Coot
(Fulica americana) or the Caribbean Coot
(Fulica caribaea) but most of the femur, tibiotarsus and tarsometarsus fragments are from a yet undescribed larger rail of an undetermined genus not related to Fulica. Olson further assumed that Brodkorb's material might be a composite of several rail species. The bone fragments were unearthed in Late Pleistocene

Femur
The femur , or thigh bone, is the most proximal bone of the leg in tetrapod vertebrates capable of walking or jumping, such as most land mammals, birds, many reptiles such as lizards, and amphibians such as frogs. In vertebrates with four legs such as dogs and horses, the femur is found only in...
, tibiotarsus
Tibiotarsus
The tibiotarsus is the large bone between the femur and the tarsometatarsus in the leg of a bird. It is the fusion of the proximal part of the tarsus with the tibia.A similar structure also occurred in the Mesozoic Heterodontosauridae...

Late Pleistocene
The Late Pleistocene is a stage of the Pleistocene Epoch. The beginning of the stage is defined by the base of the Eemian interglacial phase before the final glacial episode of the Pleistocene 126,000 ± 5,000 years ago. The end of the stage is defined exactly at 10,000 Carbon-14 years BP...

Deposition (geology)
Deposition is the geological process by which material is added to a landform or land mass. Fluids such as wind and water, as well as sediment flowing via gravity, transport previously eroded sediment, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of...

Etymology
Brodkorb's previous species epithet is derived from the Greek term "podagrikos" (which means affected with goutGout
Gout is a medical condition usually characterized by recurrent attacks of acute inflammatory arthritis—a red, tender, hot, swollen joint. The metatarsal-phalangeal joint at the base of the big toe is the most commonly affected . However, it may also present as tophi, kidney stones, or urate...
