Furca, a prehistoric arthropod; Furca (springtail), an anatomical structure in springtail entognaths. Caudal furca ("tail fork"), part of the telson of some crustaceans; Furcula, the wishbone of birds and some dinosaurs; Furcula a genus of Noctuid moths; Any small forked structure of animal anatomy
Furca fossils have been found in sediments indicative of shallow marine habitats. Since appendages and other body parts are unknown, no firm conclusions can be made of the biology of Furca. However, comparisons to other marrellomorphs and living arthropods such as horseshoe crabs suggest a benthic marine lifestyle: dwelling on the sea floor. [2]
The furcula, or furca is a forked, tail-like appendage. It is present in most species of springtails , and in them it is attached ventrally to the fourth abdominal segment. The organ most often is present in species of Collembola that lives in the upper soil layers where it is used for jumping to avoid predators. [ 1 ]
River bifurcation (from Latin: furca, fork) occurs when a river (a bifurcating river) flowing in a single channel separates into two or more separate streams (called distributaries) which then continue downstream. Some rivers form complex networks of distributaries, typically in their deltas.
The presence of furca in the type B appendage is also possible and the structure may represent the unfused tips of the appendages. Located between the dorsal and ventral surfaces of the Blattfüsse associated with the type A appendages is a set of organs traditionally described as either "tubular organs" or "horn organs".

Forked cross Forked cross in St. Mary's in the Capitol, Cologne. A forked cross, is a Gothic cross in the form of the letter Y that is also known as a crucifixus dolorosus, furca, ypsilon cross, Y-cross, robber's cross or thief's cross.
Furcacauda is a genus of thelodontid agnathan from the Lower Devonian of Canada, and is the type genus of the order Furcacaudiformes. [2] Furcacaudiform thelodontids were deep water jawless vertebrates with symmetrical fork and lobed-finned tails and scales smaller than typical loganellid and nikoliviid thelodonti scales. [1]
