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]
Orchesella cincta, furca. 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]
If the proportions between body length and chelicerae match those of its closest relatives, where the ratio between claw size and body length is relatively consistent, the specimen of Jaekelopterus that possessed the chelicera in question would have measured between 233 and 259 centimeters (7.64 and 8.50 ft), an average 2.5 meters (8.2 ft), in ...
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.
[1] According to recent research, the forked cross emerged under the influence of the mystics in the late 13th or early 14th century and is especially common in the German Rhineland , where it is also called a Gabelkreuz ("fork cross"), Mystikerkruzifix ("mystic's cross"), Gabelkruzifix ("fork crucifix"), Schächerkreuz ("robber's cross"), or ...

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]
