Cirrus fibratus or also called Cirrus filosus [2] is a species of cirrus cloud. The name cirrus fibratus is derived from Latin, meaning "fibrous".[3] These clouds are similar to cirrus uncinus, commonly known as "mares' tails"; however, fibratus clouds do not have tufts or hooks at the end.[4] The filaments are usually separate from one another.[5]

Like other cirrus clouds, cirrus fibratus occur at high altitudes. They can indicate an approaching warm front;[6] however, they can also be an indication that fair weather will follow.[7]
