Cosesaurus - Slender hairs, first identified as proto-feather divisions by Ellenberger (1978, 1993, emerge from the entire length of the tail.

Longisquama - Difficult to determine, but possible hairs gathered at the tail tip form a primitive decoration convergent with the vane of later pterosaurs

Anurognathus - Tail hairs restricted to posterior half of the tail vestige.

Batrachognathus - Only a few long hairs tip the vestigial tail.

Campylognathoides - The tail hairs coalesce to become a vertical tail vane that acts as a secondary sexual signal and passively reorients the tail tip in line with the flight path like feathers on an arrow.

Rhamphorhynchus intermedius - Phylogenetic size reduction included tail vane reduction.

Rhamphorhynchus (Vienna specimen) - The vane assumes a diamond shape.

Sordes - An atypical expansion of the distal tail bones including just a few tail hairs forming a vane shape, but not a vane.

Dorygnathus (Donau specimen) - The tail hairs coalesce at the tip but do not form a vane.

Dorygnathus SMNS 50164 - More substantial tail hairs indicated.

Pterorhynchus - Several dozen vanelets extend down the posterior half of the tail. These could be individually expanded tail hairs.

Scaphognathus (Maxburg specimen) - An ephemeral trinagular tail vane may have been present. Subsequent taxa appear to reduce this.
