Its tenth (outermost) primary remex is quite reduced for example.

All these systems except the Remex Bi-Klon (which arrived too late to test) are available for less than $100.

The feather has a relatively low degree of asymmetry, which Speakman and Thompson in 1994 concluded to indicate it as a secondary remex.

In these birds, the fifth set of secondary covert feathers does not cover any remex, possibly due to a twisting of the feather papillae during embryonic development.

The wood processing industry is represented by companies such as Larix, Gralemn, Remex, Bucin-Mob, Prolemn, and Amis.

As the feather bears little resemblance to the retrices of the other full Archaeopteryx skeletons, it is generally thought to be a wing feather: Griffiths and others have concluded it was a remex, while Carney in 2012 interpreted it to be a covert feather.

Flight feathers are the long, stiff, asymmetrically shaped, but symmetrically paired feathers on the wings or tail of a bird; those on the wings are called remiges (singular remex) while those on the tail are called rectrices (singular rectrix).
