Temporal range: Pragian
Rhyniella is a genus of fossil springtails (Collembola) from the Rhynie chert, which formed during the Pragian stage of the Early Devonian. One species has been described, Rhyniella praecursor. Its name means "small creature of the Rhynie chert, a forerunner [of modern hexapoda]". For some time it was believed to be the only hexapod from the Early Devonian (c. ).
Rhyniella grew to a length of about 1–2 mm and would have been a scavenger, feeding on rotting matter.
