Paraplesiobatis heinrichsi is a lightly armored pseudopetalichthyid placoderm from the Hunsrückschiefer Lagerstätte of Early Devonian Germany. The type and only known specimen is an articulated, but very incomplete individual consisting of a large, incomplete, plate-covered head, and some of the vertebral column, with a total length of 10 centimeters. The specimen strongly resembles Pseudopetalichthys to the point that many experts suggest they may be of the same genus or species,^[1] though because the only specimens of both genera are so poorly preserved, talk of synonymizing the two can not begin (let alone continue) until more, better preserved specimens are found.^[1]
