Thus, three new ichnospecies Matthew described appeared in the 1975 <em>Treatise on Invertebrate Paleontology</em> as “unrecognized or unrecognizable” and were mostly forgotten by vertebrate ichnologists. These traces include <em>Hylopus </em>(?)<em> variabilis, Nanopus </em>(?)<em> vetustus</em> and <em>Bipezia bilobata</em>. One ichnospecies, <em>Hylopus</em> (?) <em>variabilis</em>, here is retained as a valid tetrapod footprint ichnotaxon and reassigned to the ichnogenus <em>Limnopus</em> as a new combination, together with other poorly preserved specimens Matthew labeled, but never described. <em>Nanopus</em> (?) <em>vetustus</em> and <em>Bipezia bilobata</em> named by Matthew in the same paper, have been reexamined and remain as nomina dubia.</p><p> </p>}, journal={Atlantic Geoscience}, author={Stimson, Matthew R. and Miller, Randall F. and Lucas, Spencer G.}, year={2016}, month={Jan.}, pages={021–035} }
