Lower Permian deposits of the Boskovice Basin in the Czech Republic have long been renowned for extraordinarily abundant specimens of discosauriscid seymouriamorphs, some of which showing exceptional preservation, including widespread soft tissues. The only other tetrapods from the strata are represented by rare temnospondyls. However, recent fieldwork in the Asselian (lowermost Permian) of the Boskovice Basin has yielded a diverse assemblage of tetrapod tracks, illuminating a hidden terrestrial tetrapod diversity. Here, we describe well-preserved isolated tracks, manus-pes couples, and a slab with trackways composed of approximately 20 tracks in at least four different directions belonging to early-diverging, or ‘pelycosaur-grade’, synapsids. The material originates from three localities situated within the Letovice and Padochov formations and is assignable to the ichnotaxon Dimetropus. The best-preserved specimen further shows rare skin impressions, which have not been observed from the hands or feet of early-diverging mammal-line amniotes before. The new material adds to the scarce record of synapsids from the Carboniferous/Permian transitional interval of equatorial Pangea. At the same time, it highlights the significance of the ichnological record of the Boskovice Basin which has long been neglected despite offering evidence for the presence of diverse faunal components that have not been reported from these basinal deposits before.

Moradisaurine captorhinid eureptiles are one of the best-known groups of Permian herbivorous tetrapods. Moradisaurines, with several rows of teeth on the maxillae and jaws, first appeared in the Cisuralian and went extinct at the end of the Lopingian; they were especially abundant in the equatorial latitudes of Pangaea. However, the postcranial skeleton of this clade is relatively poorly known, given that most of the species described have been based on skulls. This fact has precluded a detailed correlation with coeval tracks. The present work describes a new moradisaurine genus and species, Tramuntanasaurus tiai, based on an almost complete, semiarticulated skeleton from the Port des Canonge Formation of Mallorca (Balearic Islands, western Mediterranean), identifying it as the trackmaker of the co-occurring small-sized traces of the ichnogenus Hyloidichnus. Apart from documenting the new moradisaurine species, the results presented herein strongly support the hypothesis that Hyloidichnus was produced by both non-moradisaurine captorhinids and moradisaurines; those of small to medium size, at least, had a very conserved autopodial morphology and gait. Therefore, this study provides new data to infer the trackmakers of Hyloidichnus where bone remains are missing, and thus contributes to our understanding of Permian tetrapod ichnofaunas and tetrapod communities.
