Insights on the evolution of synapsid locomotion based on tetrapod tracks from the lower Permian of Mallorca (Balearic Islands, western Mediterranean)

“Pelycosaur”-grade synapsids were a successful group of terrestrial tetrapods that lived during the Carboniferous and Permian, utilising a wide diversity of ecological niches. They are considered the trackmakers of the ichnogenera Dimetropus and possibly also Dromopus and Tambachichnium, found in upper Palaeozoic deposits of North America, North Africa and Europe. Here we describe a new morphotype from the lower Permian of Mallorca (Balearic...
