    <p>(A) Manus-pes set with the 3D model and ichnites outline. (B-N) Isolated sets, manus and pes tracks with different states of preservation. (O) Pes track with digit scratches and large pes with prevalence of digits II, III and IV. Note the characteristic hooked digit tips (D-G), tracks resembling <i>Rhynchosauroides</i> due to the dragging of digit tips (E, I). All tracks scaled at 10 mm except the manus in (B), which is at 5 mm. All tracks are from Tossal de Pollerini site (Erillcastell).</p

    <i>Prorotodactylus mesaxonichnus</i> isp. nov. tracks IV.

    <p>(A) Trackway of the paratype IPS-93867 and outline of the ichnites. (B, C) Detail of a manus-pes set (B) and a pes track (C) of the trackway with the 3D models and correlated with the limbs of <i>Euparkeria capensis</i> (modified from Nesbitt, 2011 and Bernardi et al., 2015); note that bones and ichnites are at the same scale. (D) Paratype of a well-preserved pes completely overstepping the manus (IPS-93867). (E) Paratype of the manus-pes set of IPS-93871. (F, G) Right pes tracks with prevalence impression of digits II, III and IV (tridactyl function); M and P in (E) refer to manus and pes tracks, respectively.</p

    An archosauromorph dominated ichnoassemblage in fluvial settings from the late Early Triassic of the Catalan Pyrenees (NE Iberian Peninsula)

    <div><p>The vertebrate recovery after the end-Permian mass extinction can be approached through the ichnological record, which is much more abundant than body fossils. The late Olenekian (Early Triassic) tetrapod ichnoassemblage of the Catalan Pyrenean Basin is the most complete and diverse of this age from Western Tethys. This extensional basin, composed of several depocenters, was formed in the latest phases of the Variscan orogeny (Pangea breakup) and was infilled by braided and meandering fluvial systems of the red-beds Buntsandstein facies. Abundant and diverse tetrapod ichnites are recorded in these facies, including <i>Prorotodactylus mesaxonichnus</i> isp. nov. (tracks possibly produced by euparkeriids), cf. <i>Rotodactylus</i>, at least two large chirotheriid morphotypes (archosauriform trackmakers), <i>Rhynchosauroides</i> cf. <i>schochardti</i>, two other undetermined <i>Rhynchosauroides</i> forms, an undetermined Morphotype A (archosauromorph trackmakers) and two types of <i>Characichnos</i> isp. (swimming traces, here associated to archosauromorph trackmakers). The Pyrenean ichnoassemblage suggests a relatively homogeneous ichnofaunal composition through the late Early Triassic of Central Pangea, characterized by the presence of <i>Prorotodactylus</i> and <i>Rotodactylus</i>. Small archosauromorph tracks dominate and present a wide distribution through the different fluviatile facies of the Triassic Pyrenean Basin, with large archosaurian footprints being present in a lesser degree. Archosauromorphs radiated and diversified through the Triassic vertebrate recovery, which ultimately lead to the archosaur and dinosaur dominance of the Mesozoic.</p></div

    <p>Isolated impressions with a different preservation state (probably corresponding to undertracks or overtracks). Note the same kind of preservation despite tracks are small (A, C) or large (B). All tracks are from Port del Cant贸, at sections VI (A), VIII (B) and VII (C).</p
