Trace fossils from alluvial fan deposits were only rarely described worldwide. Here we document an association of meniscate backfilled burrows in the alluvial cone of Sarzedas. The upper Tortonian-Messinian Torre Formation is composed of syntectonic debris flows and sheet-flood facies that pass distally into fine-grained micaceous sandstones...

The largest ever described Cruziana, more than 200 mm wide, are not uncommon in the Lower-to-Middle Ordovician Armorican Quartzite Formation, at the Ichnological Park of Penha Garcia, central Portugal. They are the most visible trace fossils of ichnocoenoses dominated by classic arthropod intrastratal burrows, tunnels, and trackways, and...

Thick quartzite beds with large bedding planes exposures thoroughly bioturbated with Deadalus desglandi, that can be followed for several kilometers, were discovered in the Lower Ordovician (Floian) of the Armorican Quartzite Formation at Muradal Mountain, UNESCO Naturtejo Geopark (Central Portugal). The complex architecture of this form of...

The revision of the classic collections of trace fossils housed in the Geological Museum of the former Geological Survey of Portugal is bringing new information to well established ichnogenera. Through the revision of the type material of Taenidium lusitanicum Heer, 1881 and other specimens housed in the Geological Museum of Lisbon and the...

A review with the description of the low diverse ichnoassembla - ges from the slates of Valongo Formation is made for the first time. Among the organic-rich mining, simple trace fossils dominated by Planolites-like worm burrows and very rare Chondrites developed in short-termed dysoxic intervals, we describe Phycodes canelensis nov. isp. as an...

Ichnology is a powerful tool for understanding the evolutionary paths of animal clades, through the paleobiology of behavior preserved in Lagerstätten such as the Cabeço da Ladeira (Portugal) site. Here, the peritidal carbonates of the Chão das Pias Formation (Middle Jurassic, upper Bajocian) record the development of microbial mats in a tidal...
