AB Lower and Middle Ordovician rocks outcropping in the Cabañeros National Park (Central Iberian Zone)are being explored within a mapping project aimed at identifying geosites representative of the geologicaland paleontological heritage on this natural area. Ongoing field-work has led to the discovery of threefossil localities that bring out significant paleontological data relevant to the whole Iberian Massif. Theoldest comes from the upper part of the Armorican Quartzite Fm. (Floian/middle Arenigian) and is a largeichnofossil identified as Tumblagoodichnus? isp., which probably represents a shallow burrow filled bycollapse of sand from above, and dug as a temporary refuge by a large arthropod. The trace is 45 cm wide,much bigger than the large arthropod traces previously reported from the Iberian Ordovician (rare Cruzianareach up to 26 cm in width). The second fossil locality lies towards the middle part of the overlyingMarjaliza Beds (Dapingian to lower Darriwilian/middle-upper Arenigian) and is represented by a thickcoquina of paleotaxodont and paleoheterodont bivalves, apparently formed due to a catastrophic event(an exceptional storm?) that transported and entombed en masse millions of individuals now preserved ascomplete specimens with closed valves. This local abundance strongly contrasts with the scarcity of Arenigianbivalves preserved in the Cruziana sandstone facies of SW Europe. Finally, the youngest locality is a richfossiliferous bed of lower Oretanian (Darriwilian) age recorded in the Navas de Estena Shales, where thebrachiopod genus Eodalmanella (Ranorthidae) makes its second European occurrence and reinforces theIbero-Bohemian paleobiogeographic affinities
