The Campanian Anacleto Formation holds an abundant and diverse ichnofossil body-fossil vertebrate record. Despite the striking diversity of this record, pterosaur fossils had never been described from unit. Here, we report four manus tracks fluvial red beds cropping out in Área Natural Protegida Municipal Paso Córdoba (Río Negro Province, northern Patagonia, Argentina). Tracks are longer than w...

Sea anemones (Actiniaria) are among the rarest of recognized fossil organisms, even rarer than jellyfish. Here we demonstrate that most abundant in Pennsylvanian Mazon Creek Lagerstätte Illinois, Essexella asherae, is an infaunal or semi-infaunal anemone. redescribed based on a taphonomic analysis thousands specimens, as well associated medusae and trace fossils. Specimens (also known ‘blobs’) ...

A detailed ichnological analysis has been conducted, for the first time, of Arenazzolo and Trubi formations Caltanissetta Basin in Sicily. Aim this is to evaluate paleoenvironmental changes affecting macrobenthic tracemaker communities during re-flooding Mediterranean at end Messinian Salinity Crisis. The uppermost Formation characterized by a scarcity trace fossils, probably related high energ...

Nineteen ichnotaxa, together with algal and invertebrate remains, various pseudo-traces sedimentary structures are described from the Torneträsk Formation exposed near Lake Torneträsk, Lapland, Sweden, representing a marked increase in diversity of biotic traces recorded this unit. The “lower siltstone” interval contains mostly simple pascichnia, fodinichnia domichnia burrows trails low-energy ...

Abstract The Sierra de las Cabras (Lat. 38° 28′ 53″N, Lon. 1° 24′ 52″W) is an exceptional ichnofossil site of late Miocene age, located in the Prebetic ranges near town Jumilla (Murcia Province, SE Spain). contains abundant vertebrate ichnofauna preserved carbonate facies that were deposited a semi-arid wetland system with shallow ponds and marshes. includes diverse mammal footprints trackways,...
