The taxonomic treatment of trace fossils needs a uniform approach, independent of the ethologic groups concerned. To this aim, trace fossils are rigorously defined with regard to biological taxa and physical sedimentary ...

The ichnospecies Cuniculonomus parallelus Givulescu, 1984 and Stigmellites serpentina Kozlov, 1988 arerecorded for the first time in Argentina and the new ichnospecies Cuniculonomus saltensis n. ichnosp., Stigmellites ...

The morphology of fossil footprints is the basis of vertebrate footprint ichnology. However, the processes acting during and after trace fossil registration which are responsible for the final morphology have never been ...

The ichnotaxobases previously used to classify avian-like footprints, at the ichnogeneric, ichnospecific, and ichnofamily level, are varied and contrasting. Consequently, an agreement on the most adequate taxobases to use ...

Detailed descriptions of Nereites are uncommon. In this work, Nereites are thoroughly described from tidally influenced and wave dominated deposits in the Cretaceous of the Neuquén Basin (northern Patagonia). These Nereites ...

This contribution undertakes a comprehensive revision, lacking until now, of all the ichnotaxa attributed to fossil bee cells, one of the most common traces in paleosols. These ichnotaxa are morphologically related to ...

Fluidization, a special case of liquefaction, is a physical process occurring in unconsolidated, water-saturated, sediments that can be verified in insect constructions in soils. Behavioral analysis of the bees Ptilothrix ...

The new ichnospecies Cubiculum levis is described as a bowl-shaped bioerosion trace fossil in dinosaur bone from the Upper Cretaceous of western Argentina. The systematic description is based on specific ichnotaxobases for ...

The female Mygalomorphae spiders are sedentary and long-lived organisms that spend most of their lives inside their burrows. Neoichnological studies provide relevant information that can help the recognition of these ...
