Potencial de correlación estratigráfica de los paleopasciquínidos del Ediacárico

For more than forty years, palaeopascichnids represented an enigmatic group of macroscopic fossils, which are characterised by substantial differences in preservation leading to no consistent diagnosis for these organisms. Numerically abundant palaeopascichnid fossils are globally distributed in Ediacaran sequences of the East European Platform, Avalonia, South China, Siberia and Australia. In light of new perspective to reanimate the ‘Vendian’ as a formal upper series of the Ediacaran System, Palaeopascichnida is probably the only Ediacaran fossil group whose stratigraphic range spans almost the entire ‘Vendian Series’. Furthermore, it has been considered that palaeopascichnids are among the oldest known macro organisms with an agglutinated skeleton; its presence puts emphasis on this group in terms of Ediacaran biostratigraphy and geological correlation and paves the way for the reexamination of other skeletal palaeopascichnid-like fossils.
