The Tremadocian‐to‐Floian siliciclastic deposits of the Shirgesht Formation in the Kalmard Block of central Iran show abundant occurrences of the mid‐tier Trichophycus venosus, a common ichnotaxon in the archetypical Cruziana ichnofacies. This trace fossil records a considerable increase in exploitation of offshore infaunal ecospace in comparison with older formations. Here, Trichophycus is relatively...
New occurrences of Estrellichnus jacaensis in the deep‐marine turbidite deposits of the Eocene Hecho Group (Fiscal, Huesca, NE Spain) are described. Most of them include specimens preserved as ‘urban fossils’ located in several villages of the south‐central Pyrenees. Well‐preserved morphological features of the new specimens studied and their interactions with accompanying ichnotaxa allow reinterpreting...
About 200 Zoophycos specimens, including 90 specimens studied in detail, have been analysed in the continuous Upper Cretaceous–Lower Miocene pelagic sedimentary type sections of the Gubbio area (the Contessa Highway, Contessa Quarry and Bottaccione sections, Northern Apennines). The sediments are reddish to grey limestones and marls of the Scaglia Group and marls with volcaniclastic deposits of the...

The tubular trace fossil Nummipera eocenicaHölder 1989 occurs in a single stratigraphical horizon in Eocene nummulitic limestones of the Tatra Mountains, Poland. The wall of N. eocenica is built of Discocyclina...
Kędzierski, M., Rodríguez‐Tovar, F.J. & Uchman, A. 2011: Vertical displacement and taphonomic filtering of nannofossils by bioturbation in the Cretaceous–Palaeogene boundary section at Caravaca, SE Spain. Lethaia, Vol. 44, pp. 321–328.
At the Caravaca section, SE Spain, the position of the Cretaceous–Palaeogene (K–Pg) boundary is well‐defined, with multidisciplinary datasets from a thin rusty...
