Zoophycus.

Zoophycos is a well-known trace fossil common throughout the Phanerozoic. Paleozoic forms show important differences in morphology and habitat distribution with respect to the Jurassic, Cretaceous, and Cenozoic ones. Therefore, Early-Middle Triassic is considered a crucial time-span for the understanding of the evolution of this trace fossil. So far, Early Triassic Zoophycos is unknown and ...Now I'm leaning towards Zoophycos. Can anyone confirm if it is zoophycos, and help with the morphology of this specific find? I'm under the impression that zoophycos morphology changed throughout the ages, and I'm trying to reverse ID the age of rocks I found it in since the geological maps of my area are extremely vague and lack detail.in turn, are cut by large, well-developed Zoophycus b ur-rows that penetrated down through 30–50 cm of sedi-ment. As indicated by the geochemical criteria, Kapp.The Zoophycos ichnofacies observed within the middle unit of the Río Mayer Formation (sections 2 and 4) mainly comprises Zoophycos and Chondrites associated with some Bergaueria specimens (Fig. 4 A). The middle unit developed between the Valanginian and Hauterivian in this region.

One of the most phenomenal events in the history of Phanerozoic life was the end-Cretaceous (K-Pg) mass extinction, occurring 66.04 Ma ago (Vandenberghe et al. 2012; Husson et al. 2014 for recent calibrations), an event that has been important for the subsequent evolutionary and ecological history of the continental and marine biota. …
