The ichnological importance and interest of the Geological Museum of Lisbon collections: Cladichnus lusitanicum in continental facies from the Lower Cretaceous of the Lusitanian Basin (Portugal)

Description

The revision of the classic collections of trace fossils housed in the Geological Museum of the former Geological Survey of Portugal is bringing new information to well established ichnogenera. Through the revision of the type material of Taenidium lusitanicum Heer, 1881 and other specimens housed in the Geological Museum of Lisbon and the National Museum of Natural History and Science we reinstate the ichnospecies Cladichnus lusitanicum (Heer). This is the only ichnospecies of Cladichnus occurring in environment typical from the Scoyenia ichnofacies in otherwise typical turbidite forms.
