Trusheimichnus New Ichnogenus From the Middle Triassic of the Germanic Basin, Southern Germany
Abstract:The proposed new ichnogenus Trusheimichnus n. ig., is a new name for forms hitherto assigned to Arenicolites . The trace fossil occurs in marine upper Middle Triassic limestones. A restudy of type material of Arenicolites franconicus Trusheim, 1934 revealed that the burrows are no U-burrows but irregular tubular structures that terminate in a small oval or bulbous chamber. Associated with the tubular structures are conical to lunate-shaped epichnial mounds.
