A New Ichnogenus for Crustacean Trace Fossils from the Upper Miocene Camacho Formation of Uruguay
Year: 2004
Type: article
Abstract: Maiakarichnus currani ichnogen. et isp. nov. is a crustacean trace fossil from the Upper Miocene Camacho Formation of Uruguay. This trace fossil is a subspherical chamber preserved in full relief, with numerous thin shafts radiating in a stratigraphically upward direction mainly from its upper part and from the sides. In the Camacho Formation it can be found intergrading with Ophiomorpha and Thalassinoides. Previous (unnamed) findings of similar material are only from the Pamlico Morphostratigraphic Unit (Pleistocene) of North Carolina; these have been interpreted as callianassid brood structures. In this paper we also interpret Maiakarichnus as a brood structure of callianassid origin based on its association with Thalassinoides and Ophiomorpha.
