dc.descriptionStelloglyphus llicoensis isp. nov. is a large radial, discoidal to ellipsoidal trace fossil with a central shaft and single to bifurcating branches radiating from different levels. A 30 m thick measured section of the Ranquil Formation at Punta Litre contains an associated trace fossil assemblage including Zoophycos, Chondrites, Phycosiphon, Nereites missouriensis, Lockeiasiliquaria, Psammichnites(?), Parataenidium,Ophiomorpha, and Rhizocorallium, some of which reworked the Stelloglyphus traces. The sedimentology, together with micro- and macrofossils and the associated trace fossil assemblage, suggest that the succession was deposited in an outer continental shelf to slope environment in subtropical to tropical waters.en-US

Un perfil estratigráfico de 30 m medido en la Formación Ranquil en Punta Litre contiene una asociación de trazas fósiles asociadas que incluye Zoophycos, Chondrites, Phycosiphon, Nereites missouriensis, Lockeia siliquaria, Psammichnites(7), Parataenidium, Ophiomorpha, y Rhizocorallium, algunas de las cuales retrabajaron las trazas de Stelloglyphus. La sedi-mentología, junto con los micro- y macro fósiles y la asociación de trazas fósiles, indican que la sucesión fue depositada en la parte exterior de la plataforma continental hasta el talud continental en aguas subtropicales a tropicales.es-ES
