Summary

Descripción general del contenido del recurso.

The ichnogenus Lapispira Lange (originally recognized in the Hettangian of Germany) attained a wide geographic distribution, occurring mainly in Jurassic sediments. The ichnotaxon was recently re-described in Sinemurian-Pliensbachian deposits in southern Mendoza Province (Argentina), and is here newly reported in slightly younger (latest Pliensbachian) deposits of the Mulanguiñeu Formation of Chubut Province. According to recent revisions, the ichnogenus appears to have been mainly environmentally restricted to the shoreface and offshore-shoreface transition zone, being only exceptionally found in offshore tempestites. In Chubut Lapispira bispiralis Lange is accompanied by an abundant euhaline fauna dominated by bivalves, several gastropods and rare ammonoids , and, similarly to what happens in the Neuquén Basin, it is commonly associated to Rhizocorallium isp. El icnogénero Lapispira Lange, originalmente reconocido en el Hettangiano de Alemania, alcanzó una distribución geográfica muy amplia, mayormente en sedimentos jurásicos. Este icnotaxón fue recientemente redescripto en depósitos sinemuriano-pliensbachianos del sur de la Provincia de Mendoza (Argentina), y en este trabajo se registra en sedimentos algo más jóvenes (Pliensbachiano tardío) de la Formación Mulanguiñeu de la Provincia del Chubut. De acuerdo con revisiones recientes, el icnogénero parece haber estado principalmente restringido a ambientes de shoreface y la zona de transición shoreface-offshore, encontrándose sólo excepcionalmente en tempestitas de off-shore. En Chubut Lapispira bispiralis Lange está asociada a una abundante fauna euhalina dominada por bivalvos, algunos gastrópodos y raros ammonoideos y, en forma similar a lo que sucede en Neuquén, está acompañado por Rhizocorallium isp.
