Resumen


Los clastos carbonatados de la Formación del Monte Wegener proporcionan evidencias sedimentológicas, diagenéticas y paleontológicas de la destrucción y resedimentación de un registro carbonatadoo cámbrico oculto/no conocido en aguas someras de la región de Coats Land en la Antártida. Este mosaico incompleto podría jugar un papel clave en las comparaciones y correlaciones bioestratigráficas entre el registro cámbrico de las Montañas Transantárticas, el bloque Ellsworth-Whitmore y la Península Antártica del continente antártico. Además, representa un registro clave en las futuras reconstrucciones paleobiogeográficas de Gondwana meridional basadas en asociaciones de arqueociatos.

Palabras clave
