Resumen:
We report the first liverwort fossils from the Arroyo Totoral Formation and discuss their importance for the fossil record of the group, their paleoecology, and compare them with coeval South American occurrences.The fossil material is preserved as a compression and consists of thalloid plant remains associated with a gymnosperm branch. The delicate thallus differentiated into wings and midrib suggests that the fossil is a simple thalloid liverwort. The lack of reproductive structures and of unequivocal cellular detail constrains the taxonomic assignment to Hepaticites.
