Lipeón Formation


The Lipeón Formation is a Telychian to Pridoli geologic formation of southern Bolivia and northwestern Argentina. The formation comprises sandstones and siltstones. Plant fossils comprising rhyniophytes are scattered throughout, with some abundant concentrations on micaceous bedding plains. The fossil flora is the oldest of South America. Also present were quite diverse small, irregularly branching fragments possibly the tips of algae
such as Buthotrephis or Hungerfordia.
