Where: Fianarantsoa, Madagascar (22.6° S, 45.4° E: paleocoordinates 52.4° S, 27.8° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Lower Sakamena Formation (Sakamena Group), Lopingian (259.9 - 252.2 Ma)
• "Locally, the top of the Permian has been recognized by a prominent nodular layer, above which the nature of the sedimentary record is indicative of the Middle Sacamena Formation, dated throughout the island as Lower Triassic. According to Germain, the aquatic reptiles come from just below this horizon. The spore and pollen flora confirms the Upper Permian age for the beds containing the fossil reptiles." (Carroll, 1981 p. 338)
• bed-level stratigraphic resolution
Environment/lithology: paralic; fine-grained, concretionary, sandy shale
