Also known as Sakamena River Valley; Morondava Basin
Where: Tulear, Madagascar (24.0° S, 44.4° E: paleocoordinates 53.0° S, 25.2° E)
• coordinate estimated from map
• local area-level geographic resolution
When: Lower Sakamena Formation (Sakamena Group), Lopingian (259.9 - 252.2 Ma)
• "Recent work by Goubin (1965) on spores and pollen from numerous localities in Madagascar divides the Lower Sakamena into three zones, all of which are indicated as Upper Permian. The terrestrial vertebrates occur in the uppermost of the three zones recognized by Goubin, and so at the very top of the Permian." (Carroll, 1981 p. 318)
• member-level stratigraphic resolution
Environment/lithology: terrestrial; lithology not reported
Size class: macrofossils
Preservation: mold/impression, concretion
