Poamay, M-24 (Triassic to of Madagascar)

Where: Toliara, Madagascar (20.3° S, 45.4° E: paleocoordinates 23.1° S, 24.7° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Upper Member (Isalo II Formation), Norian to Norian (228.0 - 174.7 Ma)

• "within the uppermost Malagasy Karoo (upper Isalo II), immediately below the Andafia Limestone, and below overlying post-Karoo strata". Age of locality is very poorly constrained - biostratigraphic evidence suggests either Late Triassic (Norian) or Early Jurassic

• member-level stratigraphic resolution

Environment/lithology: fluvial; white sandstone

• "finely crossbedded well sorted white sandstone"

Size class: macrofossils

Collected in 1997; reposited in the FMNH
