Where: Majunga, Madagascar (17.5° S, 45.3° E: paleocoordinates 22.3° S, 24.0° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Kandreho Formation, Toarcian (183.0 - 175.6 Ma)
• This horizon (D2 of BLAISON 1963) is referred to the middle or late Toarcian, and overlies the Bouleiceras and Spiriferina beds of the early Toarcian.
•This series belongs to the Kandreho Formation (CoLLIGNON et al. 1959), which is the Malagasy equivalent of the Marrat Formation of Saudi Arabia (Jebel Tuwaiq). The corresponding province is known as the Transerythrean Province, which began with the Tuwaiq Gulf (Arkell et al. 1952).
Environment/lithology: lagoonal or restricted shallow subtidal; hardground, ferruginous lithology not reported
•Both levels also yield bivalves from the tidal zone (Trigonia, Modiolus), and sometimes show indications of supratidal and lagoonal environments (with gypsiferous clays); they also contain bone fragments and lignites, and are divided by hard-grounds
