ammonites
Asher-Atlit-1 Borehole, reef facies, Haifa (Triassic of Israel)

Also known as Reef 2787

Where: Israel (32.7° N, 34.9° E: paleocoordinates 7.2° N, 27.7° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Norian (221.5 - 205.6 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified reef rocks

• The reef facies may correspond to platform rim biolithite reefs, or to ramp-like oolitic shoals and patch reefs. Back-reef environments are characterized by algal-foraminiferal facies with coated grains, oncoids and foraminifera, and a grapestone facies. Cummulative thickness of reef facies about 340 m.

Size classes: macrofossils, mesofossils, microfossils

Collection methods: core, peel or thin section,
