Yayla section (Cretaceous of Turkey)

Where: Turkey (41.1° N, 28.9° E: paleocoordinates 24.4° N, 26.5° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Davutlar Formation, Campanian (83.6 - 72.1 Ma)

Environment/lithology: marine; lithified, yellow, sandy limestone and lithified, gray, yellow marl

• The lower part of the succession is made

•up of thick-bedded, yellow sandy limestone interbedded

•with thin, yellow marl and limestone. The upper two-thirds

•of the succession is composed of grey marl with thin lime-

•stone and sandy interbeds. The succession exposed is about

•90 m thick; the upper, highly fossiliferous succession yield-

•ing the ammonites and inoceramids is about 35 m thick.

Size class: macrofossils
