Published in 2017 at "Geobios"

DOI: 10.1016/j.geobios.2016.11.002

Abstract: Abstract Well-exposed fossiliferous Upper Cenomanian–Lower Turonian marine sedimentary rocks are present in west-central Jordan. Ammonites serve as an important faunal marker for this interval and can be used to subdivide the Cenomanian–Turonian transition into two… read more here.

DOI: 10.1016/j.palaeo.2019.109238

Abstract: Abstract The Cenomanian/Turonian (C/T) boundary interval, spanning the upper part of the Sarvak Formation in the Zagros Basin (Izeh Zone), has been studied to determine the timing and the possible cause of biotic turnovers, coinciding… read more here.

Published in 2019 at "Moscow University Geology Bulletin"

DOI: 10.3103/s0145875219040082

Abstract: Cenomanian–Turonian organic-rich clays deposited under periodic anoxic conditions in the basins of that time are recorded in carbonate sections. Cenomanian–Turonian boundary deposits were studied in the Biyuk-Karasu River section (Central Crimea). Dark organic-rich clays were… read more here.
