Beyler Dam (Cretaceous of Turkey)

Where: Devrekani, Turkey (41.7° N, 33.8° E: paleocoordinates 34.3° N, 29.5° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Davutlar Formation, Late/Upper Maastrichtian (70.6 - 66.0 Ma)

• "The Davutlar formation lies conformably on the Middle–Upper Maastrichtian Tomalar formation and is conformably overlain by the Upper Paleocene–Eocene Gürleyikdere formation."

• bed-level stratigraphic resolution

Environment/lithology: marginal marine; lithified, nodular, silty, sandy limestone

• "The Davutlar formation was deposited in a near-shore environment with sediment coming from a recycled obduction-collision orogenic provenance."
• "The Davutlar formation consists of silty to sandy limestones, marls, and sandstones. It includes a well-exposed K/T boundary (KTB), one of the few in Turkey. Just below the KTB is a fossiliferous level very rich in invertebrate macrofossils (ammonites, inocerams, echinoderms, corals, crabs) and microfossils (calcareous nannoplankton, planktonic and benthic foraminifera, ostracods). The mosasaur specimen comes from this level. According to petrographical analysis, these sandstones correspond to greywacke, subgreywacke and litharenite."

Size class: macrofossils

• "remains of a large skull, including two maxillary fragments (right and left) with teeth, a partial left jugal, several isolated teeth and indeterminate bones, probably from the palate, preserved in several blocks as part and counterpart."
