Boyar section, level 92-A-40 (Triassic of Spain)

Where: Spain (36.7° N, 5.4° W: paleocoordinates 7.9° N, 5.5° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Carnian (237.0 - 228.0 Ma)

• Dated as Carnian (Upper Triassic) in age on the basis of the contained bivalve, conodont, and pollen assemblages

Environment/lithology: shallow subtidal; lithified limestone

• Although the Boyar Section represents marine environments, and other Triassic marine sharks have been found in several levels through the whole section (pers. observ.), the record of Lonchidion derenzii, sp. nov., is limited to a particular level that represents a very shallow marine platform with close continental influence

Size class: macrofossils

Collection methods: chemical

• Repository: Museum of Geology at the University of Valencia (MGUV)
