Where: Venezuela (10.4° N, 72.5° W: paleocoordinates 2.4° N, 48.1° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: La Luna Formation, Late/Upper Cenomanian (99.6 - 93.5 Ma)

• Collected from in the lowest part of the exposed section in the La Luna Formation, just above the contact with the underlying Maraca Formation of the Cogollo Group. A Cenomanian age was proposed for rocks of La Luna Formation overlying the Maraca Formation in the Maracaibo Basin (e.g. de Juana et al., 1980, fig. IV-12; Dot et al., 2015, fig. 4). However, other authors (Renz, 1982, fig. 4; Erlich et al., 1999, figs. 3-4) suggested the existence of a regional hiatus in the Sierra de Perijá at the base of La Luna Formation where most of the Cenomanian is lacking. Considering the Sierra de Perijá section suggested by Erlich et al. (1999), the basal section of La Luna Formation in La Luna Quarry could correspond to a late Cenomanian age.
