Stratigraphy
| Formation: | Culebra | ||||
| Stratigraphic resolution: | member | ||||
| Stratigraphy comments: Early Miocene (late Aquitanian–early Burdigalian: dated using strontium isotopes to between 21.24 ± 0.44 and 19.12 ± 0.42 Ma; Kirby et al., 2008). These dates are consistent with the estimated ages of the underlying Cascadas Formation (20.93 ± 0.17 Ma; Bloch et al., 2016) and overlying Cucaracha Formation (18.81 ± 30 Ma; MacFadden et al., 2014). | |||||
