FIG. 4. — Geochronology dataset of La Venta site. Reinterpretation of the magnetostratigraphy chrons of Flynn et al. (1997) is located on the bottom followed by the model age, the CS, and the stratigraphic position of each sample. Geochronology sample references: Takemura et al. (1992): 002, 003, and 004; Takemura & Danhara (1985): LV8, KS4 and LV13; Flynn et al. (1997): JG-R89-2, JG-R89-3, and JG-R88-2; Anderson et al. (2016): Z1, Z2, Z3, Z4 and Z5; Cadena et al. (2020): 46311(UR-01) and 46312 (UR-02); Montes et al. (2021): SEL-02; this work: 44017, 44011, TVV-04, and TVV-01. The stratigraphic position of geochronology samples was estimated by literature reported information, graphic correlations, and the cartography of Montes et al. (2021). Updated polarity chrons is based on our age model and Hilgen et al. (2012).
