stratigraphy

The ICS international chronostratigraphic chart (v2022/2).

datasets

Datasets for teaching quantitative approaches and modeling in
archaeology and paleontology. This package provides several types of
data related to broad topics (cultural evolution, radiocarbon dating,
paleoenvironments, etc.), which can be used to illustrate statistical
methods in the classroom (multivariate data analysis, compositional
data analysis, diversity measurement, etc.).
