rot_ages: Reconstruction ages for palaeogeographic grids

In LewisAJones/PalaeoData: What the Package Does (One Line, Title Case)

Reconstruction ages for palaeogeographic grids

Description

Respective ages for reconstructing the palaeogeographic distribution of spatial grids (1º x 1º) available in this package. Rotation ages are based on the midpoint age of each stratigraphic stage rounded to the nearest million years before present. All Phanerozoic stages are included (0–540 Ma). Midpoint ages are based on the Geological Timescale 2020 and https://stratigraphy.org/timescale/.

Usage

Format

A dataframe with 102 rows and 3 columns:

interval_name

Name of each stratigraphic stage.

mid_ma

Respective midpoint age of each stage in millions of years before present.

rot_age

Rotation age of stage midpoints in millions of years before present.
