greenalgae: Green algae diversity since the Jurassic

Description

Green algae fossil diversity since the Jurassic

Usage

data(greenalgae)

Details

Green algae fossil diversity since the Jurassic compiled from the Neptune Database (Lazarus, 1994) and Paleobiology Database (https://paleobiodb.org/). Diversity curves are estimated at the genus level using shareholder quorum subsampling (Alroy, 2010) at two-million-year bins. The format is a dataframe with the two following variables:

age

a numeric vector corresponding to the geological age, in Myrs before the present

greenalgae

a numeric vector corresponding to the estimated green algae change at that age
