Green algae fossil diversity since the Jurassic
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:
a numeric vector corresponding to the geological age, in Myrs before the present
a numeric vector corresponding to the estimated green algae change at that age
