Provides functions and methods for estimating phenological dates (green up, 
  start of a season, maturity, senescence, end of a season and dormancy) from (nearly) 
  periodic Earth Observation time series. These dates are critical points of some 
  derivatives of an idealized curve which, in turn, is obtained through a functional principal 
  component analysis-based regression model. Some of the methods implemented here are 
  based on T. Krivobokova, P. Serra and F. Rosales (2022) <https://www.sciencedirect.com/science/article/pii/S0167947322000998>. 
  Methods for handling and plotting Earth observation time series are also provided.

Stratigraphic ranges of fossil marine animal genera from Sepkoski's
    (2002) published compendium. No changes have been made to any taxonomic 
    names. However, first and last appearance intervals have been updated to be
    consistent with stages of the International Geological Timescale. 
    Functionality for generating a plot of Sepkoski's evolutionary fauna is also
    included. For specific details on the compendium see:
