From: The billion-dollar case for sustaining palaeontology’s digital databases
a, The range-through richness of databases by year. b, The origination rate of databases through time, indicating areas of peak activity for novel database development between 1995 and 2005. c, Diversity of databases as a function of years active (that is, database survivorship) showing the loss of >80% of database diversity by 10 years of activity. d, The rolling mean per-capita extinction rate of databases as a function of years active since inception, with peaks at 5, 15 and 25 years of activity.
