Data and code for a high-resolution summary of Cambrian to Early Triassic marine invertebrate biodiversity

Data compilation and standardization were conducted through the
Geobiodiversity Database from 2013 to 2017. The raw dataset contained
266,110 local Cambrian to Triassic records of 45,318 taxonomic units from
3,766 published stratigraphic sections. These were collected from all
major Chinese tectonic plates. The authors spent three years verifying the
taxonomic assignments into a consistent paleontological taxonomic
classification system. Identifications to genus or higher taxonomic ranks
were omitted. All non-marine fossil groups (e.g., plants, vertebrates,
pollen, spores) were also removed. Species recovered from only a single
locality were removed after a few test calculations in order to partially
standardize the sampling and research efforts and avoid the
"monograph effect". The final dataset retained after all
standardization procedures included 116,060 local records of the
stratigraphic ranges of 11,268 species in 3,112 published stratigraphic
sections.  The CONOP.SAGA program was designed for
high-performance computing of geological time scale and biodiversity
analysis in 2017. We designed a special hybrid algorithm that combined
simulated annealing and a genetic algorithm to overcome the limitations of
classic CONOP program designed by Pete Sadler.
