These include: 1) finding and describing new fossils in Precambrian strata, 2)
using analytical tools to examine those fossils in order to determine taxonomic affinity,
taphonomy, functional morphology, and paleoecology, 3)
using modern analogs to determine phylogenetic relationships and physiology of early eukaryotes and animals, and 4) combining multiple sources of data to create a timeline of biotic and abiotic events in the Precambrian.
