the history of life on earth is largely reconstructed from time-averaged accumulations of fossils. a glimpse at ecologic-time attributes and processes is relatively rare. however, the time-sensitive and predictability of echinoderm disarticulation makes them model organisms to determine post-mortem transportation and allows recognition of ecological-time data within paleocommunity accumulations. unlike many other fossil groups, this has allowed research on many aspects of echinoderms and their paleocommunities, such as the distribution of soft tissues, assessment of the amount of fossil transportation prior to burial, determination of intraspecific variation, paleocommunity composition, estimation of relative abundance of taxa in paleocommunities, determination of attributes of niche differentiation, etc. crinoids and echinoids have received the most amount of taphonomic research, and the patterns present in these two groups can be used to develop a more thorough understanding of all echinoderm clades (1)
the rise of the internet and mobile telecommunications has created the possibility of using large datasets to understand behavior at unprecedented levels of temporal and geographic resolution. online social networks attract the most users, though users of these new technologies provide their data through multiple sources, e.g. call detail records, blog posts, web forums, and content aggregation sites. these data allow scholars to adjudicate between competing theories as well as develop new ones, much as the microscope facilitated the development of the germ theory of disease. of those networks, twitter presents an ideal combination of size, international reach, and data accessibility that make it the preferred platform in academic studies. acquiring, cleaning, and analyzing these data, however, require new tools and processes. this element introduces these methods to social scientists and provides scripts and examples for downloading, processing, and analyzing twitter data (1)
