Download PAST (PAlaeontological STatistics) – Data Analysis Package for Paleontology

PAST (PAlaeontological STatistics) is a data analysis package aimed at paleontology. Inspired by PALSTAT, it includes common statistical, plotting and modeling functions. It features a spreadsheet-like data entry form, and supports both interactive user interface and scripting.
