Data of fossils and sections of the Geobiodiversity Database (GBDB)

Geobiodiversity database (GBDB, www.geobiodiversity.com) is a comprehensive stratigraphic and palaeontological database and was started in 2006. It is geological section-based and include data of over 26 500 geological sections and over 114 000 fossil taxa. The stratigraphic data in the GBDB are based on those published in Chinese literature since 1920s. By November 2020, all stratigraphic horizons and nearly all published geological sections can be searched and browsed in the GBDB. The GBDB fossil occurrence data are included in the stratigraphic records and can be queried and outputted. The palaeontological data are linked to the fossil collections from individual geological sections and borehole cores. The data include taxonomy (species, genus, family, order, class and division), major group, synonym (opinion data with different authors) and description (key features). Most fossil collections and occurrences of all sections from China are included in the GBDB. Subsequent authors in further study amended a portion of fossil taxa from these sections. In this way, there are also plenty of opinion data in the GBDB. The GBDB was designed to facilitate regional and global scientific collaborations focusing on palaeobiodiversity, systematics, palaeogeography, palaeoecology, regional correlation, and quantitative stratigraphy
