The Fossil Calibration Database-A New Resource for Divergence Dating

Area of Science:

• Paleontology
• Evolutionary Biology
• Bioinformatics

Background:

• Fossil data are crucial for temporal calibrations in divergence dating analyses.
• Formulating accurate calibrations requires integrating phylogenetic, paleontological, and geological evidence, which can be challenging.
• The fossil record is dynamic, necessitating continuous updates to calibration data.

Purpose of the Study:

• To introduce the Fossil Calibration Database, an open-access resource for vetted fossil calibrations.
• To provide the scientific community with reliable data for divergence dating.
• To establish best practices for phylogenetic justification and geochronological constraint in fossil calibrations.

Main Methods:

• Developing an open-access database (http://fossilcalibrations.org) for fossil calibrations.
• Accessioning individual fossil specimens with rigorous phylogenetic and geochronological vetting.
• Establishing the Fossil Calibration Series in Palaeontologia Electronica for peer-reviewed calibration publication.

Main Results:

• The Fossil Calibration Database is now available to the scientific community.
• Calibrations are based on individual fossil specimens and adhere to best practices.
• A publication series ensures a pipeline for peer-reviewed calibrations.

Conclusions:

• The Fossil Calibration Database enhances the accuracy of divergence dating by providing reliable, vetted calibration data.
• This resource simplifies the process of formulating robust calibrations for researchers.
• Continuous updates and peer review will maintain the database's relevance and utility.
