Updating a Paleogene magnetobiochronological time scale through graphical integration.

Area of Science:

• Paleontology
• Geochronology
• Stratigraphy

Background:

• Accurate paleoecological studies require precise age constraints using integrated time scales.
• Existing time scales can be limited for comparing data across different locations or assessing long-term evolutionary events.
• The Paleogene period is crucial for understanding evolutionary responses to significant climate variability.

Purpose of the Study:

• To update the Paleogene magnetobiochronological time scale.
• To provide a standardized data structure for analyzing paleoecological data in MATLAB.
• To enable detailed analysis of taxonomic group trends and evolution during the Paleogene.

Main Methods:

• Graphical correlation of new age models with existing magnetobiochronological data.
• Integration of calcareous nannoplankton and planktonic foraminiferal biozones from various authors.
• Development of an Excel file structure for data plotting in MATLAB.

Main Results:

• An updated Paleogene magnetobiochronological time scale was established.
• A versatile Excel file structure was proposed for plotting diverse paleoecological data.
• The methodology facilitates the analysis of long-term taxonomic trends and evolutionary patterns.

Conclusions:

• The updated time scale enhances the comparability of paleoecological data.
• The proposed data structure simplifies the analysis of Paleogene evolutionary dynamics.
• This work provides a valuable tool for studying climate variability impacts on ancient life.
