The small mammal fauna (Marsupialia and Rodentia) from Araras ravine, a Quaternary deposit in northeastern Brazil, and their paleoclimatic significance for South American paleoenvironments

Key Points

• The analysis indicates that the small mammal fauna reflects significant paleoclimatic changes in South America.
• Key evidence includes fossil findings that provide insights into regional climate shifts during the Quaternary period.
• Observational analysis of fossils was conducted within the Araras ravine to determine faunal diversity and distribution.
• Understanding these changes highlights the importance of small mammals as climate indicators and their role in reconstructing past environments.
