ABSTRACT Aim Arthropods are under‐represented in paleoecological studies but critical agents ecological processes. Despite rigorous documentation of diverse arthropod assemblages from ancient rodent (or paleo) middens worldwide, their use for studying diversity has stalled recent decades. Here, we review published to identify how paleomidden arthropods can be leveraged address significant questions ecology and synthesise spatiotemporal trends diversity. Location Global with a focus on the Americas. Time Period From ~40,000 100 years before present. Major Taxa Studied Fossil preserved paleomiddens. Methods We identified four primary objectives that advanced using fossils: reconstruction biodiversity, elucidation mechanisms processes driving range shifts, incorporation into trophic webs, assessment adaptive responses changing environments. Results 20 papers reporting remains, which 14 provided data suitable quantitative analyses. Although no differences community were found across broad geographic regions, substantial structure observed. In North America, also detected decline 10 5 ka BP, driven primarily by absence high‐diversity during this period. Main Conclusions Paleomidden remain an underutilised resource improve inferential scope research gradients. Collaboration between paleo‐ neoecologists could help expand sampling modern communities, particularly those associated paleomiddens, create high‐resolution datasets spanning important periods biogeographical history. will fundamental component understanding biodiversity changes past, present, future.
