文摘

•: The infilling of trace fossils from the K–Pg boundary transition has been analyzed.
•: Geochemical proxy evidence material from the ejecta layer infilling trace fossils.
•: Trace fossils distribution evidences a rapid recovery of the macrobenthic community.
•: Bioturbational disturbance should be considered for the K–Pg event reconstruction.
