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.
