Gyrochorte “highways” and their environmental significance in shallow-marine sediments [PDF]

open access: yesActa Palaeontologica Polonica, 2020
The reworking of a trace by a subsequently following organism represents a so-called sequorichnial behavior and leads to formation of a “burrowing highway”. Burrowing highways occur more frequently than assumed in the fossil record.
