Fugichnia

Fugichnia is an ethological class of trace fossil characterized as "escape burrows" that are formed as a result of organisms' attempts to escape burial in sudden high-sedimentation events like turbidity currents.^[1] The burrows are often marked with chevron patterns showing the upward direction the organisms were tunneling.

Thumb — *Lockeia* from the Dakota Formation (Upper Cretaceous). These are bivalve escape burrows (fugichnia).
