Trace of the day: Nereites

The fossil record preserves abundant horizontal traces with sediment pads. These traces, known as Nereites , have tradistionally been attributed to worm tracemakers, but then researchers pictured horseshoe crabs leaving Nereites-like traces.

I also documentes Nereites-like traces made by arthropods (hermit crabs) in the Adriatic sea… and now there is a Thyrrenian example!
