Trace fossil borings

Bored nodule!

Flat nodules like this probably stood as pedestals on the seafloor. These nodules formed as calcium-rich mud which hardened into limestone. Then, a period or erosion took place which left them exposed for some time. As a result, both the undersides and the upper surfaces were bored into by creatures.
