What evidence do living organisms leave behind in rocks?

'Trace fossils - burrows or borings' Living creatures often leave behind evidence of their activity in rocks, even if their actual remains are not found as body fossils. Clues may be obtained from living examples, which we can study in their modern habitats.

In this activity, pupils are invited to apply previously learned observations about the features of modern bivalve shells to the fossil record.
