Bivalve shell Trace Fossil Burrow
Part body fossil, part trace fossil
This is quite an unusual specimen; a bivalve shell preserved inside its burrow. The shell is a ‘body fossil’, while the burrow is a ‘trace fossil’. Finds like this can be extraordinarily useful in that they link the two together as being the result of the same animal.
