There may be two generations of borings with the bryozoan younger than one and older than the other. I hope we can find similar boring/encruster combinations in the Cretaceous of Israel next week.

However in the upper center of the sample the bryozoan bridges the borings in several cases which would suggest it arrived after the sponge had left.
