"What do Giant Fish Eat?"
One of the strangest finds to ever come off Blue Beach is this irregularly-shaped lump of siltstone filled with bones. It was discovered in layers that were part of a deeper-water layer – thin shales with very little bone content. Bones do not accumulate together by normal physical processes in deep water environments, so how did they come together in this jumble? The answer must be that they accumulated together via some kind of biological process.
One suggestion was that it is a coprolite, or, fossilized poo! Further examination showed that the bottom is highly rounded instead of flattened as one would expect of a large, deep-water coprolite.
It is therefore suggested to be a coelolite – the fossil of a complete stomach or intestinal tract with contents still inside fossilized in the process of being digested!
There is only one likely candidate for who this stomach could have belonged to – Letognathus, the big fish whose name means “jaws of death, annihilation, or ruin”.
