Pabulite Kill Leftover Evidence and the Food Chain
The focus on the food chain is not just because the predator got preyed upon, but also because of another potential evolutionary facet.
All cephalopods, in general, have tough rostra or beaks that are hard, pointed and difficult to digest. Fossils from the same period of marine crocodiles and predatory fish, and their stomachs, point to the fact that they were not discerning eaters, gobbling everything down, even the hard beaks.
This has been gauged from the remains of a fossilized shark (another
Hybodus hauffianus ), from the early Jurassic, also found in Germany. It had a stomach full of undigested belemnite beaks, which likely caused its premature and untimely death.

The evolutionary biologist and polymath J.B.S. Haldane is said to have remarked that “The universe is not only queerer than we imagine but queerer than we can imagine.” And one of those many queer things is that there are more species of beetles than any other kind of animal on our planet. This queer fact also apparently did not escape Haldane’s notice and repartee. Replying to theologians who inquired if there was anything that could be concluded about the Creator from the study of creation, Haldane is said to have quipped, “An inordinate fondness for beetles.”
