This is a cracker as well. At https://phys.org/news/2020-05-fossil-reveals-evidence-million-year-old-s… …. a fossil from the Jurassic coast of Dorset found in the 19th century has had a much closer look (and analysis). It seems to show a squid with a herring like fish in its jaws. In other words it was fossilised and preserved in the act of devouring its prey, a fish. It is said to date from 199 million years ago. On the question of how they were preserved in such a pose it is suggested the fish was too large for the squid and it became stuck in his jaws so the pair of them died together. Alternatively, the squid took its prey down to the sea bottom to avoid attack from its peers or another predator. In doing so it entered into a low oxygen area and suffocated. On the other hand the squid and its mangled prey were caught up in a catastrophe of some kind and instantly fossilised.
