An article published in the journal “Nature” reports a study on a trilobite fossil of the species Bohemolichas incola dating back to around 465 million years ago, in the Middle Ordovician period, which reveals the contents of its guts in the last meal that occurred before its death. A team of researchers subjected the fossil in an extraordinary state of preservation to a sophisticated synchrotron microtomography that made it possible to create a 3D reproduction that also shows the contents of its intestinal tract. That revealed that this trilobite ate some marine invertebrates such as ostracods, bivalves, and echinoderms.
