Paleontologists from the Faculty of Science, Charles University in Prague, and their colleagues describes a 465-million-year-old trilobite with preserved gut contents in a new study. The research was published in Nature.
This unique fossil, three-dimensionally preserved in a so-called Rokycany ball, was found more than a hundred years ago. But it has revealed its secrets only now, thanks to the cutting-edge imaging methods of synchrotron tomography. The research fills a fundamental gap in our understanding of trilobite ecology and their role in Paleozoic ecosystems.
But it was not until the beginning of the 21st century that paleontologists realized that the bits of shells visible in the peeled-off median axis of the trilobite's trunk could represent preserved digestive tract contents. At that time, it was impossible to examine them without destroying the rare fossil.
