Okay, oops, this appears to be exactly the same story, and it’s not attributed to Reuters. Mea culpa. Actually, society’s to blame.

Yes, trill the bite fantastic.
Orggies? They wuz havin’ orggies?
Okay, people.
Knowing trilobite mating habits like I do, they have to shed the exoskeleton to mate.
Like many other species they find a nice warm backwater enmasse.
After mating the males die and drift away.
The females bury themselves in the mud to gestate.
When the eggs hatch the females die and are entombed in a mass grave.
Can I get that grant NOW?
