Huge, cone-shelled cephalopods and massive trilobites didn’t evolve because of simple causes such as an abundance of oceanic oxygen or dips in ocean temperature.

Trilobites that played host to other organisms had been reported before, but Key and his colleagues focused on a large sample of specimens from the trilobite-rich shales around southern Ohio.

Because Ceraurus trilobites had spiny shells, they folded more than they rolled. “It’s a lot more like a taco than a perfect ball,” Ms. Losso said.

After dinosaurs, trilobites are perhaps the most recognizable fossil animals (SN: 9/27/23).They proliferated in the ocean for about 270 million years before going extinct at the end of the ...
