<< What she found was that the trilobite traces intersected the worm burrows more often than would be expected by random chance. The fossils also show evidence that suggests the trilobites were selective in hunting their prey, preferring smaller worms, and that trilobites attacked their prey at low angles more frequently than expected, improving their chances of grabbing onto and handling their prey >>
