- •
Trilobite Rusophycus traces are found intersecting vermiform burrows.
- •
Rusophycus trace size is positively correlated with intersected worm burrow size.
- •
Intersected vermiform burrows are significantly smaller than non-intersected burrows.
- •
Low angle attacks occur more frequently than expected due to random chance.
- •
Paired Davis Shale trace fossils may directly record predatory behavior.
