Really makes you think, doesn't it? Burrow fossils are the remains of burrows - holes or tunnels excavated into the ground or seafloor - by animals to create a space suitable for habitation, temporary refuge, or as a byproduct of locomotion preserved in the rock record.Because burrow fossils represent the preserved byproducts of behavior rather than physical remains, they are considered a kind of trace fossil.

In this image, a large, lined, horizontal burrow is almost 0.8 inches (20 mm) wide. So how did these (insert poop emoji here) manage to fossilize into coprolites? After this, you'll probably never think of a toilet the same way again. These trace fossils are probably the burrows of larval insects made in moist muddy sand, rather than burrows made by earthworms in soils.
