Pratt said the worm tunnels ranged in size from about a millimetre to larger than a centimetre. Researchers have since revisited the site to collect "hundreds and hundreds and hundreds of pounds" of samples over the years, Pratt said, but it was only recently that he decided to scan the rocks and digitally enhance the images. 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. Despite much research, however, paleontologists do not know the exact nature of the animals that left these fossilized burrows.
