Wormholes

Holes in the pages of  a book that look like they were made by a worm crawling through the pages. The damage is actually caused by insects or insect larvae that have eaten the paper. The image shown is taken from a woodcut currently residing in Amsterdam’s Rijksmuseum dating to the 15th century. The white holes are trace fossils of wood-boring beetles that serve evidence of their behavior printed into old pages, just as dinosaur tracks were printed into the earth.
