In an astonishing revelation, scientists have uncovered the ancient fossil of a previously unknown earwig species named *Apachyus madseni* in the Fur Formation of Mors, Northwestern Denmark. This remarkable find marks the first recorded fossil of the mysterious earwig family, Apachyidae, believed to have flourished around 55 million years ago during the Early Eocene epoch.

The newly classified species, *Apachyus madseni*, measures nearly 1.9 cm (0.75 inches) in length. Paleontologists describe this ancient insect as part of the Dermaptera order, commonly referred to as earwigs. Today, the living relatives of this family are predominantly found in regions spanning central and southern Africa, India, Southeast Asia, and Australia, where they are often recognized by their flat bodies and striking coloration.

Jan Audun Rasmussen, a paleontologist at Museum Mors, explained the significance of this finding. "The current species of Apachyidae, which include 15 species across two genera, shows that there has been a considerable range expansion for this family over time," he stated. "The current distributions don't provide an accurate picture of their historical presence."

The fossil was remarkably well-preserved, offering vital clues about its paleoenvironment. The deposits of the Fur Formation, where the fossil was discovered, were once part of a seabed, suggesting that Denmark, about 55 million years ago, was enveloped in a subtropical to near-tropical climate—a stark contrast to its current landscape.

Through the study of sediment layers, researchers hypothesize that *Apachyus madseni* may have been adrift in the sea after being transported from tree bark, likely originating from nearby Sweden or Norway. Dr. Rasmussen expressed that it is unsurprising to find such a creature so far north, given the warmer conditions that existed in ancient Denmark, as indicated by an assortment of fossils—including fish, birds, insects, and vegetation—from this time.

This extraordinary discovery pushes boundaries in understanding the biogeography of earwigs and their evolution. Findings have been published in the journal *Palaeoentomology*, shedding light on Earth's history and the ecological aspects of the Eocene epoch.
