Fossils of largest known arthropod reveal new insights into ancient creature's anatomy

Researchers have discovered two well-preserved fossils of Arthropleura, the largest known arthropod, in France. This marks the first time the creature's head has been documented, revealing features that suggest a closer relationship between millipedes and centipedes. The fossils, dating back over 300 million years, show Arthropleura had characteristics of both modern millipedes and centipedes. This finding challenges previous beliefs about their evolutionary distance and provides new insights into the creature's lifestyle and anatomy. The study also raises questions about Arthropleura's diet and respiratory system. While it likely fed on decaying material, further research is needed to understand its habitat and whether it had amphibious traits.
