Centipedes and Millipedes
House Centipede
Centipedes and millipedes are some of the oldest land animals known from the fossil record. The oldest fossil land animal is a millipede about 428 million years ago. This fossil millipede has spiracles, evidence that millipedes at this early date breathed air and were fully terrrestrial. Centipede fossils date to the same time period, about 418 million years ago.
