Giant millipede Arthropleura linked to millipedes with new fossils possibly longer than a car

Its head fossils finally settle what it really was

Researchers say the colossal arthropod Arthropleura—dating to the Carboniferous and early Permian—can now be definitively tied to millipedes thanks to newly discovered head anatomy. The giant likely grew to car-length scales, reshaping how scientists picture ancient land ecosystems and the early evolution of terrestrial life.
