Arachnids were among the early land animals to successfully establish themselves in terrestrial ecosystems, and fossils such as Maiocercus provide valuable insight into the evolution and diversity of early arachnid groups. Exceptional preservation within coal bearing sediments makes these fossils important records of ancient forest ecosystems.
