| Index of the known fossil insects of the world including myriapods and arachnids. |
| The second or deutocerebral appendage includes the jaw of onychophorans, the raptorial appendage of megacheirans, the antenna of insects and myriapods and the antennule of crustaceans, and the chelicera of chelicerates. |
| Living among these early land plants were a diverse selection of arthropods, including spiders, mites, myriapods and collembolids. |
| Some evidence also suggests the presence of predatory trigonotarbid arachnoids and myriapods in Late Silurian facies. |
| More problematic are the relationships of the four major groups, hexapods, crustaceans, myriapods, and chelicerates. |
| These tiny myriapods generally resemble very small centipedes. |
