The Middle Silurian in Paleozoic spanned from 428 to 423 millon years ago. The explanation in brackets is the ages they lived in extinct species. Note that Mya is million years ago. For example, "48.6～40.4 Mya" shows a range between 48.6 and 40.4 million years ago. The italic and bold figures, e.g. 488, show out of the range. The time range is shown in the Geological Time Table. The followings are a part of the Evolutionary Tree.

Redlist Categories & Criteria - Extinct, Extinct in the Wild, Critically Endangered, Endangered, Vulnerable, Others
The italic shows endemic species. * after the name shows subspecies. ' after the name shows family or genus.

shows maga species or largest of the family.

shows rare and interesting species.

shows colorfull or beatiful species.

shows venomous or harmful species.
Great Dying①,②,③,④,⑤ are Ordovician–Silurian (450～440 Mya), Late Devonian (375～360 Mya), Permian–Triassic (260～253 Mya), Triassic–Jurassic (205 Mya), Cretaceous–Tertiary (65.5 Mya) extinction event. It means that the species survived the Great Dying (GDying).
