Aspidaeglina is an extinct genus from a well-known class of fossil marine arthropods, the trilobites. It lived during the early part of the Arenig stage of the Ordovician Period,^[1] a faunal stage which lasted from approximately 473 to 470 million years ago.

A. miranda is known from the Lower Ordovician of the Czech Republic (Arenig, Klabava Formation).^[2]
A. striata occurs in the Lower Ordovician of China (Pagoda Formation of southwestern Shaanxi).^[3]
