Homalonotidae is a family of trilobites that lived from the Ordovician to the Devonian. They are characterised by a shovel-like cephalon (head), and are closely related to the family Calymenidae.[1]

It contains the following genera:[2]

Reconstruction of Trimerus delphinocephalus, the exoskeleton of which was probably fringed with many sensory hairs called Setae.
