Analox[2] is a genus of eodiscinid trilobites belonging to the family Weymouthiidae Kobayashi T. (1943),[3] Order Agnostida (Salter 1864) [4] It lived during the Botomian stage.

[5][6] Type locality for Analox bipunctata is Rasetti's (1966) locality cs-4 in an unnamed limestone Formation which is exposed in several outcrops on a hill (Griswold Farm) about 1 mile southeast of North Chatham, Columbia County, New York State, USA; the faunule is referred to as the Acimetopus bilobatus faunule from one of the most common and characteristic trilobites.

A. bilobatus occurs in association with other Weymouthiidae (Acidiscus, Acimetopus, Bathydiscus, Bolboparia, Leptochilodiscus, Serrodiscus), Calodiscus, several species of Olenellus and Bonnia (Dorypygidae).

[5] Like all Agnostida, Analox is diminutive and the headshield (or cephalon) and tailshield (or pygidium) are of approximately the same size (or isopygous) and outline.

The large lobe behind this furrow (or L1), extends into a massive, broad based spine that points backward and upwards.
