Toragnostus

Toragnostus is a genus of trilobites restricted to the late Middle Cambrian.

Its remains have been found in the United States, Greenland, Denmark, China, Sweden, the Russian Federation, and Kazakhstan.

Like all Agnostida, Toragnostus is diminutive, with the headshield (or cephalon) and tailshield (or pygidium) of approximately the same size (or isopygous) and outline.

The central raised area of the cephalon (or glabella) is outlined at the rear, narrow and tapering forward.

It carries an elongated median node, clearly in the front half of the cephalon.
