Amphoraspis

Amphoraspis stellata is an amphiaspidid heterostracan in the family Amphiaspididae.

Its fossils are restricted to early Devonian-aged marine strata of the Taimyr Peninsula, Siberia.

A. stellata, as with all other amphiaspidids, is thought to have been a benthic filter feeder that lived on top of, or buried just below the surface of the substrate of hypersaline lagoon-bottoms.

So far, A. stellata is known from at least one, 14 centimeter-long, broad and dorsally rounded cephalothoracic armor that is shaped vaguely like, as the generic name suggests, an amphora.

The external surface of the armor has a unique micro-ornamentation of a pattern of star-like shapes.
