Angelacanthus

Angelacanthus acus is a species of Devonian acanthodian from the Waterloo Farm lagerstätte in South Africa. It is the only species in the genus Angelacanthus.

Description

Angelacanthus was described from a near complete whole-bodied impression discovered in 1999 during roadworks cutting the Waterloo Farm lagerstätte. The type specimen of Angelacanthus is approximately 100 mm long and has exceptionally long and thin ribbed spines. The intermediate spines are, conversely, extremely reduced. Unusually it preserves complete outlines of many of the fins.
