description Overview

Hemiaster bufo

Hemiaster bufo is an extinct species of irregular sea urchin known from Cretaceous rocks. It belongs to the family Hemiasteridae and the order Spatangoida, a group of heart urchins associated with life on or within soft marine sediment.

Its fossil remains represent the rigid test, or shell-like skeleton, of an ancient sea urchin rather than a living marine animal. The genus is studied in palaeontology as part of the early history and morphological diversity of echinoids during the Paleozoic Era.
