description Melonechinus Overview

Melonechinus is an extinct genus of echinoids, the group that includes sea urchins, known from Carboniferous fossil deposits. 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.
