Namapoikia rietoogensis is among the earliest known animals to produce a calcareous (probably aragonite) skeleton.[1] Known from the Ediacaran period, before the Cambrian explosion of calcifying animals, the organism grew up to a metre in diameter and resembles a colonial sponge or cnidarian.[2] It was an encruster, filling vertical fissures in the reefs in which it originally grew.[3]
The fossil was first found in the Omkyk Member from Rietoog in southern Namibia, in association with another calcifying fossil, Cloudina.
