Keretsa

Keretsa is a genus of fossil bilaterian animal known from the single species Keretsa brutoni, found in the Late Precambrian-aged Zimnie Gory Formation near Arkhangelsk Oblast, Russia, along the Winter coast of the White Sea. The first specimens were found in 2005. Its rounded, oblong body resembles the fossil animal Naraoia, with a headshield positioned at the front and a trunk shield behind it. A pair of antennae-like structures extends from beneath the headshield, and numerous oblique grooves run along the trunk shield, suggesting the position of leg-like structures.
