Keretsa brutoni is a fossil bilaterian from 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. [2] This rounded oblong-shaped organism resembles Naraoia, in having its body divided into an anteriorly positioned headshield, and a trunkshield. A pair of antennae-like structures emanate from underneath the base of the headshield, and there are numerous oblique grooves along the trunkshield that suggest legs. [2]
The trunk axial part of Keretsa specimen is wrinkled, and we can not prove either an opposite or an alternate (as in the Proarticulata) arrangement of the half-segments.
