Ha! It's Venus of Willendorf, ca. ~25000 BCE although the earliest example date to ~35000 BCE. Commonly considered a fertility totem, although there's a question in my mind as to how someone became so corpulent in a non-agrarian society at the end of the last "ice age." More curious is the strange depiction of the head.
The more interesting theory is that these were the first "ladies of the lake," that is, they were the original drowned goddesses. The ankles are in a position suggesting they were bound, the elbows likewise if they were bound behind the back, the wrists bound upon the breast. The curious shape of the head perhaps a woven basket placed over the head of the woman sacrificed to the waters, her corpulence a result of bloat after being weighted down & left to marinate.
