Ugallu
Ugallu, the "Big Weather-Beast", (Sumerian inscribed 𒌓𒃲𒆷/UD.GAL.LA, Akkadian: ūmu rabû, meaning "big day"; or, better in this case: "big storm"). It was a lion-headed storm-demon and has the feet of a bird who is featured on protective amulets and apotropaic yellow clay or tamarisk figurines of the first millennium BC but had its origins in the early second millennium.
