Evolutionary history of plants seed model is shared by basically all gymnosperms (literally: "naked seeds"), most of which encase their seeds in a woody cone or fleshy aril (the yew, for example), but none of which fully enclose their seeds. The angiosperms ("vessel seeds") are the only group to fully enclose the seed, in a carpel. Fully enclosed seeds opened up a new pathway for plants to follow: that of seed dormancy. The embryo, completely isolated from the external atmosphere and hence protected from desiccation, could survive some years of drought before germinating. Gymnosperm seeds from the Late Carboniferous have been found to contain
Stele of the Vultures vultures after which the stele is named, with the severed heads of the enemies of Lagash in their beaks. The second register shows soldiers marching with shouldered spears behind the king, who is riding a chariot and holding a spear. In the third register, a small part of a possibly seated figure can be seen. In front of him, a cow is tethered to a pole while a naked priest standing on a pile of dead animal bodies performs a libation ritual on two plants spouting from vases. Left of these scenes is a pile of naked bodies surrounded by
