This is another Sassanid silver plate probably from the 7th Century AD showing Senmerv, the Goddess of Fertility. Senmerv while being known as 'The Bird Dog Goddess' perched on 'The Tree of All Seeds' is seen here without any dog-like aspects to her. Senmerv was believed to scatter the seeds from the 'Tree of All Seeds' over the land. In this effort, her domain is over the Earth and involves not only the fertility of plants/soil, but also over all things that are animal in nature (flocks/herds). The Bulgar and Sarmatian way of life was dependent on Senmerv. In other ancient Turkish cultures such as the early Khazar one, goddesses such as Umay would have held sway over fertility. The word Umay has its origins to an ancient Turkish word for 'placenta'.
