caption: The image shows a black and white photo of a piece of rock with a bird on it, which is believed to be a fragment of a bone fragment from the Neolithic period. The bone fragment is in the shape of a bird, with its wings spread out and its head slightly tilted to the side. Its beak is curved and its eyes are closed, giving it a peaceful expression. The bird is perched atop the rock, its feathers ruffled and its tail feathers fanned out behind it.
