The earliest vertebrates had the cranial structures or head but they lacked the vertebral columns and the jaws. These earliest vertebrates lived around 500 to 600 million years ago.
The earliest vertebrates which lacked the vertebral columns and are still alive are the Hagfish and the sea lampreys. These are considered the earliest vertebrates as they lacked the jaws.
