Stone Age Mother Cradling her Child in a ancient grave : Around 4,800 years ago, a young mother died near the Taiwanese coast. When she was lifted from her grave as part of a scientific excavation, archaeologists discovered that she had been buried with a six-month-old infant tucked into her arms. Interred near a stone dwelling, it appeared the pair had been sent into the hereafter in a loving embrace. According to the researchers, the mother was just 160 cm tall, or 5 foot 2 inches.
The infant in her arms is 50 cm tall – just over a foot-and-a-half. The find was among 48 sets of remains unearthed from graves in Taiwan, including the fossils of five children.Carbon dating was used to determine the ages of the remains which included those of five children.
