Around 370,000 BCE, pre-Neanderthal hominins at Bilzingsleben, Germany created organized engravings on bone and ivory artifacts. An elephant tibia fragment displays regularly spaced parallel lines arranged in symmetric patterns. The markings demonstrate deliberate planning and precision. The site contains artifacts indicating organized living spaces and tool manufacturing. These engravings suggest early hominins possessed cognitive capabilities for pattern recognition and creation, indicating abstract thinking abilities existed before modern humans evolved.
