 In Ngayarda languages, including that of the indigenous people of the peninsula, the Jaburara people, "murujuga" meant "hip bone sticking out".The peninsula is a unique ecological and archaeological area since it contains the Murujuga cultural landscape, the world's largest and most important collection of petroglyphs – ancient Aboriginal rock carvings some claim to date back as far as the last ice age about 10,000 years ago.The collection of standing stones here is the largest in Australia with rock art petroglyphs numbering over one million, many depicting images of the now extinct thylacine (Tasmanian tiger).
