have developed terracotta sculptures, through large-scale economic production, as part of a complex funerary culture that may have included practices such as feasting. The earliest Nok terracotta sculptures may have developed in 900 BCE. Some Nok terracotta sculptures portray figures wielding slingshots, as well as bows and arrows, which may be indicative of Nok people engaging in the hunting, or trapping, of undomesticated animals. A Nok sculpture portrays two individuals, along with their goods, in a dugout canoe. Both of the anthropomorphic figures in the watercraft are paddling. The Nok terracotta depiction of a dugout canoe may indicate that Nok people used dugout canoes to transport cargo, along tributaries (e.g., Gurara River) of the Niger River, and exchanged them in a regional trade network. The Nok terracotta depiction of a figure with a seashell on its head may indicate that the span of these riverine trade routes may have extended to the Atlantic coast. In the maritime history of Africa, there is the earlier Dufuna canoe, which was constructed approximately 8000 years ago in the northern region of Nigeria; as the second earliest form of water vessel known in Sub-Saharan Africa, the Nok terracotta depiction of a dugout canoe was created in the central region of Nigeria during the first millennium BCE. Latter artistic traditions of West Africa – Bura of Niger (3rd century CE – 10th century CE), Koma of Ghana (7th century CE – 15th century CE), Igbo-Ukwu of Nigeria (9th century CE – 10th century CE), Jenne-Jeno of Mali (11th century CE – 12th century CE), and Ile Ife of Nigeria (11th century CE – 15th century CE) – may have been shaped by the earlier West African clay terracotta tradition of the Nok culture. Mountaintops are where the majority of Nok settlement sites are found. At the settlement site of Kochio, the edge of a cellar of a settlement wall was chiseled from a granite foundation. Additionally, a megalithic stone fence was constructed around the enclosed settlement site of Kochio. Also, a circular stone foundation of a hut was discovered in Puntun Dutse. Iron metallurgy may have developed in the Nok culture between 750 BCE and 550 BCE, though it may have developed earlier than 1000 BCE. Based on stylistic similarities with the Nok terracottas, the bronze figurines of the Yoruba kingdom of Ife and the Bini kingdom of Benin may have been continuations of the
