Talk:Iron metallurgy in Africa

Broken citations rendering as visible "Cite error" text in the lead

The lead section contains four visible citation error messages that appear in the rendered article. In the reference list under the lead, readers see:

• "Cite error: The named reference Alpern 2005 was invoked but never defined (see the help page)."
• "Cite error: The named reference Killick_2004 was invoked but never defined (see the help page)."
• "Cite error: The named reference Holl-2020 was invoked but never defined (see the help page)."
• "Cite error: The named reference Bandama was invoked but never defined (see the help page)."

These correspond to inline citations in the lead (e.g. the sentences "Whether iron metallurgy in Sub-Saharan Africa originated as an independent innovation..." and "others contend that they undermine the diffusionist model..."). The named references are actually defined later in the body — for instance Alpern (2005), Killick (2004), Holl (2020), and Bandama & Babalola (2023) all appear as full citations in the "Origins and spread in Africa" section. The name="..." attributes in the lead simply do not match the name="..." attributes on the full definitions further down. Either the definitions should be moved to (or duplicated at) the first invocation in the lead, or the names should be harmonised so the references resolve.

Lead contradicts itself and the body on when iron metallurgy began in West/Central Africa

The lead gives two incompatible start-dates for iron metallurgy in West and Central Africa within adjacent paragraphs, and both conflict with the body.

Paragraph 1 of the lead states: "Following the beginning of iron metallurgy in Western and Central Africa by 800 BC - 400 BC, and possibly earlier..."

Paragraph 2 of the lead states: "In the first decades of the twenty-first century, radiocarbon and thermoluminescence dating of artifacts associated with iron metallurgy in Nigeria and the Central African Republic have yielded dates as early as the third millennium BC."

The body ("Origins and spread in Africa") goes further still, reporting: "some surprisingly early radiocarbon dates had been obtained for iron smelting sites in both Niger and central Africa (Rwanda, Burundi)... as far back as 3600 BCE", and: "Iron metallurgical development occurred 2631 BCE – 2458 BCE at Lejja, in Nigeria, 2136 BCE – 1921 BCE at Obui, in Central Africa Republic, 1895 BCE – 1370 BCE at Tchire Ouma 147, in Niger, and 1297 BCE – 1051 BCE at Dekpassanware, in Togo."

The "800 BC – 400 BC" figure in the first lead paragraph is therefore inconsistent both with the second lead paragraph and with the body's own reported dates. The lead should be rewritten so the earliest-dates claim is stated once, with the disputed/contested status of the third-millennium dates flagged, rather than presenting two mutually exclusive ranges as fact.

Two inconsistent dates given for iron smelting at Lejja, Nigeria

The "Origins and spread in Africa" section gives two different dates for iron smelting at Lejja within a few paragraphs of each other.

First: "In the Nsukka region of southeast Nigeria (now Igboland), archaeological sites containing iron smelting furnaces and slag have been excavated dating to 750 BCE in Opi (Augustin Holl 2009) and 2,000 BCE in Lejja (Pamela Eze-Uzomaka 2009)."

Then, a paragraph later: "Iron metallurgical development occurred 2631 BCE – 2458 BCE at Lejja, in Nigeria..."

A ~500–600-year discrepancy for the same site is not explained. Either the two statements refer to different phases/samples at Lejja and this should be spelled out, or the article is quoting two incompatible interpretations of the same evidence as if both were established fact. Also worth reconciling: the same paragraph gives "2136 BCE – 1921 BCE at Obui", while the earlier discussion of the same site (spelled "Oboui") reports "eight consistent radiocarbon dates of 2000 BCE" — the spelling should be unified and the two date ranges reconciled or attributed to different analyses.
