Nineteenth century tools made from sharks’ teeth suggest that two species of shark used to populate the Central Pacific but are no longer present.

Using artifacts from museums, a team of US researchers found that spot-tail and dusky sharks used to inhabit the reefs surrounding the Gilbert Islands.

The unusual historical data would help evaluate the success of ecological conservation measures, they added.

In their paper, the team from the Field Museum of Natural History, Chicago, and Columbia University, New York, said indigenous artifacts often represented an “under-utilized source of data.”

十九世紀用鯊魚牙齒製作的工具,顯示兩種鯊魚原本生活在中太平洋,現在卻已不復存在。

利用博物館裡的工藝品,一支美國研究團隊發現,尾點鯊與灰真鯊原本居住在吉爾伯特島周邊的礁群中。

他們還說,這種稀奇的歷史資料,有助評估生態保育措施的成效。

在他們的報告中,這個來自芝加哥菲爾德自然史博物館與紐約哥倫比亞大學的團隊說,原生工藝品往往代表「未充分利用的資料來源」。
