Just because the article is wrong does not mean that it cannot serve as starting point for interesting discussions.
Not "a similar object", that would imply an independent item which happens to share visible features. The video is a modern 3D printed replica of these..
Not even speaking of the general tone and wild ramblings scattered throughout the article.
Edit: The number series are not even correct. For the first series (.875, 1.75, 2.265, 3.5, 4.375, ...) the third number should be 2.625 and not 2.265. It is even bolded.
Speculated uses include as a candlestick holder (wax was found inside two examples); dice; survey instruments for estimating distances to (or sizes of) distant objects;[4] devices for determining the optimal sowing date for winter grain;[5] gauges to calibrate water pipes, army standard bases, a coin measuring device for counterfeit detection. Use as a measuring instrument of any kind seems improbable since the dodecahedra were not standardized and come in many sizes and arrangements of their openings.
The evidence for this consists mostly of some rocks piled up to make some fences - technology the Maori couldn't hope to replicate until the white man came along and showed them how.
This apparently means, amongst other things, that the Treaty of Waitangi (founding document for NZ) is null and void as the Maori are not the original/actual Tangata whenua.
