A second ancient monolith was discovered in the same quarry alongside the Stone of the South only in the 1990s. With its weight estimated at 1,242 t, it even surpasses the dimension of the well-known Stone of the Pregnant Woman.
The established dimensions of the rectangular limestone block, on the assumption that it continues its shape in the hidden parts underground, are:
* 19.5–20.5 m length
* 4.34–4.56 m width
* 4.5 m height
* 2.6–2.8 g/cm³ density
