Archaeologists in Egypt have discovered a large ram-headed sphinx that is linked to King Tutankhamun’s grandfather, Fox News reported.

The sphinx, which is 16.4-feet long, 11.5-feet high and 5-feet wide, was found beneath several feet of debris at Gebel-el-Silsila, an ancient quarry on the Nile. Only its head was visible prior to excavation.

The sculpture is believed to be from the time of King Tut’s grandfather, the pharaoh Amenhotep III, who ruled in the 14th century B.C.

The criosphinx (or ram-headed sphinx) is carved in a similar style to those at the famous Khonshu Temple at the huge Karnak complex, according to experts.
