Etymology

edit

The name Magallanodon comes from the Magallanes Region in southern Chile and odontos, Greek for tooth. The species name, M. baikashkenke is taken from the Tehuelchian words bai (grandfather) and kashkenke (valley) - Grandfather's Valley is the name for the region where the fossil was first found, also called the Río de Las Chinas.[1]
