Pacal, the alleged ruler of Palenque
had an extraordinary deformation of the head as well as an
extraordinary long bridge that went up to the brow.
A fairly unique appearance.

Die The ruler's death mask was made out of jade.

Jade is not available in Central America, but should have come from China.

Pacal displayed on the brass.
Based on the interpretation of archeologists, he fell in the mouth
of the earth monster. The monster's beard hairs can be seen below.

It most probably looks like that he is sitting in a vehicle
with a unique fire beam emission at the lower end of the image.

Modern science confirms that the Maya did not know about the wheel.
Here is some "toys", found in Mayaruins.
So much for the ignorance of archeologists.
