The tomb is full of textiles, ceramics, woodcarvings, children+s bones and red and yellow ceramics adorned with fish and wild boar motifs.

"It+s like their Fort Knox, their depositary of wealth with textiles and ... trade items and that+s what+s overwhelming about it," said head of the archeology team Stephen Houston.

The tomb dates back to 300 to 600 CE and is 10 feet by nearly four feet wide and five feet deep, Reuters reported.

The find also revealed that the king was buried in a traditional dancer+s costume, and children as young as 12 months old were sacrificed during the burial.

This is while previous studies had shown that adolescents were frequently sacrificed.

The El Zotz is only one of the many Guatemalan archeological sites housing Mayan pyramids and architectural remains. The ancient civilization flourished between 250 and 900 CE and expanded from the modern day Honduras to central Mexico.
