While conducting research on Maya archaeology, a student took the following notes:
- In 2018, archaeologist Dr. Takeshi Inomata discovered Aguada Fénix, a Maya site in Tabasco, Mexico.
- Aguada Fénix dates from 1000 BCE to 800 BCE, making it the oldest monumental structure in the Maya region.
- The main platform of the site is also the largest Maya structure, measuring 1,400 meters in length.
- The platform was constructed of clay and earth, rather than the stone typical of later Maya architecture.
The student wants to complete a sentence that emphasizes the age of the Aguada Fénix platform, its massive length, and its specific building materials. How should the blanks in the sentence be completed to achieve this goal using the specific details from the notes?
