Early Agriculture in the Maya Lowlands
Wetland research in northern Belize provides the earliest evidence for development of agriculture in the Maya Lowlands. Pollen data confirm the introduction of maize and manioc before 3000 B.C.…

Bedout: A Possible End-Permian Impact Crater Offshore of Northwestern Australia
The Bedout High, located on the northwestern continental margin of Australia, has emerged as a prime candidate for an end-Permian impact structure and the identification of melt rocks and impact breccias from drill cores located on top of Bedout are consistent with the presence of a buried impact crater.
Origin and environmental setting of ancient agriculture in the lowlands of Mesoamerica.
Archaeological research in the Gulf Coast of Tabasco reveals the earliest record of maize cultivation in Mexico. The first farmers settled along beach ridges and lagoons of the Grijalva River delta.…
Five Thousands Years of Land Use and Abuse in the Southern Argolid, Greece
O REECE is, in the main, a land of dry and barren mountains, poor in fertile, wellk3watered soil. Still, ancient authors refer repeatedly to the wooded hills and rich bottomlands of a remote past.…

A phytolith analysis of sediments from San Andrés, Tabasco, is reported that confirms the spread of maize cultivation to the tropical Mexican Gulf Coast >7,000 years ago (≈7,300 calendar years before present) and amplifies the present evidence for widespread maize dispersals into Central and South America.
