A remarkable discovery near New York City has unveiled the world’s oldest forest, dating back 385 million years.
Located in Cairo, Green County, about two hours north of the city by car, the ancient forest offers a glimpse into a prehistoric world that even predates the dinosaurs.
Early plant life in the world’s oldest forest
Researchers from SUNY Binghamton and Cardiff University in Wales have unearthed fossils of early plant life at the site.
The forest, stretching from New York to Pennsylvania, featured trees as tall as 65 feet with trunks up to five feet in diameter.
This discovery is pivotal in understanding the planet’s climatic evolution, as the emergence of trees played a crucial role in altering Earth’s climate by absorbing carbon dioxide and laying the groundwork for the atmosphere that supports human life.
First uncovered in 2009, the archaeological site has been meticulously analyzed by the team to accurately date the trees and identify the species that once thrived there.
Christopher Berry, a paleobotanist from Cardiff University, described the experience: “You are walking through the roots of ancient trees. Standing on the quarry surface we can reconstruct the living forest around us in our imagination.”
Fossilized woody roots
The site, roughly half the size of a football field, contains rocks aged at 385 million years. The discovery of fossilized “woody roots” of old trees marks a significant turning point in Earth’s history.
These roots, with their unique horizontal radial patterns, indicate where vertical tree trunks once stood.
Predominantly, the forest’s trunks were from Archaeopteris, a tree species with large wooden roots and leafy branches.
The forest also housed cladoxylopsids, an extinct group of sphenopsids and ferns, and a third yet-to-be-identified tree type.
Interestingly, all these trees reproduced through spores rather than seeds, a process where small cells multiply to create more plants.
Geochemical changes
Kevin Boyce, a geoscientist at Stanford Universityhighlighted the significant impact these trees had on the ancient climate.
Their growth process involved “weathering,” a chemical reaction that extracts carbon dioxide from the atmosphere and converts it to carbon ions in groundwater, which eventually flows to the sea and gets absorbed in limestone.
The researchers believe that a massive flood led to the forest’s demise, a theory supported by the discovery of multiple fish fossils on the quarry’s surface.
Berry noted the unexpected coexistence of plants previously thought to inhabit mutually exclusive environments.
He explained how they drilled into the fossil soil between the trees to investigate geochemical changes.
Preserving the world’s oldest forest
In 2020, New York State Assemblyman Chris Tauge introduced a resolution to the Cairo Town Board to protect this significant area.
John Coyne, the supervisor of Cairo, expressed pride and excitement about this discovery, underscoring the collaboration between the county, state, and the town for its preservation.
Before this discovery, the oldest known forest was in Gilboa, New York, located about 25 miles from the Cairo site.
Discovered in the late 19th century, the Gilboa forest was home to Gilboa Trees, or Eospermatopteris, one of the earliest plant species on Earth.
These fern-like trees, reaching around 30 feet tall, lacked wood. A preserved tree stump from Gilboa, initially displayed in a museum in the mid-1900s, was later moved to the Cultural Education Center in Albany, New York.
This fascinating find not only pushes back the timeline of our planet’s botanical history but also opens new doors for understanding how ancient ecosystems functioned and evolved.
The Cairo forest, with its deep historical roots and significant scientific value, stands as a testament to the enduring wonders of the natural world.
