3,800 yo bark handle preserved on one side. This Late Neolithic to Early Bronze Age weapon was preserved thanks to the unique conditions of the site—waterlogged, acidic, and low in oxygen—which slow down decay and create an anaerobic environment.

In 2014, a shocking discovery emerged from south Lolland, Denmark, related to the Femern-project (where they are currently building a tunnel between Denmark and Germany): a 3,800-year-old flint dagger, dating back to around 1800–1600 BC, with its bark handle preserved on one side. This Late Neolithic to Early Bronze Age weapon was preserved thanks to the unique conditions of the site—waterlogged, acidic, and low in oxygen—which slow down decay and create an anaerobic environment.

Such a find is incredibly rare, as organic materials like bark usually do not survive. The dagger highlights both the skill of ancient craftsmen and the extraordinary preservation conditions, offering rare insights into Neolithic and Bronze Age weaponry and craftsmanship. This find was made by the Museum Lolland-Falster.

Another amazing example of wood lasting thousands of years when humans put it in the right conditions.

Wisconsin archaeologists recently discovered 11 ancient canoes in Lake Mendota, outside of Madison. The canoes were found in a cache that may have been an ancient shoreline.

A bit more information on the oldest known wood pathway "the Sweet Track." Over 5,000 years old

Another example of wood preserved indefinitely in impervious soils. Here we see a 4,573-year-old neolithic wooden peat road near Nieuw-Dordrecht, in the Netherlands, excavated in the 1980s. This corduroy road was at least 800 metres long, and its construction has been dated to the year 2,549 BC thanks to dendrochronology or tree-ring dating.

Another recent discovery, this time very close to home, of clayey, anoxic conditions preserving wood for very long periods (700 years in this case).

This dugout canoe was found on the banks of the Red River! It dates to the 14th Century! At 34 feet in length, it is the largest Native American canoe ever discovered in Louisiana!

Larto Lake is connected to the Red River through Big Larto Bayou, which is where the dam is located. One can just imagine Native Americans paddling on Larto Lake and the surrounding streams in such a dugout canoe! These water bodies served as liquid highways!

There certainly were plenty of cypress trees around to use as building material. The cypress wood was impervious to insects and rot, as evidenced by this canoe which is over 700 years old! By Trevor Fry

Coal miners find a buried Roman wood ship - how ironic! These soils are not ideal for sequestration, because of relatively high permeability, but in this case the durability for wood products was still 1,700+ years. https://archaeologymag.com/2023/08/coal-miners-discover-ancient-roman-ship-in-serbia/?fbclid=IwAR2Su_8obDnvT7qXNca3cz1oVjxJi3lEbj5KHtkIDo5ODuYLAuUOoLBJ4mQ

One of the greatest carbon sequestration periods in prehistory where nature caught up to extreme natural emissions (with an atmosphere of 3000 ppm CO2 concentrations v. 420 ppm today) and brought atmospheric CO2 down to 500 ppm in 25,000 years:

The Paleocene-Eocene Thermal Maximum (PETM) was a period of natural global warming that took place almost 56 million years ago.  It came at a time when the atmospheric concentration of CO2 was already higher than today, and global temperatures also much warmer. The PETM warming was a roughly 200,0...

Preserving ‘carbon crops’ with salt and storing them in dry landfill sites to stop them decomposing could be a low-cost, scalable climate solution, according to physicist Eli Yablonovitch

Ever wondered about the benefits and the challenges of biomass-based carbon removal? Then join CSI's Christopher Knop on June 27th at 10am PT for a panel discussion with cCarbon. It's sure to be informative! Register at the link below.

Apparently sustainable, scalable, and with plenty of co-benefits: biomass-based carbon removals are gaining traction for their relative ease of generation and permanence claims. However, there is still a long way to go before these technologies can play a tangible role in achieving global and nation...
