The Abric Romaní site in Spain is rather unique in archeology for one simple reason: the caves in its limestone-rich cliff have seen humanoid occupation for thousands of years. A thick layer of calcium carbonate-based travertine deposit has, over time, covered and largely preserved tools and other implements, including those made of wood. Over many decades of archeological exploration, 597 wooden imprints have been uncovered, with a recent research article by [Palmira Saladié] et al. detailing these findings.

Wood is one of those archaeological artefacts that are very elusive due to their fragility, even though we know that wood has been used pretty much everywhere from the first day that a humanoid critter discovered that branches make great clubs and spears, and can also easily be shaped to make them even more useful.

The wooden imprints and some larger remains of wooden implements were found, ranging from wooden spears and clubs to trays (see heading image) and tripods. With enough of the wood still present, researchers were also able to determine which types of trees were used to make these tools, and sometimes which part of the tree.

These finds date back to between 62,000 and 40,000 years ago during the Middle Paleolithic era. This would have been around the time that Homo sapiens began to move into Europe, with both species of humans living side by side for thousands of years. These days, the only active traces of this can be found in our DNA, which retains bits of H. neanderthalensis.

The supplemental materials PDF  breaks down some of this site’s more recent history. The sole reason that this crucial archaeological site was discovered was that the landowner in the early 20th century expressed a profound interest in archaeology and other natural sciences.

Thanks to this lucky find, we gained some insight into how our ancestors would have learned how to create crude wooden implements, before eventually moving on to smelting metals and eventually sand in order to make it into computer chips.

The Stone Age owes its name to tools that survived to our time. The material early humans worked with most, though, was probably wood because it is so much easier to process. Unfortunately, we know very little about Paleolithic woodwork because wood rots relatively quickly. But at Abric Romaní, a rock shelter in Capellades, west of Barcelona, mineral-rich water coated wooden Neanderthal tools in a limestone-like crust. When wood rotted away, it left behind hollow molds that faithfully reflect its shape.

In a recent Science Advances study, a team of Spanish archaeologists has cataloged 597 wooden remains from Neanderthal living areas dating from 62,000 to 40,000 years ago. They found spears, digging sticks, bark trays, parts of shelters, and a club unlike anything seen before, suggesting Neanderthals were likely much more than just Homo sapiens’ dumber cousins.

Beyond hunting gear

The oldest wooden artifacts we have are mostly weapons. They include spears from a German town called Schöningen, a spear tip from Clacton-on-Sea in England, and the spear found alongside an elephant skeleton in Lehringen, Germany. Most came from waterlogged sediments, where a lack of oxygen slowed decay.
