“…Algorithms for reconstructing 3D models from CT images were tested on a 40,000-year-old Palaeolithic wooden hunting weapon found in the Ljubljanica River (Slovenia) in 2008 [ 2 ]. To obtain an assessment of the quality of the represented 3D volume and surface model, the algorithms were tested on four other archaeological objects (bone flute from Divje babe I [ 69 ] and three ceramic rattles from the Bronze Age [ 93 ]).…”

“…With the new approach in computer vision, mainly using algorithms for 3D surface-based modelling in the processing of 2D image records, we wanted to highlight the suitability and applicability as well as the analytical and documentary importance of 3D volumetric models in computer vision and heritage science. At the same time, we wanted to answer some open questions about the observed changes in 3D surface-based models of Palaeolithic wooden point from its discovery to the completion of conservation [ 2 , 4 , 5 , 7 ].…”

“… The 40,000 years old Palaeolithic wooden point, only one out of eight wooden artefacts of such age known in Europe, was found in 2008, submerged in the river Ljubljanica at Sinja Gorica [ 2 ]. As any waterlogged wooden artefact it had to undergo a conservation process to prevent it’s complete deterioration once taken out of water [ 4 ].…”

“…Our interest in reconstructing 3D solid models using computed tomography was piqued when we were confronted with the deformation changes of a Palaeolithic wooden point [ 1 ] ( Figure 1 ). The 40,000-year-old wooden point was found underwater in the Ljubljanica River close to Sinja Gorica ( Figure 2 ) in 2008 [ 2 ]. The Ljubljanica River flows in that part on the Ljubljana Moor, which is dotted with numerous prehistoric pile dwellings, some of which are also on the UNESCO World Heritage List.…”

A rare and valuable Palaeolithic wooden point, presumably belonging to a hunting weapon, was found in the Ljubljanica River in Slovenia in 2008. In order to prevent complete decay, the waterlogged wooden artefact had to undergo conservation treatment, which usually involves some expected deformations of structure and shape. To investigate these changes, a series of surface-based 3D models of the artefact were created before, during and after the conservation process. Unfortunately, the surface-based 3D models were not sufficient to understand the internal processes inside the wooden artefact (cracks, cavities, fractures). Since some of the surface-based 3D models were taken with a microtomographic scanner, we decided to create a volumetric 3D model from the available 2D tomographic images. In order to have complete control and greater flexibility in creating the volumetric 3D model than is the case with commercial software, we decided to implement our own algorithm. In fact, two algorithms were implemented for the construction of surface-based 3D models and for the construction of volumetric 3D models, using (1) unsegmented 2D images CT and (2) segmented 2D images CT. The results were positive in comparison with commercial software and new information was obtained about the actual state and causes of the deformation of the artefact. Such models could be a valuable aid in the selection of appropriate conservation and restoration methods and techniques in cultural heritage research.

“…Other prominent finds are the tip of a spear found about 100 y ago at Clacton-on-Sea (4) and a spear found out of stratigraphic context at Lehringen (5). Other wooden items, which have been identified as possible weapons, have been recovered from Cannstatt I, Stuttgart, Germany (18); Bilzingsleben, Germany (19); Ljubljansko Barje, Slovenia (20); and Florisbad, South Africa (21).…”

Excavations for the construction of thermal pools at Poggetti Vecchi (Grosseto, Tuscany, central Italy) exposed a series of wooden tools in an open-air stratified site referable to late Middle Pleistocene. The wooden artifacts were uncovered, together with stone tools and fossil bones, largely belonging to the straight-tusked elephant The site is radiometrically dated to around 171,000 y B.P., and hence correlated with the early marine isotope stage 6 [Benvenuti M, et al. (2017) 88:327-344]. The sticks, all fragmentary, are made from boxwood () and were over 1 m long, rounded at one end and pointed at the other. They have been partially charred, possibly to lessen the labor of scraping boxwood, using a technique so far not documented at the time. The wooden artifacts have the size and features of multipurpose tools known as "digging sticks," which are quite commonly used by foragers. This discovery from Poggetti Vecchi provides evidence of the processing and use of wood by early Neanderthals, showing their ability to use fire in tool making from very tough wood.
