Design and performance of microlith implemented projectiles during the Middle and the Late Epipaleolithic of the Levant: experimental and archaeological evidence
Open accessAbstract
The study comprises an experimentally based investigation of interaction between temporal change in the morphology of microlithic tools and transformations in projectile technology during the Late Pleistocene in the Levant. Archery experiments with differently designed arrows fitted with various types of microliths representing subsequent Epipaleolithic cultures of the Levant allowed analyzing performance abilities of the arrows, identifying projectile damage types characteristic of particular hafting modes, detecting factors influencing the frequency of projectile damage and estimating the frequency of projectile damage expected to be found in archaeological samples. The data obtained through the experiments applied in the analysis of the archaeological microliths from Geometric Kebaran and Natufian sites in Israel indicate different approaches to the design of projectiles fitted with microliths characteristic for these cultures. The shift in design, associated with such important economic and social transformations as transition to sedentary settlements and a broad-spectrum economy, may reflect a demand for light, flexible and efficient projectile weapons requiring low time and labor investment for preparation and retooling. The use of such efficient weapons in conditions of growing population density and restricted areas available for Natufian hunter–gatherers can be considered as one of the factors that could have affected the subsequent transition to food production that took place in the early Holocene.

TL;DR
Archery experiments with 102 arrows and 265 microlith replicas show that Epipaleolithic projectile design affects penetration, durability, ricochet frequency, and diagnostic impact fractures. Comparing experimental damage with Geometric Kebaran trapeze/rectangles from Neve David and Natufian lunates from el-Wad Terrace suggests a shift from microliths used mainly as lateral elements to lunates hafted mainly as transversal/oblique tips.
Key findings
- Arrow performance varied by design: oblique points averaged 23.0 cm penetration, transversal points 22.6 cm, and self-pointed arrows with lateral blades 22.5 cm; straight points averaged 15.0 cm, double oblique points 11.0 cm, the microgravette-plus-four-barb arrow 11.5 cm, and self-pointed arrows with twisted barbs 5.6 cm. Ricochets were most common among double oblique points (50%), followed by transversal points (22%), straight points (11.8%), and oblique points (8%).
- Diagnostic projectile damage frequencies were highest for single straight points (53.8%) and transversal points (40%), while lateral blades showed only 12.5% diagnostic damage. Among barbs, Helwan lunates remained undamaged in 87% of cases, compared with 46% for lunates with abrupt retouch, 39% for trapeze/rectangles, 33% for Kebara points, and 25% for arch-backed bladelets.
- Taphonomic analysis estimated that more than 40% of shot microliths would be lost in hunting; projectile damage expected in archaeological assemblages was estimated at 7.9–26.5%. Archaeological samples showed diagnostic projectile damage on 5.3% of Neve David trapeze/rectangles and medial parts and 8.4% of el-Wad Terrace lunates.
- At Neve David, parallel fractures and fractures along a sharp edge dominated, suggesting trapeze/rectangles were hafted predominantly as side elements/lateral blades. At el-Wad Terrace, 23 of 25 damaged lunates had oblique/perpendicular fractures initiating on a sharp edge, suggesting transversal hafting at the tip, with two exceptions showing parallel fractures.
Methods
- Experimental archery used 102 arrows incorporating 265 microlith replicas, shot by Dmitry Nuzhnyy with a recurved wooden sport bow of 17.5 kg power. The first session targeted a freshly killed unskinned female goat on Mount Carmel in December 2006 at 13 m, then 10 m, then 8 m; the second session targeted a skinned sheep thorax encased in cardboard at 5 m.
- Macrofractures diagnostic of projectile impact were classified by initiation location and orientation relative to the microlith’s longitudinal axis; selected experimental and archaeological microliths were inspected with SEM for micro-fractures.
- Archaeological analysis used all trapeze/rectangles from two 1 m² units at Geometric Kebaran Neve David (N=311, plus 85 medial parts) and all 299 lunates from two 1 m² units at Natufian el-Wad Terrace (182 Helwan, 117 abrupt retouch); three Neve David trapeze/rectangles and seven el-Wad lunates were examined by SEM.
Limitations
- The paper states that samples of arrows with a particular design fitted with a particular microlith type were relatively small, precluding detailed statistical analyses; it also states that further experiments are needed on lunate durability, Final Natufian small lunates, desert Geometric Kebaran wide trapeze/rectangles, and lateral-blade fracture types, and that the suggested projectile-design shift requires confirmation from additional Geometric Kebaran and Early Natufian samples.
- Evident from the text: the experiments used animal carcasses/thorax rather than live hunting, and the taphonomic estimate was based on the first session and all microliths without accounting for hafting mode, which the paper notes affects damage frequency.
- Evident from the text: the archaeological comparison is limited to two sites and two 1 m² excavation units per site, so broader assemblage variability is not captured.

“The presence of prominent and deep fractures along a sharp edge and insignificant occurrence of fractures indicating hafting as straight points in conjunction with the low frequency of projectile damage suggest that the trapeze/rectangles were hafted predominantly as side elements, most probably as lateral blades attached parallel or in a slight angle to the shaft (Fig. 14: 1-3).”

“We suggest that the shift in the type of the dominant microlith from trapeze/rectangle to lunate was associated with a different approach to the design of projectiles, namely, a decrease in the use of microliths as lateral components of the projectiles and their predominant hafting as tips, including transversal points.”

A conclusion the paper draws from its own results — it cites no other source for it, so there is none to check. The quote shows it is in the paper.
In the paper
“The differences in the durability indices can be explained by differences in the location of the microlith on the shaft and by the extent of protrusion of the microlith from the adhesive.”

None of the sources cited for this claim could be matched to a paper in Crossref, so there is nothing to check it against.
In the paper
“A single parallel fracture initiating on a retouched edge and crossing the microlith body is also characteristic mostly of straight points (see also Nuzhnyy, 1990Nuzhnyy, , 1993)), although this type of damage may occasionally occur on long non-geometric microliths hafted as barbs as a result of removing the arrow from the target.”

The experimental fracture patterns produced by shooting microliths into a goat carcass are analogous to those produced in prehistoric hunting.
“Based on the frequency of damage diagnostic of projectile impact among the microliths recovered from the target and from the arrows, and taking into consideration that in a real hunting situation damaged microliths embedded in the arrows could have been replaced, we suggest that projectile damage expected to be found in archaeological assemblages range between 7.9-26.5%.”

The experimental sample of microliths and shooting sessions is representative of past projectile use and hafting variability.
“The experiments have demonstrated that most types of single fractures diagnostic of projectile impact can occur on differently hafted microliths and cannot provide a reliable base for reconstructing mode of hafting.”
The paper relies on this without support.
The archaeological microliths with diagnostic fractures were used as projectiles and their fractures were caused by projectile impact.
“Damage diagnostic of projectile impact occurred on 5.3% of the microliths from the Geometric Kebaran site of Neve David and on 8.4% of the lunates from el-Wad Terrace.”

The taphonomic processes affecting microliths in the experiments are similar to those in prehistoric hunting and discard.
“Our taphonomic analysis of microlithic implements has shown that more then 40% of shot microliths are expected to be lost in hunting activity.”

The experimental arrows with microliths accurately represent the actual projectiles used in the Epipaleolithic.
“Our study was based on experiments intended to represent a wide range of projectile designs and types of microliths.”
Self-check
Percentages, sums and reported differences re-computed from the paper’s own numbers.
Each contradiction between two passages listed here was confirmed by an independent check.
el-Wad diagnostic lunates are assigned to different types in Tables 7 and 8
MinorTable 7 reports diagnostic damage on 15 Helwan and 10 abrupt-retouch lunates; Table 8 instead labels 14 Helwan and 11 abrupt lunates. Both give 25 overall, but the type-specific counts disagree.
“| el-Wad Terrace | Helwan lunate Lunate abr. etouch Lunate varia | 135 93 18 | 84.4 79.5 81.8 | 15 10 - | 9.4 8.5 - | 10 14 4 | 6.3 12.0 18.2 | 160 117 22 | 100.0 100.0 100.0 |”
“| el-Wad Terrace | Helwan lunate N=14 Abrupt lunate N=11 Total el-Wad Terrace |”
Second-session total is labelled with the whole-study count
MinorA row labelled "Total second session" gives 265 microliths, while the paper states that 265 is the total number prepared for the study and separately lists 102 for the first session.
“Total second session 65 24.5 69 26 102 38.5 29 10.9 265 100”
“For the present study 102 arrows were made incorporating a total of 265 microlith replicas prepared by Dodi Ben Ami.”
Straight-point penetration index does not match the table counts
MinorIndex 2 is defined as target penetrations divided by arrows. Table 1 gives 15 penetrations for 12 straight-point arrows, yielding 1.25, not the reported 1.4.
Reported 1.4 · recomputed 1.25
“| Straight points N=12 | 15 | 2 | 14 | 31 | 15.0 | 2.6 | 1.4 | 11.8 |”
Neve David diagnostic-fracture counts differ between tables
MinorTable 7 reports five diagnostic medial parts and 21 diagnostic microliths in total, whereas Table 8 labels six medial parts and 22 in total.
“| Neve David | Trapeze/rectangle Medial parts Total | 254 80 334 | 81.7 94.1 84.3 | 16 5 21 | 5.1 5.9 5.3 | 41 -41 | 13.2 -10.4 | 311 85 396 | 100.0 100.0 100.0 |”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-11-08, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-11-08 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
