Abstract

A polished meteorite slice with known dimensions reveals multiple internally coherent features highlighted by yellow arrows. Direct measurement using an in-figure scale bar demonstrates that these features are millimeter-scale (approximately 1–2 mm wide). This size range excludes biological cells and is inconsistent with established meteoritic textures, including Widmanstätten patterns, shock veins, melt pockets, mineral nodules, and fracture fills. The features’ sharp boundaries, uniform widths, finite terminations, and repeated modular occurrence collectively rule out geological origin. We argue that the most parsimonious interpretation is that these structures represent artifacts—man-made inclusions preserved within the meteorite material.

1. Material and observational context

The specimen is a flat, polished meteorite slice whose surface allows direct morphological inspection. The yellow-arrowed features appear as discrete, elongated elements embedded within the meteoritic matrix. They are visually distinct from surrounding textures and recur with comparable size and geometry across the slice.

2. Measurement method

The figure includes a 5 mm scale bar, providing a direct and reliable reference. Each yellow-arrowed feature is visibly shorter than the scale bar, typically measuring approximately one-third to one-half of its length. This yields a conservative width estimate of ~1–2 mm. Because the scale bar lies in the same plane as the features, no camera metadata or optical assumptions are required.

3. Exclusion of biological origin

Natural biological cells, including plant vessel elements and fibers, are orders of magnitude smaller:

• Typical wood cells: 10–100 µm

• Largest known vessel elements:

No biological structure forms discrete, bounded elements at 1–2 mm width while maintaining consistent geometry. A biological explanation is therefore excluded on scale alone.

4. Systematic exclusion of geological origin4.1 Widmanstätten patterns

Widmanstätten patterns consist of crystallographically controlled kamacite–taenite lamellae that are planar, slab-spanning, and characterized by predictable orientations and diffusion-controlled thickness variation. The observed features are instead discrete, bounded modules with finite terminations and uniform width, lacking crystallographic continuity.

4.2 Shock and melt features

Shock veins and melt pockets display irregular geometry, branching, variable aperture, and diffuse boundaries. None of these characteristics are present in the yellow-arrowed structures, which maintain sharp margins and consistent dimensions.

4.3 Mineral nodules and segregation textures

Troilite nodules and other segregations are equant or irregular and do not occur as repeated, elongated modules of uniform width. The observed features do not match these morphologies.

4.4 Fractures

Natural fractures vary in aperture, cross-cut surrounding textures, and commonly branch or terminate irregularly. The yellow-arrowed features do not exhibit these behaviors.

Taken together, no known meteoritic or geological process accounts for the observed morphology.

5. Indicators of artificial origin

After excluding biological and geological mechanisms, the remaining explanation must account for:

1. Millimeter-scale size exceeding biological limits

2. Uniform width across multiple features

3. Sharp, persistent boundaries

4. Finite terminations rather than slab-spanning continuity

5. Repetition of similar modules within the same specimen

These characteristics are consistent with artifacts, defined here as structures produced by intentional fabrication rather than natural self-organization.

6. Interpretation

The yellow-arrowed features are best interpreted as man-made artifacts incorporated into the meteoritic material prior to its final consolidation. Their preservation through meteoritic history suggests incorporation at an early stage, followed by survival during subsequent thermal and mechanical processes.

---

7. Conclusion

Direct measurement using an in-figure scale bar shows that the yellow-arrowed structures are approximately 1–2 mm wide. This size excludes biological cells and, together with their bounded, repetitive morphology, systematically rules out geological origin. The evidence supports the interpretation that these features represent artifacts embedded within the meteorite.
