Libyan Desert Glass insect ground nest

This is a glass fossil about 30 M years old. This is a second ground nest for some kind of insect, perhaps an ant or termite. The longest dimension is 1.5". It was created by photogrammetry. The outside was captured in two poses and a model was rendered, and the cavities were individually made as silicone casts that were then modeled by photogrammetry and all stitched together.

This is more evidence that Libyan Desert Glass was not created by a meteor impact or airburst. I propose it was created by a radiation event such as beta radiation, which can liquefy silica without raising it to melting temperature.

The images here are the specimen itself, and an image of the virtual object cutaway to show the internal tunnels and portions of chambers. The .stl model is not cutaway and is manifold.
