# FOSSIL — sources and interpretation

FOSSIL — Deep Time in Stone is an authored ten-movement exhibition. The FSL—001 study identifier belongs to the artwork. No museum accession, collecting locality, geological age, scan resolution or calibrated physical units are assigned.

The hero, specimen, strata, preparation, preservation, amber and archive image plates are AI generated. They are illustrations, not documentary photographs. Their separate [source notice](licenses/AI-Assets-Notice.md) is retained; the code license does not grant or assert exclusive rights in generated raster images.

The 192 × 192 × 72 density field, all 72 virtual sections and intentionally incomplete Marching Cubes model are seeded authored data. The reconstruction is not derived from image pixels, a downloaded fossil dataset or real CT acquisition. The hardware and CPU paths render the same isosurface. Original synthetic outputs and source are covered by the supplied [scoped MIT license](LICENSE.txt).
