+description = """Food web of the early Eocene Messel Shale (Germany), a fossil site about 48 million years old that preserves the lake and surrounding forest ecosystem of the time, compiled by J. A. Dunne, C. C. Labandeira and R. J. Williams. Nodes are taxa (plants, animals, fungi, bacteria) and non-living resources (detritus and dead animal material), and a directed edge points from a consumer to the resource it feeds on. Feeding links were inferred from several lines of evidence, such as gut contents, coprolites, damage patterns on plants, functional morphology, body size, and the diets of the closest living relatives (taxonomic uniformity), and each link was assigned a level of certainty.
+
+The network has the following properties:
+
+- `name`: the name of the taxon or resource.
+- `group`: the higher-level taxonomic group of the taxon (usually its order, as in "Coleoptera").
+- `certainty`: the certainty of the feeding link, with 1 = high, 2 = intermediate, 3 = low (see the graph property `certainty_key`).
+- `evidence`: the list of types of evidence supporting the link, with codes 1 = taxonomic uniformity, 2 = functional morphology, 3 = gut contents, 4 = damage pattern, 5 = stratigraphic co-occurrence, 6 = body size, 7 = coprolites, 8 = host relationship, 9 = biochemistry and minerals, 10 = track or domicile (see the graph property `evidence_key`).
+- `references`: the list of literature references supporting the link, as indices into the graph property `reference_key`."""
