Figure 5 The proportional distribution of insects identified to order from the Paleoburn, where insects are mineralized as iron oxides, and Anvil Points, where insects are keroginized as carbonaceous compressions. Although eight orders are shared between

. The beetle is made of iron oxide, but oxygen is not shown due to its ubiquitous presence in all mineral phases. B, Anvil Points thrips APK-M3 with EDS maps for iron, silicon, and carbon. The keroginized insect shows enrichment in carbon and a deficiency in silicon
