Imagine the surprise when every piece of ancient carbon tested has contained measurable quantities of radiocarbon4 Fossils coal oil natural gas limestone marble and graphite from every Flood-related rock layerand even some pre-Flood depositshave all contained measurable quantities of radiocarbon Figure 2. The heat and pressure caused by contact metamorphism would distort and destroy the existing fossils in the limestone as it changed.
