This bit speaks to both why geologists commonly see coal deposits within certain strata and not others (read: time periods), and why other "fossil fuels" are likewise associated with certain epochs. Our picture of the ancient past continues to develop; feeling around for shapes in the dark has demonstrated what we once thought a snake to be the trunk of an elephant, "best" understandings adapted or dispensed with when "better" is reckoned- and when we can, tested. The terrestrial animal explanation appealed within the confines of our understanding and imaginative needs of the time- and that's OK; as consideration expanded, the notion was shed like old skin, becoming yet another constituent of folk lore and that enduring oily sludge that is meme culture.
