Seeing how many monsters in the Oilwell Basin are pretty large makes me wonder like what the possibile food chain is like. Like I know oil in our world is liquefied plankton fossils but in the MH world I wonder if the oil we see could be like millions of tiny invertebrates
Well if it wasn’t actually made of crude oil then it probably wouldn’t be extremely flammable, but it definitely can form the basis of an ecosystem. Plenty of bacteria and fungi can easily consume petroleum and hydrocarbons, so it might be that instead of plants forming the basis of the ecosystem in the oilwell basin, bacteria and fungi are the primary producers.
