Another rule to abide by to survive in the Southeast Asian jungle: never look back.

My grandfather was in the military and did a bunch of long-range jungle patrols during the Insurgency years. He doesn't talk about it much but he says there's a code every member of the patrol has to abide by before "trespassing into the realm of the others".

First rule of surviving Southeast Asian supernatural encounters: if you see, hear, or smell something odd, for your own sake never point it out until it's passed.

The second is if you find something odd, never pick it up and leave it as it is.

The whole thing isn't a single fossil, but it is made of fossilised corals, shells, and carbonate minerals that are deposited in between them as mud.

If you can get yourself to any limestone outcrop near you there's a good chance you'll find fossils in them
