A question I'm often asked is: Why don’t we find human fossils in the sedimentary layers that contain dinosaurs? If dinosaurs and people lived together, why do we find dinosaur fossils but no humans?
Here are two more possibilities that I thought of that might provide an answer…
3 - Humans, unlike animals, would know the properties of water.
For example, they would know that water always finds its lowest point. Animals would not know this. Humans would know to get higher up into the mountains to escape the rising water. Any animals that perhaps went up with them possibly became food for the people.
Also, there were many ripped up
trees floating on the surface of the water. It’s possible that many people lashed trees together and floated for a while. Again, any animals on those trees would have eventually become food for them. Eventually, the people would have died from starvation and from not having fresh water. This scenario would prevent humans from being fossilized in the sediments.
4 - It could also be that liquefaction played a major role in this as well. Liquefaction would occur as the moon would have been going around the planet, causing large tidal effects with no land masses to interrupt the movement of
water.
The pressures in front of and behind the tides lifted and sorted the fossils each time there was a tide. Fossils are basically sorted by density in these events, so it is possible that liquefaction moved whatever human remains there might have been to more surface areas where they would not have fossilized.
