Human implements in the lower layers reveal man’s presence going back to early in the fossil record.
Of course human and dinosaur footprints (trace fossils) in the same rock layer are direct evidence of coexistence, indicating both walked through those sediment before they hardened.
The carbon that is part of their bodies starts to radioactively decay, bringing the ratio of carbon to carbon down.
So by looking at this ratio in a fossil sample, and knowing the half-life of carbon, we can get an estimate of the age of the specimen.
The paleontological support for dinosaurs co-existing with man involves collapsing the evolutionary timescale from both directions.
Clues in the dinosaur bones themselves show they are not millions of years old.
Animals and plants incorporate carbon which they get from their food or from carbon dioxide into their bodies as part of the various organic molecules that make up their cells and other structures.
So the amount of carbon is exponentially decreasing over time.Darwin did however only make fleeting reference to Gibraltar 1 in the 1871 Descent of Man.The original find was done in a time where the palaeontological dating was still in its infancy, and no stratigraphic information was supplied with the skull, making dating at best guesswork.And the increasing number of “modern” fossils discovered alongside the dinosaurs is further evidence that the evolutionary timeline is all wrong.The desire to push the boundaries has been a motivator in many a daring expedition, testing the human spirit and physical abilities to the utmost.
