They might classify that interval as the Bipedal Primate Period, and you lived in the Era of Petroleum, do distinguish you from other fossil remains that came from earlier civilizations of Bipedal Primates. In addition, Tectonic events were occurring such as continental breakups that resulted in a lot of tensional faulting and basin creation, and the red beds were deposited in these basins.

So we know these events happened during the same interval of time, and that any fossils found in those sediments lived during the time of the events and are therefore Triassic in age.

They could burrow into an underlying layer and become fossilized there, but in nearly all cases this would be accounted for in the "age range" assigned to the fossils of the creatures.Basically from the Geologic Law of Superposition which states, the sedimentary bed on the bottom is the oldest.This comes from the fact that sediments are laid down in water or on the surface of the earth in layers so the first is the oldest and next is younger.For instance, if a volcano erupts, like the super volcano that blew up to form the caldera in which Yellowtone Nat'l Park sits, then it left a lot of ash scattered over North America.THAT was a discrete instant in time geologically since the explosion occurred and the ash fall lasted for years not hundreds or millions So we can identify that layer of ash in the rock record and say..happened in such and such time.
