The process generally used to date a fossil is circuitous and subject to differing interpretations.It has involved tracing the related sedimentary rock layer horizontally from the place where the fossil in question was found to a place where it is underlain or overlain (or both) by igneous rock.Apparently there was some back and forth about some fossils with Carl Zimmer.Anyway, Don Prothero commented about it and this is a great quote for a variety of reasons.Next, you need a location where the fossils are between two layers that can be dated.Psomas paleontologist Melissa Macias has discovered the bone fragments of a fossilized whale while monitoring work at the Frank R. At more than 40 feet long, this is the biggest sperm whale found in Orange County.

A Blood-Filled Fossil Researchers recently examined a spectacular mosquito fossil containing still-bloody remnants within its body.Not the least of which is that it deftly refutes the creationist claims that using index fossils to date rock layers is circular reasoning.Their logic (which is wrong) goes like this: Fossils are x millions of years old because they are in this rock layer.The study authors wrote, “The combination of these two determinations indicates that the porphyrins [dark red pigments] are derived from the oxygen-carrying heme moiety of hemoglobin”—real blood.

Secular researchers have detected hemoglobin remnants like these in several other species, including tyrannosaur, hadrosaur, and mosasaur fossils.But in standard studies, no age assignment is ever accepted unless it conforms to the "millions of years" doctrine of evolutionary earth history.
