Eh, no, not really, because the article makes clear that this fossil has the rare combination of having been found before modern dating techniques existed, as well as having been treated extra carefully because of its "unique" status, and therefore avoiding some of those dating techniques until recently.
> How could scientists have presumed the dark outline was carbonized soft tissue for so many decades? "This fossil was discovered in 1931 and back then fossils were treated very differently than today," said Rossi. "Application of paints, consolidates and lacquers on fossil bones was the norm, because that was the only way to protect the specimens from further deterioration. It was also sometimes to embellish specimens by making them sleek and shiny. Unfortunately, in the case of Tridentinosaurus, the mechanical preparation did most of the damage and then the application of a black paint created the illusion of a lizard-like animal impression on the surface of the rock."
If anything, I am constantly blown away by how accurately we actually can date things. For example, thanks to dendrochronology[0] we can now often accurately date the exact year prehistoric wooden constructions like buildings or bridges were made, up to almost 14,000 years into the past! And that range will only increase.
