But careful analysis by researchers has substantiated the presence of Carbon 14 in dinosaur bones.Critics suggested that the samples became contaminated with modern Carbon 14. al., “Measurable , August 2003.) In 2012, researchers analyzed multiple dinosaur bone samples from Texas, Alaska, Colorado, and Montana.

Carbon 14 (C-14) dating is used to establish the age of skeletons, fossils, and other items composed of material that was once alive.

Very precise analysis from modern mass spectrometers can establish the date the living material in the sample stopped taking in carbon from the environment (the point of death).

Because C-14 has such a short half-life (radioactively decaying into Nitrogen 14), all detectable C-14 should have disappeared well before 100,000 years.

an interveiw with the people who were involved in the find and research on the t-rex bone that has blood and elastic tissue in it.

The evidence that hemoglobin has indeed survived in this dinosaur bone (which casts immense doubt upon the 'millions of years' idea) is, to date, as follows: The tissue was coloured reddish brown, the colour of hemoglobin, as was liquid extracted from the dinosaur tissue. Chemical signatures unique to heme were found in the specimens when certain wavelengths of laser light were applied.

Because it contains iron, heme reacts to magnetic fields differently from other proteins—extracts from this specimen reacted in the same way as modem heme compounds.To ensure that the samples had not been contaminated with certain bacteria which have heme (but never the protein hemoglobin), extracts of the dinosaur fossil were injected over several weeks into rats.If there was even a minute amount of hemoglobin present in the T.Rex sample, the rats' immune system should build up detectable antibodies against this compound.This is exactly what happened in carefully controlled experiments.Evidence of hemoglobin, and the still-recognizable shapes of red blood cells, in unfossilized dinosaur bone is powerful testimony against the whole idea of dinosaurs living millions of years ago.
