Senior research scientist Alexander Cherkinsky specializes in the preparation of samples for Carbon-14 testing.He directed the pretreatment and processing of the dinosaur bone samples with the Accelerator Mass Spectrometer, though he did not know the bones were from dinosaurs, and he signed the reports.Critics charged that the findings were mistaken or that what she called soft tissue was really biofilm produced by bacteria that had entered from outside the bone.Schweitzer answered the challenge by testing with antibodies.

Carbon-14 (C-14) dating of multiple samples of bone from 8 dinosaurs found in Texas, Alaska, Colorado, and Montana revealed that they are only 22,000 to 39,000 years old.

Due to this, it is not possible to do carbon dating at home unless you happen to have a mass spectrometer lying around. The half lives of carbon isotopes are derived by studying their radioactive decay.

For carbon dating, the isotope used is Carbon-14, which has a half life of 5,700 years.

He said that his team and the laboratories they employed took special care to avoid contamination.

That included protecting the samples, avoiding cracked areas in the bones, and meticulous pre-cleaning of the samples with chemicals to remove possible contaminants.

Schweitzer herself wonders why these materials are preserved when all the models say they should be degraded.
