Radiometric dating error margin

Before more precise absolute dating tools were possible, researchers used a variety of comparative approaches called relative dating.

Until the 18th century, this question was principally in the hands of theologians, who based their calculations on biblical chronology.The preferred method of dating dinosaur fossils is with the radiometric dating method.And the result of this accepted method dates dinosaur fossils to around 68 million years old. Its half-life ($t_$) is only 5,730 years—that is, every 5,730 years, half of it decays away.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. Different cultures around the world record time in different fashions.

According to the Gregorian calendar, it is the year 2009 AD. The Kaliyuga Hindu Calendar maintains it is 5110, the Islamic calendar 1430 and the Persian, 2630.

Lord Kelvin and Clarence King calculated the length of time required for the Earth to cool from a white-hot liquid state; they eventually settled on 24 million years.

James Joly calculated that the Earth’s age was 89 million years on the basis of the time required for salt to accumulate in the oceans.

Dinosaurs are not dated with Carbon-14, yet some researchers have claimed that there is still Carbon-14 in the bones. Do these data indicate that a more accurate method needs to be derived?

What solutions are available for increasing accuracy of the tests? From the source linked above: Carbon-14 is considered to be a highly reliable dating technique.

The theoretical limit for C-14 dating is 100,000 years using AMS, but for practical purposes it is 45,000 to 55,000 years.
