Fossils can't form in the igneous rock that usually does contain the isotopes.

The extreme temperatures of the magma would just destroy the bones.

Because radiocarbon decays relatively quickly, fossils that are even 100,000 years old should have virtually characters repeatedly mention "million years ago" in the context of their dinosaurs.

In the movie, fictional scientists essentially resurrect and genetically redesign dinosaurs, pterosaurs, and even a giant mosasaur—creatures supposedly extinct for 65-75 million years.

The CRSQ study authors tested seven dinosaur bones, including a from Montana, hadrosaurids, a cartilaginous paddlefish, a bony fish, and fresh-looking wood and lizard bones from Permian layers in Canada and Oklahoma.

Five different commercial and academic laboratories detected carbon-14 in all the samples, whether from Cenozoic, Mesozoic, or Paleozoic source rocks. The team also compared the results to several dozen published carbon-14 results for fossils, wood, and coal from all over the world and throughout the geologic column.

This information has also helped determine the age of the Earth itself.

While the oldest known rocks on Earth are about 3.5 billion years old, researchers have found zircon crystals that are 4.3 billion years old [source: USGS].

To determine the ages of these specimens, scientists need an isotope with a very long half-life.
