is a special issue that focuses on the investigation of dinosaur proteins inside fossil bones.

The last article in the issue presents never-before-seen carbon dates for 14 different fossils, including dinosaurs.

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.

Comparable amounts of radiocarbon showed up in almost 50 total samples.

Defenders of evolutionary time scales will have to assert that the radiocarbon all came from some sort of contamination, where recent or modern carbon somehow crept into all these samples.

The most widely known form of radiometric dating is carbon-14 dating.

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