Carbon-14 Datable Materials Samples that have been radiocarbon dated since the inception of the method include charcoal, wood, twigs, seeds, bones, shells, leather, peat, lake mud, soil, hair, pottery, pollen, wall paintings, corals, blood residues, fabrics, paper or parchment, resins, and water, among others.

Can wood be used in radiocarbon dating?

Radiocarbon Dating Because wood can be dated directly and by radiocarbon, scientists used bristlecone pines to calculate a new calibration curve, and convert radiocarbon results into accurate calendar dates.

Why cant carbon 14 dating be used on dinosaur remains choose the best answer?

To determine the age of a dinosaur fossil, carbon dating can never be used. By the time a dinosaur fossil was found, any carbon-14 the organism would have taken up and incorporated into its tissues during its life, would have decayed too much to be useful as a tool to determine its age.
