Carbon dating dino bones
The evolutionist interprets this as meaning that the species lived and died over a relatively short time (perhaps a few million years).
On the other hand, the same fossil species must have a narrow vertical distribution, that is, only be buried in a few rock layers.The staff at these laboratories were not told exactly where the samples came from, or their supposed evolutionary age, to ensure that there would be no resultant bias. Fossil wood in the top section of the Marlstone Rock Bed exposed in the south wall of the Hornton Quarries at Edge Hill.The pen is not only for scale, but points to an end-on circular profile of a belemnite fossil sitting directly underneath the fossil wood (sampled as UK-HB-1). Both laboratories used the more sensitive accelerator mass spectrometry (AMS) technique for radiocarbon analyses, recognised as producing reliable results even on samples with minute quantities of carbon.Such a criticism is totally unjustified (see aside two). Four belemnite fossils, probably Acrocoelites, recovered from the top section of the Marlstone Rock Bed in the Hornton Quarries at Edge Hill (pen for scale).
These cylindrical skeletal shells of the belemnites which taper to apices are called rostrums (ref.No detectable C would remain in wood older than about 50,000 years.
