The woody internal structure was clearly evident, thus the samples were not the remains of roots that had grown into this weathered rock from trees on the present land surface.When sampled, the fossil wood readily splintered, diagnostic of it still being ‘woody’ in spite of its impregnation with iron minerals during fossilisation.

Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow.
Mr Miller told Ancient Origins that it is always desirable to carbon-14 date several fractions to minimize the possibility of errors which Miller requested and that essential concordance was achieved in the 1000's of years as with all bone fractions of ten other dinosaurs.
Triceratops, a name meaning “three-horned face”, is a genus of herbivorous ceratopsid dinosaur that is said to have first appeared during the late Maastrichtian stage of the late Cretaceous period, about 68 million years ago in what is now North America, and became extinct in the Cretaceous–Paleogene extinction event 66 million years ago.
Mr Miller sent the sample to the University of Georgia, Center for Applied Isotope Studies, for this purpose.
The sample was divided at the lab into two fractions with the “bulk” or collagen break down products yielding an age of 33,570 ± 120 years and the carbonate fraction of bone bioapatite yielding an age of 41,010 ± 220 years [UGAMS-11752 & 11752a].
A Triceratops brow horn discovered in Dawson County, Montana, has been controversially dated to around 33,500 years, challenging the view that dinosaurs died out around 65 million years ago.
