Carbon dating only
Dinosaur bones with Carbon-14 dates in the range of 22,000 to 39,000 years before present, combined with the discovery of soft tissue in dinosaur bones, indicate that something is indeed wrong with the conventional wisdom about dinosaurs. Kline team of the Glendive Dinosaur and Fossil Museum. Triceratops #2, a very large ceratopsid-type dinosaur excavated in 2007 in Cretaceous clay at 47 02 44N and 104 32 49W in Montana by the O. Outer bone fragments of a femur were tested for C-14. Scrapings were taken from a rib still imbedded in the clay soil of a ranch in CO, partially excavated in 20, in 150 Ma (late Jurassic) strata by C. It can be as high as 20% in normal bone but decomposes over time so that there should be none after ~100,000 years.
Carbon-14 is considered to be a highly reliable dating technique.Researchers have found a reason for the puzzling survival of soft tissue and collagen in dinosaur bones - the bones are younger than anyone ever guessed.Carbon-14 (C-14) dating of multiple samples of bone from 8 dinosaurs found in Texas, Alaska, Colorado, and Montana revealed that they are only 22,000 to 39,000 years old.Senior research scientist Alexander Cherkinsky specializes in the preparation of samples for Carbon-14 testing.He directed the pretreatment and processing of the dinosaur bone samples with the Accelerator Mass Spectrometer, though he did not know the bones were from dinosaurs, and he signed the reports.
