Carbon dating dinosaur bones. Expiry dates & leave fossils in the ground

How do we know how long ago dinosaurs lived?

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 the archaeological workhorse Because C 14 has such a short half life (radioactively decaying into Nitrogen 14), all original C 14 should have disappeared well before 100,000 years. But
Until recently, Carbon 14 dating was never used to test dinosaur bones, as the analysis is only reliable up to 55,000 years. Scientists never considered it can radiocarbon dating be used to determine the age

A Triceratops was C14 dated three times and the C14 said it was about 33,000 years old. C14 was found in all 7 dinosaur fossils submitted The half life for 14C is approximately 5700 years, therefore the 14C isotope is only useful for dating fossils up to about 50,000 years old.

Radiocarbon in dinosaur fossils proves they are young, How radioactive isotopes estimate age

Carbon 14 has been found in dinosaur fossils. This proves the fossils are young because Carbon 14 has a half life of only 5730 years. Beds that preserve fossils typically lack the radioactive elements needed for radiometric dating. The use of dinosaur bones as "dragon bones" has persisted
