Radiocarbon dating can also be difficult if the bones are very small or fragmentary.
They were amazed when radiocarbon dating showed the quiver to be 4, 700 years old.
Other artefacts the team examined included 14 stone tools, which were radiocarbon-dated to between 2090 and 2540BC.

Michael Petraglia, professor of human evolution and prehistory at the University of Oxford has been working on the radiocarbon dating at Al Magar.
Those elevated levels of radiocarbon were tracked carefully, and they began to drop off quickly after a test ban treaty was signed in 1963.
Radiocarbon dating found the skull was from the peak of the last Ice Age ruling out it was a cave bear, or a brown bear.

Those that we did take were used for radiocarbon dating and palaeodietary analysis, as well as analysis of the gut contents and hair, amongst other items.
There are people who believe that the Shroud of Turin wrapped His body, others who stand by a radiocarbon analysis pointing to an origin circa 1300.
It was also found to be a burial site and the bones of four people found there have been radiocarbon dated to being between 4, 515 and 4, 720-years-old.

Butz contacted scientists at a laboratory in Miami that specializes in radiocarbon dating who suggested he first conduct a simple test to determine if the soot stains occurred from more recent fires.
Butz said the Miami lab's radiocarbon tests recently revealed the fires that caused the soot stains occurred between A.D. 1410 and 1450, about two centuries before Europeans began arriving in the area.
Unlike traditional radiocarbon dating, which can be bought off the shelf, Dr Bayliss reckons it takes between three and four years to train a graduate researcher to use the new technique properly.
Unlike archaeological radiocarbon dating based on the fixed rate of decay of the carbon-14 isotope, there is simply no fixed rate of decay of basic vocabulary, which would allow us to date ancestral proto-languages.
Childe, a disillusioned Stalinist, committed suicide in 1957, soon after the Hungarian Uprising and just as radiocarbon dating was transforming the study of archeology, but many of his ideas have survived to the present day.
By examining these samples for the presence of radiocarbon, the developer of a particular drug can see whether the active ingredients are absorbed into the body and, if they are, how long they persist there.
Using a combination of modern physics tools--including three-dimensional, high-resolution X-ray, radiocarbon dating with accelerator mass spectrometry, and infrared spectroscopy--the researchers analysed the tooth to determine the age and composition of a resinous filling detected inside.
Radiocarbon dating, radiological evidence, DNA and bone analysis and archaeological result confirmed the remains found under the parking lot, the former site of Grey Friars church, were those of Richard III, researchers at University of Leicester told reporters Monday.
