A team of researchers gave a presentation at the 2012 Western Pacific Geophysics Meeting in Singapore, August 13–17, at which they gave 14C dating results from many bone samples from eight dinosaur specimens. Although the fossils were geologically dated to be over 65 million years old (Cretacious-Jurassic age), C14 dating showed they were less than 40,000 years old.

Something is not right here. There cannot be that much difference between the Geological date, and the Radiocarbon date. After millions of years of being buried, there should be no Carbon 14 left.

The following is the abstract and results C14 dating:

(a)

Acro (Acrocanthosaurus) is a carnivorous dinosaur excavated in 1984 near Glen Rose TX by C. Baugh and G. Detwiler; in 108 MA Cretaceous sandstone – identified by Dr. W. Langston of Un. of TX at Austin.

Allosaurus is a carnivorous dinosaur excavated in 1989 by the J. Hall, A. Murray team. It was found under an Apatosaurus skeleton in the Wildwood section of a ranch west of Grand Junction CO in 150 Ma (late Jurassic) sandstone of the Morrison formation.

Hadrosaur #1, a duck billed dinosaur. Bone fragments were excavated in 1994 along Colville River by G. Detwiler, J. Whitmore team in the famous Liscomb bone bed of the Alaskan North Slope – validated by Dr. J. Whitmore.

Hadrosaur #2, a duck billed dinosaur. A lone femur bone was excavated in 2004 in clay in the NW ¼, NE ¼ of Sec. 32, T16N, R56 E, Dawson County, Montana by the O. Kline team of the Glendive Dinosaur and Fossil Museum. It was sawed open by the O. Kline, H. Miller team in 2005 to retrieve samples for C-14 testing.

Triceratops #1, a ceratopsid dinosaur. A lone femur bone was excavated in 2004 in Cretaceous clay at 47º 6’ 18” by 104º 39’ 22” Montana by the O. Kline team of the Glendive Dinosaur and Fossil Museum. It was sawed open by the O. Kline, H. Miller team in 2005 to retrieve samples for C-14 testing.

Triceratops #2, a very large ceratopsid-type dinosaur excavated in 2007 in Cretaceous clay at 47' 02" 44N and 104' 32" 49W by the O. Kline team of Glendive Dinosaur and Fossil Museum. Outer bone fragments of a femur were tested for C-14.

Hadrosaur #3, a duck billed dinosaur. Scrapings were taken from a large bone excavated by Joe Taylor of Mt. Blanco Fossil Museum, Crosbyton TX in Colorado in Cretaceous strata.

Apatosaur, a sauropod. Scrapings were taken from a rib still imbedded in the clay soil of a ranch in CO, partially excavated in 2007 and 2009, in 150 Ma (late Jurassic) strata by C. Baugh and B. Dunkel.

(b)

GX is Geochron Labs, Cambridge MA, USA; AA is University of Arizona, Tuscon AZ, USA; UG is University of Georgia, Athens GA, USA; KIA is Christian Albrechts Universität, Kiel Germany.

(c)

AMS is Accelerated Mass Spectrometry; Beta is the conventional method of counting Beta decay particles.

(d)

Bio is the carbonate fraction of bioapatite. Bow is the bulk organic fraction of whole bone; Col is collagen fraction; w or ext is charred, exterior or whole bone fragments; Hum is humic acids.

Bioapatite is a major component of the mineralised part of bones. It incorporates a small amount of carbonate as a substitute for phosphate in the crystal lattice.

Charred bone is the description given by lab personnel for blackened bone surfaces.

Collagen: Proteins that are the main component of connective tissue. It can be as high as 20% in normal bone but decomposes over time so that there should be none after ~100,000 years. Yet it is found in four-foot long, nine-inch diameter dinosaur femur bones claimed to be greater than 65 million years old. The “Modified Longin Method” is the normal purification method for bone collagen. Dr. Libby, the discoverer of Radiocarbon dating and Nobel Prize winner, showed that purified collagen could not give erroneous ages.


Mostly when you go to conferences of this kind, the scientists list their affiliation by university or research institution - the all list their university by 'Paleo Group'. A quick Google brings up their web site: http://www.dinosaurc14ages.com/contact.htm, and also some of their other affiliations:

http://www.creationtruth.org/digs.html

'Creationtruth' eh? a bit of a giveaway.

I tried following the link to 'conferences', but got a '404' from 'Hostgator, build your web site today for 1 cent'. Strange that the university or institute that they work for doesn't host their site for them.

I went to 'who are we' - strangely, it doesn't tell you who they are. When trying to assess the credibility of a source, it's good to have a publication history, some idea of affiliation and so on. Sadly here there is none.

As for the conference, I could find none called the 'Western Pacific Geophysics Meeting'. Co-incident with the date and location was the 'AOGS-AGU (WPGM) Joint Assembly'. 'AOGS' is the 'Asia Oceana Geophysics Society', 'AGU' is the 'Amaerican Ceophysics Union'. The conference seems to have a program comittee in place, though I not from their website that they only review abstracts, not the finished paper. I would think that this team of 'researchers' is going to have a hard time getting their news across, in the face of counter evidence in rigorously peer reviewed journals. Maybe they should have gone for 'Nature' or something like that, unless you can think of a reason why they should not have.

All seems in order, Bob. What's the problem?

I hand reared a number of dinosaurs. So, Phil MUST be spot on. Heck they even had scientific dinosaur names!

"Dumetella carolinensis"

and my favorite: Turdus migratorius

Both were vicious predators, I fed them chopped meat until they were old enough to kill on their own. And good for me I let them go at the end of Summer...
