At last, a date for the K/T event 30 Apr 2008 For years people have been telling us the dinosaurs were killed off in an extinction event 65 million years ago. That always seemed a little too even for me. Did they round off, or was there doubt, or what? Now, thanks to a really good piece of detective work reported by Paleoblog, we know it occurred 65.95 million years, give or take 40,000 years, last Thursday. The authors of the study also date the Chixulub impact that age, reinforcing the theory that the asteroid collision killed them all off, and not volcanic eruptions or anything. Paleoblog also gives the link to the paper. Evolution

Epistemology God and evolution 3: The problem of purpose A 13 Apr 201322 Jun 2018 The problem of purpose When Darwin published the Origin, he was lauded by his Christian friend and correspondent Asa Gray, who wrote: “…Darwin’s great service to Natural Science in bringing back to it Teleology: so that instead of Morphology versus Teleology, we shall have Morphology wedded to Teleology” Darwin replied… Read More
Epistemology Evopsychopathy 2: The phylogenetic bracket 7 Dec 20122 Jan 2013 As noted, SB and EP have a very unfortunate tendency to reflect the status quo in their results and research questions. This is not unique to them. History, sociology, other fields of psychology (psychotherapy for gods’ sake!), and in my own profession, ethics, all have this “Pull of Privilege”. Somehow… Read More
So it is really 66 million years. I wonder how long it will take the rest of us to change that in our heads.

“reinforcing the theory that the asteroid collision killed them all off… This possibility has always interested me. It makes me question my atheism. I can actually get down with the possibility that God, having put all His cosmic energies into this Great and Beautiful Thing, which would ultimately give rise to a magnificent celestial being endowed of His own image, ends up with nothing more than a whole lot of big and crazy lizards. I’ve done enough DIY to empathise with His feelings of frustration and failure, and I too have thrown something large and heavy at my creation and then stormed off in a huff. Maybe there’s something in Deism after all.
At last, a date for the K/T event Oh, shoot. I forgot all about it! My tux is at the cleaners. Were you taking her to the Restaurant At The End Of The Universe? Seems appropriate.
That is such a brilliant piece of thinking, and so serendipitous a sediment. But how many studies does it take to change a light bulb?

Hmmm, let’s see. Wouldn’t that put the event at about two days, 14 hours after the Flood? Can’t wait to see the article in ARJ explaining this finding.
“The ratio of argon-39 to argon-39 then provides” … either a very clear hint of the existence of a typo, or a very good estimate of the number “1”.

Not sure where that bit you quote comes from, efrique, but the paper says Ar40/Ar39 ratio in the abstract.

Not sure where that bit you quote comes from Really? It’s smack-dab in the middle of the paleoblog piece. The authors of the study also date the Chixulub impact that age, reinforcing the theory that the asteroid collision killed them all off, and not volcanic eruptions or anything. I’ve long (ever since I read “T. Rex and the Crater of Doom”, a science who-done-it that I highly recommend as an illustration of just how exciting and fun science can be) been fascinated by the wholly unwarranted resistance to the claim that the impact was the direct cause of the extinction. It’s like arguing that Lincoln died, not from a bullet from JWB’s gun, but from an aneurysm that just happened to burst, totally independently, milliseconds earlier. Sure it’s possible, but so is YEC. Hopefully this research will put the issue to rest, but one could have hoped that of the mass of evidence already accumulated.
