What Happens When You Get Cited by Young Earth Creationists

This is an issue that has plagued Stephen Jay Gould and Niles Eldredge in the past, when you get misquoted by a young-earth creationist.  Now, Dave Hone has written a column for the Guardian about how this has affected him personally:
Recently, I spotted a short creationist essay that had cited a paper of mine on various recent pterosaur finds and which was supposed to be some kind of response to an article written for the Observer. The creationist piece attempted to argue that these new discoveries helped support the idea that these pterosaurs were made by a creator. Oddly enough, I was left rather unconvinced, not least because of the obvious mangling of some fairly simple and very well-known history that contradicts the arguments presented in some delightfully ironic ways.

For a long time, pterosaurs were regarded as rather inept fliers and little more than unusual gliding reptiles, but this view has been overturned with more modern studies. In his piece on how our understanding has changed with new research, palaeontologist Dr Mark Witton wrote in the Observer that in the past, pterosaurs had been regarded as little more than “gargoyles with lanky limbs”. Our valiant creation-support correspondent then asks “Was th[is] description… a result of mere evolutionary speculation? Based on seeing pterosaur fossils occur in strata below other flying vertebrates, perhaps evolutionists reasoned that pterosaurs evolved first and therefore represented evolution’s initial, clumsy attempts to produce large flyers.”

Ah. Now, you see, there are a fair few issues here. Although the idea of changing species had been around for many years, there’s a good reason that biologists give so much credit to Darwin and On the Origin of Species for laying down the foundations of natural selection and ideas about changes over time. Darwin’s work was published in 1859, but pterosaurs were discovered around 1780 (see Wellnhofer, 2008; a point made in Witton’s piece but mysteriously overlooked). Early thoughts about them could therefore hardly have been influenced by “evolutionists” as there can’t really have been many around. Indeed, early researchers had considered pterosaurs might be marsupials and amphibians, or perhaps swimming animals (Wellnhofer, 1991) before most settled on flying reptiles.
Because the writer does not have the background to properly assess the prehistory of pterosaurs, he makes rudimentary, silly mistakes that destroy his own argument. This is, sadly common in young-earth creation circles and I have dealt with it with regards to the inept posts on AiG's site by David Menton and Elizabeth Mitchell, in which, clearly not knowing anything about the fossil record, they make suspect claims about the individual fossils that do not bear up under close analysis. 

Another hatchet job by AiG.

A YEC Icon of Faith is Invalidated

Joshua Kritsch at Vocative reports on an article that has been written for the Journal Antiquity, called Death of a Pterodactyl.  Here is what he writes:
Along the sloping walls of the Black Dragon Canyon in Utah, there’s a curious rock painting that looks remarkably like a flying dinosaur. Creationists say it’s proof that humans and pterodactyls once coexisted. But now, in a paper published in the journal Antiquity, archaeologists have revealed that the “dinosaur” is actually a time-worn depiction of humans, a snake and some sheep.
“What was supposed to be one wing of this pterodactyl is actually two little four-legged animals,” Paul Bahn, a freelance archaeologist and coauthor of the paper, told Live Science. “The so-called head and beak and neck of the pterodactyl [are] actually a human figure, with its spindly legs and its two arms stretching out.”
Honestly, I had not heard this claim, but as there are thousands of little young earth creationism claims out there, that is not surprising. How was this claim refuted?  From the abstract:
A new study using portable X-ray fluorescence refutes this ill-founded interpretation and reveals a scene characteristic of Barrier Canyon style, featuring an anthropomorphic figure. By removing interpretational bias, the new technology finally lays to rest the Black Dragon Canyon pterosaur.
As the Rock Man says: “You hear what you want to hear, and you see what you want to see.”
