My Oct. 13 National Fossil Day public lecture, “Lost Giants of the Jurassic”, for the Museums of Western Colorado – Dinosaur Journey is now up on their YouTube channel. First 48 minutes are talk, last 36 minutes are Q&A with audience, moderated by Dr. Julia McHugh. New stuff from the 2021 field season — about which I’ll have more to say in the future — starts at about the 37-minute mark.
Last time, we looked at the difference between cost, value and price, and applied those concepts to simple markets like the one for chairs, and the complex market that is scholarly publication. We finished with the observation that the price our community pays for the publication of a paper (about $3,333 on average) is about 3–7 times as much as its costs to publish ($500-$1000)? How is this possible?
We have a tendency to be sloppy about language in everyday usage, so that words like “cost”, “value” and “price” are used more or less interchangeably. But economists will tell you that the words have distinct meanings, and picking them apart is crucial to understand economic transaction. Suppose I am a carpenter and I make chairs: The cost of the chair is what it costs me to make it: raw materials, overheads, my own time, etc.

Two and a half years ago, I posted a glorious hemisected hen, taken (with permission) from a poster by Roberts et al. 2016, and supplied by Ray Wilhite, best known in this parish for his work on sauropod appendicular material. At the end of that post, I blithely promised “More from this poster in a subsequent post!”, and then — predictably — forgot all about it. My apologies.
On Thursday, I took the family to the Cotswolds Wildlife Park, a rather lovely zoo just over an hour away from us in Burford, Oxfordshire. Somehow I’d never even heard of this place until we passed a sign for it on the A417 a few weeks ago.
In mammals — certainly the most-studied vertebrates — regional differentiation of the vertebral column is distinct and easy to spot. But things aren’t so simple with sauropods.
Various Internet rumours have suggested that the Archbishop is a super-giant sauropod one third larger than the mounted Giraffatitan specimen MB.R.2181 (formerly HMN SII). This is incorrect.
