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.

Mantle plumes are the best explanation we have for much of Earth's intraplate volcanism but some remain doubtful despite 50 years of rigorous testing.

Here’s a pretty cool image: Plate 7 from Lull (1919), showing the partial skeleton of Barosaurus YPM 429 (above), compared to the much more complete skeleton of Diplodocus CM84/94 (below). I’ve been pretty familiar with that Barosaurus skeleton diagram since I was about 9 years old, because it’s in Donald Glut’s New Dinosaur Dictionary , which I’ve written about here before.

In Eastern Asia, Jurassic and Cretaceous intraplate volcanism and magmatism differ in their spatial distribution and composition. A combination of plate kinematic and geodynamic models provides clues for their causes.

The largest earthquakes occur at subduction zones, where one plate descends beneath another into the underlying mantle, at a convergent plate boundary. Some subduction zones seem to host more large earthquakes than others (Fig. 1), potentially reflecting the influence of large-scale geodynamic processes, which vary from one subduction zone to the next.

Two days ago, I wrote about what seemed to be an instance of peer review gone very wrong. I’ve now heard from two of the four authors of the paper and from the reviewer in question — both by email, and in comments on the original post — and it’s apparent that I misinterpreted the situation.

THIS POST IS RETRACTED. The reasons are explained in the next post. I wish I had never posted this, but you can’t undo what is done, especially on the Internet, so I am not deleting it but marking it as retracted. I suggest you don’t bother reading on, but it’s here if you want to.

Can communities around domain repositories be used to increase connectivity for researchers and organizations in those communities? The UNAVCO repository suggests that the answer is yes.

Rare Earth Elements are critical for low-carbon transport and energy generation. What are they, how do we find them and extract them ?
