As iconic as Brachiosaurus altithorax is, it’s known from surprisingly little material.

Here are the humerus and ulna of a pelican, bisected: {.alignnone .size-full .wp-image-14798 loading=“lazy” attachment-id=“14798” permalink=“http://svpow.com/2018/03/17/bisected-pelican-arm-bones-of-the-oxford-museum-of-natural-history/img_0904/” orig-file=“https://svpow.files.wordpress.com/2018/03/img_0904.jpg” orig-size=“4000,3000” comments-opened=“1”

This will be all too short, but I can’t let the publication of a new giant sauropod pass unremarked.

Well, who knew? There I was posting images of “Pelorosaurus” becklesi‘s humerus, radius and ulna, and skin impression. There I was saying that this beast is due a proper description, and warrants its own generic name.

It’s an oddity that in eight years of SV-POW!, we’ve never written about one of the best of all the Wealden-formation sauropod specimens: the forelimb and associated skin impression NHMUK R1870 that is known as “ Pelorosaurus ” becklesii . Let’s fix that.

Continuing with what seems to have turned out to be Brachiosaur Humerus Week here on SV-POW! (part 1, part 2, part 3), let’s consider the oft-stated idea that brachiosaurs have the most slender humeri of any sauropod.
