We’ve seen the humerus of the Wealden-supergroup putative titanosaur “ Pelorosaurus ” becklesi . We’ve seen the bones of the forearm, the radius and ulna. That’s it for bony remains: no other bones have been found.

It’s been a while since we looked at everybody’s favourite partial dorsal vertebra, and there may be those who feel we’ve said all that can be said about it, but there is one feature of Xenoposeidon that we’ve never really highlighted here and which is well worth a look.

Happy Xenoposeidon day!  Today, November 15, 2008, is the one-year anniversary of the publication of Xenoposeidon Taylor and Naish 2007. By happy coincidence, I’ve just been sent a courtesy copy of Kids Only , a new guide-book for the Natural History Museum … and there is Xenoposeidon on page 5, exemplifying dinosaur diversity.  Rock!

Today, we bring you the long-overdue third installment in everyone’s  favourite Mystery Sauropod Dorsals serial, our trawl through the NHM’s collection of mostly isolated elements from the Wealden Supergroup. Many of these elements are too bashed up to be diagnostic (with the Xenoposeidon holotype R2095 being an honourable exception).

In this article I’d like look at something that I’ve just spoken about at a conference: the ‘Dinosaurs – A Historical Perspective’ meeting held in London on May 6th and 7th (my thoughts on the conference can be found here and here). Mike attended too (and, like me, gave a talk), but Matt couldn’t make it. Anyway…

Again, another exclusive peek at an interesting specimen: the MIWG.7306 vertebra, aka ‘Angloposeidon’ (Naish et al . 2004). Apologies if, by now, you’re bored of my show-casing of this specimen, but – not only is it the only sauropod vertebra of which I personally have multiple unpublished images – it is also a really nice demonstration of the fact that, even in just a single vertebra, there are multiple interesting, bizarre,

It’s a lonely night here at the Fortress of Sauropoditude. Darren is off at one of his numerous conferences, and Mike is in hiding, trying to avoid the reality that 4% of a millennium has passed since he was loosed upon the world. I gave the serfs the night off, which means it’s just me here in this lonely tower, surrounded by arcane devices, mouldering tomes and piles of ancient bones.

A hat-tip to Paul Barrett, who’s reminded us that technically we’re not supposed to be using photographs of Natural History Museum specimens — at least, not without acknowledgement.

Things are pretty quiet at SV-POW!

Inspired by Mike’s recent post on the interior of Chondrosteosaurus from the Isle of Wight’s Wessex Formation, what could I do but weigh in yet again with one of my most-loved specimens: the beauty that is MIWG.7306 (aka ‘Angloposeidon’), a big brachiosaurid also from the Wessex Formation (Naish et al . 2004). As mentioned previously, it’s perhaps intuitively surprising that one of the most useful things about MIWG.7306 is that
