I’m pretty sure that our old friend the AMNH Barosaurus was the first sauropod skeleton even mounted in a rearing pose.

(Does anyone know of an earlier one? That would be fascinating!)

But what other mounted sauropods have been placed in a rearing posture, with both forefeet off the ground? I know of four others. First, the rearing Diplodocus at the Museum of Science and Innovation in Tampa, Florida, that we discussed in detail in Taylor et al. (2023:80–82):

Strangely enough, the other three are all individuals of Camarasaurus, an ugly four-square sauropod whose centre of gravity was well forward of the acetabulum in normal posture, and which would have found rearing much more difficult than in diplodocids. My guess is that’s just because Camarasaurus is so abundant that there are a lot of mounted skeletons out there, and some have been mounted in rearing postures because, well, why not?

Here is one from the Wyoming Dinosaur Centre in Thermopolis:

(I can’t find a good photo of this mount from the front or the side: if anyone can, please let me know in the comments.)

The next is in the US National Museum (USNM), otherwise known as the NMNH, otherwise known as the Smithsonian. It’s on the right of this photo:

And finally, as I was putting this post together, I stumbled across this mount at the Naturalis Biodiversity Center in Leiden, the Netherlands:

I know nothing about this one, and would welcome any details.

In fact, I don’t know much about any of the three rearing camarasaurs. Can anyone tell me, for example, when they went up? And whether the AMNH Barosaurus was a conscious inspiration?

And the $64,000 question: does anyone know of other rearing sauropod mounts?
