Mandschurosaurus (Age of the Dinosaurs by PNSO)

Beijing-based PNSO (Peking Natural Science and Art Organization) made a splash this year with the release of several large hollow vinyl figures. Besides being imposing due to their size, the new figures are notable for their high level of detail and the unconventional species choices. Today we’ll look at their Mandschurosaurus, the first plastic figure of this genus ever released.

Mandschurosaurus is not the most famous dinosaur, but rather an obscure genus known from just a few bones discovered in the Amur region of Russia’s far east. The figure is bulky, like the others in its line, about 40 cm long measured along the spine. I couldn’t find reliable length estimates for the animal, so to figure out the scale I actually found a copy of the holotype description in a Soviet paleontology journal (thanks, interlibrary loan and Stanford University!). Incidentally, the author, A.H. Рябинин, died in 1942 and under Russian copyright law his work is now in the public domain.mandschurosaurus_amurensis
The description is mostly in Russian, with parts in English and French. But all I needed was some measurements, and numbers are a global language! I got measurements from both the original specimen and the toy for three bones:

scapula: 76 cm, 4.8 cm on the toy
ulna: 62.4 cm, 3 cm on the toy
tibia: 90 cm, 5.2 cm on the toy

On the toy they’re not quite all to scale with each other, but if you average them together, this figure is about 1:18. That’s a big hadrosaur!

It’s a very nicely sculpted figure, although the preceding measurements suggest some minor proportion problems. The entire piece is painted in various shades of brown, with a glossy finish. It’s slightly paler underneath, with a finely detailed wrinkled texture with tubercles and spiky scales along the back and a nice saggy dewlap.

The head is not well known for Mandschurosaurus, so this one is sculpted to resemble a generic crestless hadrosaur. The eyes are the sole spot of color, painted a cool blue.

This hollow figure is molded in multiple pieces, and assembled with glue. Despite the reasonably nice paint job, the seams are still visible around the midsection and across the lower thigh. I don’t find the seams terribly distracting, but your mileage may vary. My copy stands well on its own, but I have heard from other buyers that it can be unstable. It comes on a clear plastic support that you can use to keep it steady, or you can prop it up against another dino on your shelf.

This might be a good figure for older kids, but probably not for the very young, since the paint chips easily and one incautious child could bonk another one pretty good. I get the impression that it is aimed more at adult collectors, and the price reflects that. It’s an attractive replica that looks very impressive on the shelf, and depicts a unique animal, so I’d recommend it for any fan of hadrosaurs, expert sculpting, or large-scale dinosaurs in general.
