Small undescribed theropod from the lower Jurassic of Lufeng.

The museum is filled with tons (literally) of Lufengosaurus specimens. Labelled varyingly as L. huenei, L. magnus, and L sp. These all probably represent different onotgenetic stages of L. huenei.

As awesome as this huge mount looks, I noticed that the hips  had to be seriously dislocated to get it into this position.

As a result of my trip to this  museum my mental image of Lufengosaurus has been emended from “smallish”  to “huge-ish.” Some of these things were massive

This is what happens when you do a drawing dictated by a hyper-active 8 year-old.

This sacrum from the Lower Jurassic of Lufeng may well represent the oldest stegosauria remains on display anywhere.  If anyone reading this knows otherwise,  I ‘d appreciate being told about it.

Here’s an awesome allosauroid skull from the Middle Jurassic of Yuanmou, Yunnan. The English portion of the display tag refers to this specimen, ZLJ0115, as “Yuanmouraptor.” However, if I understand the Chinese portion correctly, this critter is still undescribed.

The World Dinosaur Valley Museum had several mounted skeletons of the interesting theropod, Sinosaurus triassicus.  Up until a few days ago, this critter was stuck with the erroneous moniker, Dilophosaurus sinensis.

This specimen with seemingly reduced crests caught my attention. Not sure if this was the result of sexual dimorphism, ontogenetic variation or an artifact of preservation. As this critter was about the same size as the other specimens, I don’t this variation was due to ontogeny. The specimen was mounted more than a couple of meters overhead, so it was impossible to get a better look at it. I’d greatly appreciate it if anyone familiar with the specimen could tell me more about it.
