Sinocoelurus

Sinocoelurus (meaning "Chinese hollow tail", in reference to location and to relate the new genus to the North American Coelurus) is a genus of theropod dinosaur from the Oxfordian-?Tithonian-age Upper Jurassic Kyangyan Series of Sichuan, China. It is an obscure tooth taxon.

History

Famous Chinese paleontologist Yang Zhongjian (in older references his name is given as C. C. Young) named this genus from IVP AS V232-234, a group of four isolated partial teeth found near Weiyuan, Guangyuan, Sichuan Basin. He described them as "long, slender, moderately curved and compressed; ridged anterior and posterior sides with no trace of serrations; enamel very thin".[1] He considered the genus to be "coelurosaurian", which at that time meant a small theropod. The most distinctive characteristic of these teeth was their lack of serrations.[2]

Because of the small amount of material, Sinocoelurus has attracted little attention since its description, outside of reviews. It is usually considered a dubious name of either coelurosaurian\coelurid affinities (if the source predates the acceptance of Coelurosauria as a wastebasket taxon as traditionally used), or uncertain theropod affinities (if published after this). The most recent review classifies it as Tetanurae incertae sedis and dubious.[3]

Paleobiology

As a small theropod, Sinocoelurus would have been an agile, bipedal carnivore.

Miscellany

Due to romanization variations, the location may be given as Kuangyuan, Szechuan Basin.

gollark: It might actually be useful to have some kind of neural network file format detector for bad formats without clear headers. Or to help recover damaged files.
gollark: Can't wait for the `file` command to take several seconds of heavy GPU load.
gollark: You would still want to have information about the geese though.
gollark: I think a useful component of AGI would be being able to efficiently offload subtasks to specialised algorithms instead of just doing them inefficiently in neural networks, but I have no idea if this is very practical or anyone's doing it.
gollark: There are tons of non-learning algorithms which are good for logical reasoning. The fuzzier stuff which humans do easily seems to be what's harder to implement.
