Lufengosaurus juvenile

[Jocelyn Falconnet <j.falconnet@gmail.com>]

Gentlewomen and gentlemen, it seems Jerry overlooked this paper (I don't 
know how that is even possible !):

Sekiya, T. & Dong, A., 2010. A new juvenile specimen of Lufengosaurus 
huenei Young, 1941 (Dinosauria: Prosauropoda) from the Lower Jurassic 
Lower Lufeng Formation of Yunnan, Southwest China. Acta Geologica Sinica 
- English Edition, 84(1), 11-21.

A skull and a series of associated cervical vertebrae (ZLJ0112) 
discovered from the Lower Lufeng Formation (Lower Jurassic) are 
determined as a juvenile specimen of Lufengosaurus huenei Young 1941 
based on amended autapomorphies. Differences between ZLJ0112 and the 
holotype (sub-adult specimen) are considered as ontogenetic 
characteristic changes of L. huenei. Since some of these differences are 
present in other prosauropod dinosaurs (i.e., forms of the maxillary 
vascular foramen are irregular; the frontal contribution to the dorsal 
margin of the orbit is substantial; the frontal contribution to the 
supratemporal fossa is absent; the supratemporal fenestra is visible in 
lateral view; the supraoccipital inclined at 75 degrees; the 
parasphenoid rostrum lies level with the occipital condyle; the 
retroarticular process is short; the axial postzygapophysis project 
caudally beyond the end of the centrum) they may be common ontogenetic 
changes in prosauropod dinosaurs.
