New findings as to Yuananensis (juvenile, in side elevation)

["Zheng Sun" <ssun66@china.com>]

 

 

Hi all,

 

        This is Zheng Sun, one of finders of Keichousaurus regarding new structures as attached pictures.

Now in the origin area of Keichousaurus, we found a juvenile yuananensis with special structure, a completed clear body, fossilized in positive and negative molds (limestone slab), maybe it is a new finding-point compared with previous study in Keichousaurus.

 

        This yuananensis 's length is just 60 mm, the head, the neck, and the tail are similarly constructed as the named species, but please focus on its dorsal aspect, you will find a row of higher similar spinous thorns.

 

        If you have interest in vertebrate palaeontology and palaeoanthropology, welcome to cooperate in study, attached 2 pictures as below.
