TheDinosaurDave, 
This weeks #Lego #FossilFriday is #Huayangosaurus
In 1979-80, partial remains of twelve stegosaurian individuals were found near Zigong China.
In 1982, they were named and described by Dong Zhiming, Tang Zilu and Zhou Shiwu as Huayangosaurus taibaii.
Some replicas show it with a Kentrosaurus style shoulder spike, others do not. I could only find an image of one without.
Original Lego model by Kongzilla, modified by myself to represent a new species.
