Description
Jingangkou Formation:

Species that were omitted:
01-Chingkankousaurus: an indeterminate tyrannosauroid know from a broken scapula, since the material and classification are not great I decided to no add this taxon in the chart.
02-Some sort of Ankylosaur: an ankylosaur is know from the formation and was classified as Pinacosaurus grangeri; I do not believe in such classification and since I did not found the paper/publication it was mentioned I couldn't even try to scale and add it in here.

Xingezhuang Formation:

Species that were omitted:
01-Micropachycephalosaurus: the taxon has no stable phylogenetic position, so since I had no reference I'm not putting it in.
02-Therezinosaurid: one ungual referred at the Theropod Databse, it is an ungual so not scaling.

for Shantungosaurus skeleton.
Sinoceratops skeleton is a composite of skull and Albertaceratops body; I don't know who made this can someone tell me?
