Description A remastered version of the previous Nanuqsaurus (adult) skeletal, done for #NanuqsaurusDay .
Multiple reconstructive choices were done based off phylogenetic placement. As Nanuqsaurus is placed basal to both Daspletosaurini and Tyrannosaurini, anatomical traits from Daspletosaurus, Teratophoenus, and Albertosaurus were used as reference and composite.
Nanuqsaurus is a late-Cretaceous Alaskan tyrannosaur known from the Prince Creek Formation. Although it is often known as a "dwarf tyrant" (which isn't a literal translaton), it is hypothised and proven that the holotype is a younger individual "We note that other Prince Creek Formation tyrannosaurid material in the UAMES collection do not support the assertion that Nanuqsaurus is a diminutive, small-bodied tyrannosaur. Rather, adult-sized teeth and isolated postcranial elements suggest an adult body size more closely comparable to other North American tyrannosaurid taxa, such as Albertosaurus sarcophagus" (Druckenmiller et al., 2021). 
More Nanuqsaurus content meant to improve my previous works will appear later. 

Scalebar based off hypothetical adult size.
Beige coloration represents unpublished material, namely teeth and quadrate. 

I explain much more in my Tumblr reconstruction guide, but fair warning that aspects of the post is low quality and will eventually be updated: bastion14.tumblr.com/post/6540…
