Nanuqsaurus Through the Decades

Based on 𝕎-𝔸 𝕎𝕠𝕣𝕜𝕤𝕙𝕠𝕡's/jimmadseni challenge #DinosThroughTheDecades. Nanuqsaurus despite its fragmentary nature has had a long history of what interpretations have been accepted.
2000-2014 is based off of Fiorillo et al., 2000, in where only teeth were found and wasn't yet named until 2014. Originally it was classified as an Albertosaurine. Many interpretations such as the Walking With Dinosaurs 3D one lumped the teeth into Gorgosaurus or Albertosaurus.
2014-2020 is based off of Fiorillio & Tykoski, 2014. Fragmentary material was found and it was placed as a more derived member of Tyrannosauridae. The depiction here is based off of the trope of the Polar Bear Nanuqsaurus where it is overly feathered and depicted as a "dwarf tyrannosaurid"
2020-Present is based off of Voris et al., 2020 and Druckenmiller et al., 2021 where it is first placed basal to the Tyrannosaurini-Daspletosaurini lineage (but more derived than Teratophoneus and co) giving it the more Daspletosaurid look and, then it is upsized in the latter paper to be closer to Albertosaurines. This breaks the dwarf polar bear trope.
Other depictions can include other forms of Albertosaurine, lipless, featherless, or more feathered interpretations which can be found between each era.
