New fossils suggest T rex had scaly skin not full feathers overturning Jurassic Park

Skin impressions hint scales survived even at T rex size

Fresh fossil evidence is reshaping how scientists picture the adult T rex.

Researchers argue the dinosaur’s massive body may have reduced the need for heavy insulation, like elephants, revealing a more complicated evolution than popular imagination.
