>>212722069 (OP)There was a reaction against so called "shrink-wrapped" dinosaurs, which was a trend in the 90s- 2000s.
Greg Paul started it all, and probably took it too far. His book Predatory Dinosaurs of the World is the reason Jurassic Park called them Velociraptors instead if Deinonychus. Velociraptor is a Mongolian genus, but Paul lumped the larger American Deinonychus in with it as a species of Velociraptor. No one else ever recognised this categorisation, but his book sold a lot of copies.
If you look up his illustrations, you will see who everyone was copying for over 2 decades. He is quite a brilliant anatomist, but in addition to his anorexic reconstructions, he got dinosaur arms all wrong, and everyone just followed his lead, then the pendulum swung in the opposite direction.
In reality reptiles have very little subcutaneous body fat. That is primarily a mammalian trait.
