Dinosaurs were reconstructed based of modern reptiles, so dinosaurs have bony lizard faces because they are based on crocodiles and similar reptiles. If you want to reconstruct a mammal from the bones you surely have to consider the fact that modern mammals have different chubbier features
They should be using birds not crocodiles but the OP is correct, there have been advances in reconstruction techniques as well as new fossil finds that show previous attempts were generally poor.
That’s part of the process. As we find out more fossils and new evidence, we understand a bit better how these animals worked and looked like.
This is not the link I was looking for but it also shows some revisions we did throughout the years:
