Jurassic Park is a great example - they also had excellent compositing to hide any flaws (compositing never gets mentioned in casual CGI talk but is one of the most important steps)

The dinosaurs were also animated by oldschool stop motion animators who were very, very good at their jobs. Another very underrated part of the VFX pipeline.

Doesnt matter how nice your 3D modelling and texturing are if the above two are skimped on !
