The original Jurassic Park (and perhaps Lost World) were really good about obscuring the feet of dinosaurs in full-body shots of them standing relatively in one place, like in all of the gifs above. It was to help mask the fact that feet were the most difficult aspect of a cgi model to blend into the background plate, so that would of course make it hard to "anchor" the model into the world. It's not a problem with fast-moving dinosaurs
I wondered if they were still doing the same trick 20+ years later.
Looks like a probable "yes". Look at the direction of Pratt's shadow compared to those of the raptors. The raptor shadows were intentionally positioned to obscure their feet.
