What's supposed to be a "dinosaur encounter"? Just any scene that has a dinosaur in it? If so, that's a really strange way to word it. Anyways, the list is mostly fine, but I would not put these in a Top 10 list of best dinosaur scenes of the franchise:
The Brachiosaurus Left Behind from Jurassic Park: Fallen Kingdom - I like the intention and the visuals of that scene, but from a standalone movie perspective, it was extremely unearned, and having the Brachiosaurus mimic its iconic pose as it died was eye-rolling.
The Compsognathus Attack from The Lost World: Jurassic Park - It's a fine scene on its own (if a little over-the-top), but I would not place it in a list of best scenes of the franchise.
Two T-Rexes Attack the Trailer from The Lost World: Jurassic Park - Again, a fine scene, but it always had two big problems for me: one, is that it's too much like the T. rex breakout from the first movie (so having both on the same list feels a little redundant); and two, the two T. rex are completely offscreen for most of that scene.
The Spinosaurus Vs. the T-Rex from Jurassic Park III - Again, fine scene on its own (and unique for its time), but, much like the Brachiosaurus scene from FK, it was unearned from the perspective of a standalone movie, and it's over and done way too quickly, considering what it is.
I would replace the "Two T-rexes Attack the Trailer" with the "game trail" scene, the "Compsognathus Attack" with the "Raptors in the long grass", the "Brachiosaurus Left Behind" with the "T. rex/Mosasaurus attack the mercenaries" from the FK prologue, and the "Spinosaurus vs. T. rex" with the Spinosaurus duel at the lake from the climax of JP III. I would also include the T. rex rescue at the rotunda somewhere, probably replacing either the Dilophosaurus scene or the climax from JW.
