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.
"In the end, it was not guns or bombs that defeated the aliens, but that humblest of all God's creatures... the Tyrannosaurus rex."
"Try to imagine yourself in the Late Quaternary. You get your first look at this six-foot Psittacosaurus as you enter a city. You stay still, because you think that maybe its visual acuity is based on movement. Maybe it's not all that bright. But no... not Homo sapiens. You stare at it, and it stares right back at you. And that's when it starts shooting you with this... THE GUN!" - Dr. Mongoliensis
