Here are all the creatures that appear in the Jurassic World: Dominion Trailer (in order of appearance)!
Parasaurolophus
The Paras show up a lot in the trailer, interestingly they have a new bulkier look.
Apatosaurus
Apparently Littlefoot wanted to be a lumberjack when he grew up.
Velociraptor
Obviously, Blue is back, but surprisingly she has a baby (who according to leaked toy images, is named Beta). The VR game Jurassic World: Aftermath hinted that Blue was potentially capable of reproducing through parthenogenesis, due to having varanid DNA.
Mosasaurus
The Mosasaurus seems to be taking after the ship destroying sea monsters of legend, (Insert overused "We're going to need a bigger boat" reference here).
Tyrannosaurus rex
Obviously we can't have Jurassic World without the queen!
Therizinosaurus
Don't worry Claire, it's a herbivore (hopefully the film remembers that)
Atrociraptor
Described as the "more savage and brutal" cousins of the Velociraptors, Owen definitely won't be training these guys.
Pyroraptor
The first fully feathered dromaeosaur in the franchise, it even has scientifically accurate wings!
Unknown Species
A weird addition to the trailer, they appear to be some type of insect. Not sure whether these are normal modern day insects or some type of prehistoric species.
Allosaurus & Carnotaurus
Two large carnivores for the price of one!
Quetzalcoatlus
Continuing the trend of pterosaurs hating aircrafts.
Pteranodon
They still hate aircrafts as well.
Nasutoceratops
Cars vs stampeding Dinosaurs. The Dinosaurs win.
Dilophosaurus
The "Spitter" finally returns to the movies, and it's fully grown too!
Giganotosaurus
Our new "Big Bad" is here!
I screwed up a little with the spacing on the Pteranodon section, but oh well...
Am I the only one get even more indo vibes from Giga, literally is an indo with a thinner snout.
expecting the worst, sets you up for thr worst
I've heard some suggestions that the "Unknown species" may be a large flock of birds, although the way they're flying seems really reminiscent of insect swarms. I guess we'll have to wait to see what they actually are...
Considering that the Indominus rex was made using Giganotosaurus DNA, it makes sense that they have some similarities. They may have even designed it that way to indicate that a large amount of Giga DNA was used in the Indominus rex's creation.
Okay, after watching these videos, the "unknown species" could actually be birds.

Geese can hurt people in flocks….
just sayin

In flocks? One goose is scary and dangerous enough on its own...
Okay never mind, it seems like the "unknown species" are some type of large bug. In the shot towards the end of the trailer where the Giga appears, you can actually see what looks like a large bug that's on fire and is flapping it's wings. they could potentially be the large bug that briefly appeared in the Prologue which was seen flying around the legs of a Dreadnoughtus.
