Well they didn't show a good layout of the park (there was a map, but it doesn't help). It is really huge though, so you may just wanna get creative. Make sure you have a type of mountain or plateau for the elephants and mammoth.
Ornithimimus (a herd) - grassland with pond
T-rex (one male, one female) - grass
Triceratops - grassland with pond
elasmotherium (wooly rhino) - grassland
mammoth - savannah
Titanosaurs - grassland
some feathered "birdosaur" that didn't actually have an exhibit
smilodon (one male, one female) - grassland
phorusrhacos (that giant flightless terror bird) - grassland
giant millipede, scorpion, and dragonfly - rainforest type area
Deinosuchus - grass and beach on lake
troodon (they never gave it an exhibit either, just captured it) beachside forest
Oh, and don't forget about the nile crocs and african elephants. The crocs had a pond and the elephants shared a savannah exhibit with the mammoth. There was also a cheetah, probably in savannah.
