The True Killers

As a comparison possibly in real life, say it takes 8 dromeasaurus to take down a forty foot long edmontosaurus that is 20 feet tall and 4 tons, that would be saying 8 tyrannosaurus could take down an edmontosaurus that is 260 feet long and 96 feet tall and nearly a 1000 tons. It just can't happen for the T. rex. The Dromeasaurs are very smart, even low levels of problem solving smart. There is only one herbivore that a dromeasaur couldn't kill, the sauropods. And maybe a bunch of Utahraptors banded together to take down a 50 foot Sonorasaurus. It would take a while to kill, but it is like giganautosaurus vs. argentinasaurus. T. rex kills animals its size or smaller. Spino might kill a larger animal, but will proboly settle for ouranosaurus. The allosaurs take on animals much larger than themself, but they aren't very smart. The raptors were really the main threat to people in the film, especially the second. You guys don't have to agree with me, but going size wise comparing, raptors took on much larger animals compared to their own size.
