Based on the information of the retro-engineering project, scientists won’t be able to bring back dinosaurs such as Brachiosaurus, Triceratops, Tyrannosaurus Rex, or Stegosaurus. Instead, they can recreate dinosaurs from the Maniraptora family, which were feathered dinosaurs such as Archaeopteryx, Raptors, Ostrich dinosaurs like Gallimimus and Oviraptor, and Therizinosaurus. Once they complete the project and work the bugs out, we will be seeing “modern” versions of these animals. I will keep this in mind in the future as I brainstorm.

I just want my own T-Rex. Is that too much to ask?
Why these particular dinosaurs? What is it about them that makes them the ones we might be able to replicate?
Probably because they are very bird-like.
I was thinking that maybe they were “newer” evolutionarily speaking, closer to modern times, and therefore easier to extrapolate to.
