No frog DNA

This goes back to an old discussion if the Rex was being over used but I wanted it to return but have a new look then that got me thinking, Is there going to be dinosaurs with frog DNA or pure dinosaurs because we may have deadlier better sighted Rexes and normal Dilophosaurus but all animals might look different but the velociraptor can only change in color because in the first jurassic park, they showed a huge fossilized velociraptor so they can't be normal sized
