Headscratchers / Jurassic World Alive

• While perfectly understandable that non-hybrid creatures would be present in the wild (Considering the game takes place after Jurassic World: Fallen Kingdom), the description of some hybrid creatures imply that Hybrids also roam the wild ingame. How are they able to be present in the wild? Interspecies breeding? However, the description of the Pterovexus may imply that Hybrids escape from the labs they are created in.
• Why is Panthera blytheae considered a Legendary creature and Dracovenator and Ceratosaurus considered Uniques despite just being regular animals? Rexy is understandable since she went head-to-head with the I. rex, another Legendary, but nothing about these animals in real life is any more spectacular than your average Monolophosaurus or Lythronax. Even Parasaurolophus lux gets a pass due to its bioluminescence, so what's up with these guys for them to be ranked alongside the powerhouses cooked up in the DPG's labs?
