Theories in Jurassic Park/World Community

"Welcome. To Jurassic Park." - John Hammond
One of my many theories is that the Scorpios Rex made a 3rd one which stayed on the island until Biosyn went there and saw it, so they took it and decided that it was to dangerous and put it on Rebirth Island. Highly unlikely but you never know
a theory is that rexy is 34 but shes in captivity so she isnt dead
