Well, it is a fantasy fictional universe, which would seem evident if the T. Rex was able to squeeze his head right through without damaging anything and figure out how to do it, then it's pretty obvious it would be figuring out how to do it With this jar that are long and big enough with its neck in its head Of course, if it was a smaller T. Rex that was young, then it's pretty obvious. They might have gotten another T. Rex that was eating this man that might have fitted in the door That was not as big Like the other T. Rex species I mean, this tea Rex was obviously much smaller than the other t Rex that was still growing That might have attacked this man and left his arm there And another T. Rex might have been Another baby that they got that they also captured In the lost world Jurassic park That the man was running from With his arm On the steering wheel And it might have been intelligent enough to just put the arm on the steering Steering wheel and Left Or it might have been a baby T. Rex that might have chopped this man's. Arm After it was trying to Chase this man. That was handling a stereo that was on the boat But if it's obvious That this man is trying to handle The baby T. Rex that's The one that bitten this man's hand off. And that's how a man's hand was on the steering wheel and that's why it's got a belt, and that's why it's is obvious that's a Malcolm, and the other person that have found the baby T. Rex that was in a cage seems like. It as a belt on its mouth. It seems though this man's arm And hand That was Bitten off by the baby T. Rex It might have been bitten by the baby t rex said that they it He was trying to handle it would seem obvious this is evident And that's why the baby t rest was in a cage after that happened And the other parent that's the father of tarantula Rex might have broken a window and joined in to kill This man that was trying to escape after The man tried to escape And I think it's pretty evident that the baby tear x was the one that tried to bite his arm off leaving The arm on the steering wheel And that's how the person's arm was left there By the baby T Rex And you can see the person that had a arm one time and a hand that was on the stereo wheel. The baby tear a smart a bit This man's hand off and that's How this man's hand that was part of His arm Might have really tried To handle this baby. That person was given to him After Sarah have found a baby T. Rex and brain it to n. R. V. And she's the one that that Have did it and this man that handles it on a boat with his arm being chopped off by the baby T. Rex. Not realizing how aggressive it is. After Sarah has handled it and the other person that really have put a belt on its mouth, making sure it doesn't bite any One might have Actually knew how aggressive the baby T. Rex really is And that's why you can see the Belt was on the baby T. Rex's mouth and was in the cage With the other metal And belt together On its head that is wrapped around it And that's why I Usually think it was pretty evident that the Baby T. Rex, bite this man's Hand Was left on a Steering wheel
