Don't get me wrong, I like the angle this episode takes, it is filled with information that gives us a good insight on many aspect of the T-Rex that were not really discussed or put together before. It does present this beautiful animal as a complex living thing in a complex world but there are so many parts that are hard to watch if you are looking at it from a serious point of view.
Besides the giggling like teenagers while crushing bones with a press (while saying that this is the bite of the T-Rex (no it's not, it's a very slow press), there are this quote that really got to me. They are trying to figure out what kind of noise the T-Rex would do. They use a crocodile calling sound and lower it by 2 octaves. Ok, I get it, we don't know really, we probably won't know until we have some kind of tech that could be rebuilding the sound precisely with the measurements of the skull, yes. But this guy saying: "This could be the first time for 66 million years that this sound has been heard on earth" is the equivalent of an alien eating sand and calling it ice cream. No, Sir. This is not a sound that wasn't played for 66 million years, unless you had a recording studio 66 million years ago that played with the sound of a crocodile and lowered it by 2 octaves. I might be nit picking here though. Maybe the T-Rex sounds exactly like a deep voiced crocodile....
