I learned that the chances of finding a cave painting of ancient men fighting a plesiosaur revived by a meteor, and then having the exact same thing happen again in the same place literally minutes later, is not zero as I had previously assumed.
All things have a chance greater than zero of happening, but your observation is astute. I haven't seen this movie yet, though I certainly hope that upon experiencing this inconceivable occurrence, the cracker or crackers say something like "well, if that don't beat all" or "what are the odds?"
No, they don't even mention the high improbability of a meteor hitting the same place twice, or the highly improbable timing of it. But you can't blame them, by the time they figure out it's a plesiosaur it's near the end of the movie and 6 months later. By the way, did I miss the "six months later" caption? I don't remember seeing one and when they talk about the meteor being six months ago I was surprised.
I learned that a meteor can heat up an entire lake, for several months, even though the energy required should have vaporized it before it landed, must be a very very special meteor....
