    How do we know its body temperature was 97 degrees, and simply not the environment was 97 degrees?

      If it was environmental then you'd expect it to fluctuate over time, but they also checked it against an animal they knew to be cold blooded, if it was environmental you'd expect them to be the same, but that animal was calculated by the same method to be colder.
