If you look at the output of the gyro using a scope or spectrum analyzer, you'll notice some significant fourier noise products above your 75Hz Nyquist frequency. This noise is aliased back into your 75Hz bandwidth, and certainly isn't Gaussian in nature. You might want to up your sampling frequency to the ~1600Hz sweet spot.
