I watched a PBS special about this theory. and they demonstrated how an impact crater wouldn't be found. Many times comets themselves are pieces of rock, gas, and ice..instead of one large whole piece of rock. So if one were to enter the atmosphere, it wouldn't be like an asteroid that would leave a large crater. instead it would be like tossing pea gravel onto sand, but obviously on a much larger scale. Thus leaving many shallow craters that could easily fill with sediment over time.

I know Jupiter is H-U-G-E but it's still somewhat frightening that it can be hit by something big enough to leave a dent that size and we don't realize it's coming till after the fact.
@Qev: Yup, That Guy below mentioned JPL's confirmation as well. The Austrailian gets no props from them, figures.
Funny thing, exactly 15 years ago Shoemaker-Levy 9 smacked Jupiter with it's infamous "string-of-pearls" between the 16th and the 22nd of July.

If Jupiter is primarily a gaseous plant, how would this form and remain? Wouldn't it simply dissipate within a few days.
