[meteorite-list] The age of Mifflin. ?470 million years? Really?

[Joe Kerchner]

Hello all,
   It the 470 million year age for the Mifflin meteorite correct? if so, isn't that very young for a meteorite? I have been under the impression that the average age of a meteorite was 4.57 Billion years old I know that's an average, but isn't 470 million way too young? Theres no way that it is so young, is there?
  I read that in a couple articles online today. below is a link to one of them.
