Good find!
Many have talked about these possible "evolutionary jumps,"(including the 2012 brigade!)-
Its a shame the finds have been dated to 160 million years ago,as I was thinking that if this jump had occured in a time when humans made fired
ceramics we could check the magnetic field of the earth at the time,to see if there may be a relationship between them.
Maybe there is some other way of finding this information out though.
