Thanks, Barbarian (BTW, do you prefer to be addressed as “The Barbarian”, or is just “Barbarian” acceptable?).
Over most of the past decade this dino-soft-tissue has been one of the favorite, and hardest to give good answer to, claims thrown against deep-time by the creationist community. It will be interesting to see what counter-moves Schweitzer’s new (as of 18 months ago) article elicits from the creationist community (Enyart being a prime example of someone who relished the dino soft-tissue argument.)
I see this dino soft-tissue as a prime example of the way science plays out sometimes – the researchers huddle over their experiments and suddenly jerk their heads up with egg on their faces (speaking figuratively), since they just found something that just didn’t fit in with expectations at all. Had Schweitzer taken the advice of her creationist nay-sayers, she would have declared that all dinosaur dating to date must have been critically in error, and must be rejected en-masse. But instead, she was a scientist is the truest sense, and recognized that nature had just provided an opportunity for gaining a deeper, and unexpected, understanding of how biological molecular processes can work. A few years of hard work, and now we have new insights into some important aspects of how molecular structures can be preserved. For the young-earth crowd, another gap where they can find their YEC version of God has just been eliminated.
Just for kicks, here is the link to Schweitzer’s article in all its gory detail:
