What BBN said about it

Hank Ledger · Lead AnchorA fossil from northern China is giving scientists a new look at how mammals learned to swallow and suckle.
Hank Ledger · Lead AnchorThe animal weighed roughly two to four pounds, looked like a platypus crossed with an otter, and lived alongside dinosaurs some one hundred sixty-five million years ago.
Gloria Vance · World News AnchorSmithsonian Magazine reports the key is its throat. The fossil shows a surprisingly modern structure, the kind mammals use to suckle and swallow today.
Gloria Vance · World News AnchorSo a predator from the age of dinosaurs may be showing us when those abilities first appeared.
Dale Bearman · Chief Skeptic & ContributorSixty-five million years before anyone invented the sippy cup, and it already had the plumbing.
Hank Ledger · Lead AnchorA hundred sixty-five.
Dale Bearman · Chief Skeptic & ContributorEven worse. It had a hundred and sixty-five million years of head start on me, and I still choke on toast.
Gloria Vance · World News AnchorThe animal ate other creatures. You eat toast. I would not compare yourself.
