Fossils of various kinds are found around the world, but few specimens are as well preserved as those whose end came via a blob of tree resin. Researchers have found a number of scientific treasures locked away in amber, with many dating back millions of years. Those discoveries include the tiniest known dinosaur, the earliest evidence of insect-to-flower pollination, and the oldest-known mammalian blood cells. Scientists also found an insect that bears a striking resemblance to E.T.
