AMBER . Frozen in amber, many fossils around the world testify to the history of our planet. The amber chips in question here were collected in the 1950s by an entomologist named Milton Sanderson. They come from a deposit in the Dominican Republic and are dated 20 million years.

A long and painstaking

Many fossils discovered at the time were written about in the journal Science in 1960, but many treasures were still waiting scientists. They have undertaken since 2010 a new examination of these pieces of amber that are now marked and obscured by oxidation. To see through, they should overlap and polish again. A painstaking but successful: many fossils of flies, bees, arthropods, plants and even a bit of mammal were found.
