Insects evolved at least 420 million years ago, and their rise to become the most diverse and ecologically important class of terrestrial animals is a story beautifully recorded in the fossil record. The AMNH never had a researcher of fossil insects prior to 1986, but the collections have grown enormously since David Grimaldi joined the staff (Evolution of the Insects). Indeed, the collection of amber fossils is arguably the mo

Scientists Find Oldest Amber Arthropods on Record

Preserved for 230 million years in droplets of amber just millimeters long, two newly named species of mites and a fly have set a record. They are the oldest arthropods – invertebrate animals that include insects, arachnids, and crustaceans – ever found in amber, the name typically given to globules of fossilized resin. The results, published by an international team of researchers in theProceedings of the National Academy of Sciencestoday, pave the way for a better evolutionary understanding of the most diverse group of organisms in the world.

“Amber is an extremely valuable tool for paleontologists because it preserves specimens with microscopic fidelity, allowing uniquely accurate estimates of the amount of evolutionary change over millions of years,” said corresponding author David Grimaldi, a curator in the Museum’s Division of Invertebrate Zoology and a world authority on amber and fossil arthropods.

Even though arthropods are more than 400 million years old, until now, the oldest record of the animals in amber only dates to about 130 million years. The newly discovered specimens are about 100 million years older, the first amber arthropods ever found from the Triassic Period.
