Amber

The latest amber time capsule discovery comes from Oregon State University researchers who have identified a completely new, previously unknown genus and species of flower dating back 100 million years to the mid-Cretaceous period.

Scientists have successfully extracted DNA from insects trapped in amber – but any creatures you might revive from this would hail from the not-so-distant past of 2014. The study aims to work backwards to find the limits of DNA preservation.

The oldest known animal sperm sample has been discovered, dating back 100 million years. Dozens of ostracods were found in a piece of amber with their “soft parts” out, and their giant sperm measuring around a third of the animals’ body length.

Amber has offered us all kinds of fascinating insights about long-gone creatures that once inhabited the Earth. Joining them is a rare 99-million-year-old fossil that shows an enigmatic “hell ant” clamping down on its cockroach-like prey.

Most fossils are just bones, but occasionally striking specimens turn up bearing skin or feathers, encased in gemstones, and even preserving traces of DNA against all odds. Here's a look at some of the most incredible fossil finds of recent years.

Found preserved in 30-million-year-old amber, the "mold pig" is so different from anything else that it’s been placed in a new genus all of its own.

Amber can be a veritable treasure trove of ancient animals and insects, but it most commonly captures creatures that lived in forests – understandable, given the stuff starts life as tree sap. But now researchers have found a piece of amber bearing a strange mix of land and sea-dwelling creatures.

Scientist now have to reevaluate what they know – or thought they knew – about the evolution of millipedes due to a tiny, 8.2-mm member of the order Callipodida who got its many feet stuck in some tree resin, which turned up in Myanmar, 99 million years later, as a golden lump of amber.

​We've all heard about ancient insects getting preserved in amber (fossilized tree resin), with similarly-preserved items including dinosaur feathers, mammalian red blood cells and a bizarre spider. Now, for the first time, scientists have found an amber-encased prehistoric snake.

Scientists have discovered a brand new species of spider, with a feature that’s not normally seen in the creatures – a tail. If that’s making your skin crawl, take solace in the fact that the new arachnid, dubbed Chimerarachne, lived 100 million years ago and its remains were found trapped in amber.

Scientists have long suspected that ticks feasted on the blood of dinosaurs. Preserved in a 99 million-year-old chunk of amber lies a hard tick grasping the feather of a dinosaur, suggesting that the parasitic insects did indeed harbor a penchant for prehistoric plasma. ​

​There’s only so much palaeontologists can learn about prehistoric animals from fossilized bones, so on rare occasions when ancient soft tissues turn up, it’s worth taking note. Now a section of a dinosaur’s tail, complete with feathers, has been found trapped in a piece of amber.
