| Fossilized Insect in Amber |
Millions of years later, that insect may still be visible, suspended inside a golden piece of fossilised resin.
Its delicate wings, slender legs and even the finest hairs on its body can sometimes be preserved in astonishing detail.
Welcome to the remarkable world of amber fossils.
WHAT IS AMBER?

Fresh resin is sticky and can trap insects, spiders, plant fragments and other small organisms that encounter it.
Under suitable conditions, buried resin undergoes chemical changes over geological time, eventually becoming amber.
Unlike many fossils preserved in sedimentary rock, amber inclusions can retain extraordinarily fine three-dimensional details.
These tiny time capsules allow palaeontologists to examine ancient organisms in ways that are rarely possible with conventional fossils.
AN ENTIRE WORLD IN A DROP OF RESIN
Amber has preserved an astonishing diversity of prehistoric life.
Scientists have discovered ancient ants, beetles, flies, spiders, flowers, feathers and even fragments of vertebrate animals.
Some specimens capture interactions between organisms, including predators and prey or insects associated with plants.
These discoveries offer rare evidence of how ancient ecosystems functioned.
Rather than simply telling us which species existed, amber can sometimes show us how they lived together.
THE CRETACEOUS FORESTS OF MYANMAR
Some of the most scientifically significant amber fossils come from deposits in northern Myanmar, dating to approximately 99 million years ago.
These Cretaceous specimens have revealed an extraordinary diversity of insects and other organisms from a tropical forest ecosystem.
Researchers have described unusual insects, delicate flowers, feathered remains and many other remarkable inclusions.
However, Myanmar amber also raises serious ethical concerns relating to mining, conflict, provenance and the ownership of specimens.
For palaeontologists, understanding where a fossil came from and how it was obtained is an essential part of responsible scientific research.
CAN WE FIND DINOSAUR DNA IN AMBER?
It is a wonderful idea, made famous by Jurassic Park: extract ancient DNA from a blood-filled mosquito and bring dinosaurs back to life.
Unfortunately, real science is rather less accommodating.
DNA breaks down over time, and scientists have not recovered authentic dinosaur DNA from Mesozoic amber.
Amber can preserve astonishing physical details, but it does not provide a reliable way to resurrect extinct dinosaurs.
The real discoveries are fascinating enough without bringing a Tyrannosaurus rex into the modern world.
WINDOWS INTO VANISHED FORESTS
Important amber deposits have been discovered in the Baltic region, the Dominican Republic, Lebanon, Canada and many other places.
Each deposit captures a different chapter of Earth's history.
Some preserve ancient tropical forests. Others reveal ecosystems from cooler climates or much earlier geological periods.
Together, they help scientists reconstruct vanished landscapes, identify extinct species and understand the evolution of insects, plants and their ecological relationships.
FOSSIL HUNTRESS FIELD NOTE
Not every golden-coloured piece of fossil resin is amber. Copal is younger resin that has not undergone the same degree of fossilisation. Scientists examine its chemistry, geological context and physical properties to help distinguish it from amber.
The next time you see a piece of amber containing a tiny insect, remember that you are looking at more than a beautiful fossil.
You are looking at a moment in an ancient life, preserved across millions of years.
