Who was Mary Anning?

Mary Anning was born in 1799 in Lyme Regis, a seaside town on the south coast of England known as the Jurassic Coast.

Mary’s family did not have much money, which meant she didn’t get to attend school much. Instead, she mainly taught herself to read and write.

Her dad was an amateur fossil hunter and by the time she was five or six, Mary was interested in fossil hunting too.

Today, she is remembered as one of the greatest fossil hunters ever.

Dinosaur fossils weren’t just created by their bones, you can also find fossilised dino-plops, something Mary Anning was quite the expert in…

What fossils did Mary Anning find?

Mary found most of her many fossils on the cliffs and beaches of Lyme Regis.

Between 1811 and 1813, Mary unearthed a five-metre-long skeleton. It was recognised as a marine reptile and named Ichthyosaurus.

In 1823, she discovered the fossil of a Plesiosaurus.

Her findings showed that strange creatures lived millions of years ago.

As a woman, male scientists often ignored her work and she generally wasn’t invited to scientific gatherings.

Today, she is remembered as one of the most important fossil hunters.

Why are fossils important?

Fossils can help people to understand what life on Earth was like in the past

Scientists use fossils to:

  • identify plants and animals that once lived on Earth but are now extinct

  • see how organisms have evolved over time.

  • study climate change, for example fossils of tropical plants found in cold places suggest that these places used to be warmer

  • show how land, seas, and environments have moved and changed over millions of years

To sum it up, fossils show us what organisms lived, how they adapted to their environments, and how our planet has changed over time.

Horrible Science fact

Fossils aren’t just poo — they can be footprints, leaf imprints, or bones.

The largest fossil ever discovered belongs to the Argentinosaurus. It is estimated to have been up to 35 metres long and weighed around 70,000 kilograms (that’s the same weight as about 10 African elephants).
