Mary Anning was a pioneering fossil hunter from Lyme Regis, Dorset, whose discoveries along the Jurassic Coast helped establish the foundations of modern paleontology. Born in 1799, she uncovered some of the most spectacular Jurassic marine reptiles ever found—including the first complete ichthyosaur skeleton, the first recognized plesiosaur, and the first British pterosaur remains.
Despite living in an era when women were excluded from scientific institutions, Anning became a respected expert among leading geologists of the 19th century. Today she is celebrated as one of the most important early fossil collectors and an enduring symbol of scientific perseverance.
From her childhood on the fossil-rich beaches of Lyme Regis to her death at 47, Anning’s story is one of relentless curiosity and skill. The cliffs she worked are now part of the UNESCO Jurassic Coast World Heritage Site, and her legacy continues to inspire new generations of scientists and fossil enthusiasts.

What Did Mary Anning Discover?
The First Complete Ichthyosaur Skeleton
When Mary Anning was about 12 years old, she uncovered a large ichthyosaur skeleton in the cliffs near Lyme Regis. This find, made around 1811, brought her wider attention and is considered one of her earliest major discoveries. The ichthyosaur was a marine reptile that lived during the Jurassic period, and Anning’s specimen was one of the first to be studied by scientists, significantly advancing knowledge of extinct sea creatures.

The First Complete Plesiosaur
In 1823, Anning found the first complete plesiosaur skeleton. The animal looked so unusual—with a long neck, small head, and large flippers—that some scientists initially suspected it was a fake. The find sparked debate and later helped confirm the reality of extinct reptile groups. Natural History Museum: Mary Anning
The First British Pterosaur
In 1828, Anning identified the first pterosaur remains found in Britain, later associated with the species Dimorphodon macronyx. This discovery proved that flying reptiles had lived in the region during the Jurassic, expanding the known diversity of prehistoric life. Lyme Regis Museum: Mary Anning Collection
Anning’s discoveries provided some of the first clear evidence that species could go extinct—a radical idea in the early 1800s. Her fossils helped scientists reconstruct ancient ecosystems and laid the groundwork for the theory of evolution.
How Did Mary Anning Die?
Mary Anning died on 9 March 1847 in Lyme Regis. Historical records, including local parish documents and modern analysis, report the cause as breast cancer. She was 47 years old at the time of her death. BBC Bitesize: Who was Mary Anning?
In her later life, Anning continued to collect and sell fossils despite financial difficulties. She maintained correspondence with prominent scientists and was eventually granted an annuity by the British Association for the Advancement of Science, which helped ease her money troubles. Her death in Lyme Regis marked the end of a life dedicated to uncovering the prehistoric past.
While breast cancer is widely accepted as the cause of death, some historical accounts mention other ailments. The exact details of her illness are not fully documented, and no autopsy records are known to exist.
What Were Mary Anning’s Family and Early Life?
Mary Anning was born on 21 May 1799 in Lyme Regis to Richard Anning, a cabinetmaker, and Mary “Molly” Anning. Her father taught her how to search for fossils along the local cliffs, a skill that would define her life. National Geographic Kids: Mary Anning Facts
Mary had at least one brother, Joseph, who also collected fossils. Mary, Joseph, and their mother continued selling fossils to make ends meet, often barely scraping by.
Childhood Fossil Hunting
Anning began exploring the fossil-rich cliffs around Lyme Regis as a young child. The area’s Jurassic Coast geology preserved an abundance of marine reptiles, fish, and invertebrates. Her earliest finds, sold to tourists, helped support the family after her father’s death.
The cliffs of Lyme Regis are part of the UNESCO Jurassic Coast World Heritage Site. They are famous for yielding exceptionally preserved fossils from the Early Jurassic period, which Anning expertly extracted.
