The Woman Who Found the First Monster
September 5, 2026 · by White Nights
Mary Anning was twelve years old when she helped dig a complete skull out of the cliffs at Lyme Regis, and the creature it belonged to had never been seen before. It was 1811. The bones were nearly two hundred million years old. The animal had eyes the size of dinner plates and a jaw full of teeth, and nobody had a word for it yet.
Her brother had found the skull first. Mary spent the next several months excavating the rest of the skeleton from the rock — carefully, methodically, in a cliff that was actively crumbling around her. The finished specimen was about five metres long. She was a child working in a shawl on a Dorset beach, and she had just introduced the world to the ichthyosaur.
Over the following decades she would find plesiosaurs, pterosaurs, and hundreds of specimens that helped reshape what the scientific community understood about prehistoric life and extinction. She identified coprolites — fossilised faeces — as exactly that, and helped geologists understand the food chains of ancient seas. She taught herself geology, anatomy, and French so she could read the papers being written about her own discoveries. The papers were being written by men who had bought the fossils from her.
She was rarely cited. She was not admitted to the Geological Society of London, which did not accept women. When the society finally acknowledged her, it was with an honorary membership, awarded a year before she died. She had been selling fossils her entire adult life to pay rent.
The ammonite is one of her signatures — a spiral shell common in Jurassic rock, beautiful in cross-section, evidence of creatures that vanished long before the dinosaurs. We put it on a tee because it's a good shape, and because Mary Anning deserves to be on more things.
