Ichthyosaurs or ‘sea dragons’ were marine reptiles that swam the oceans during the time of the dinosaurs. A fossil unearthed at Doniford Bay during the 1990s is giving new insights into the life and death of the mysterious creatures.?
This ichthyosaur was a female that was pregnant at the time of death. It's one of only three to be found with an unborn baby inside. The fossil was sold to a private collector who kept it on his living room wall. It was eventually acquired by a German museum where its scientific value came to light. Scientists at the University of Manchester who examined the specimen say it's the largest of its kind at more than three metres long.
The first skeleton of an ichthyosaur was discovered in the cliffs near Lyme Regis by the Victorian fossil hunter Mary Anning. Her discovery shook up the scientific world and provided evidence for new ideas about the history of the earth.?
Two centuries on, there's still more to learn about the prehistoric sea creatures that dominated the oceans for millions of years.
