A skeleton of the biggest fish ever to inhabit the world's oceans has been put on display in Glasgow.
The bones of the fish have been slowly restored
The fish, a leedsichthys problematicus - or Big Meg as the fossil has been nicknamed - measures more than 15 metres in length.
Experts believe it would have swum the Middle Jurassic seas 155 million years ago, at a time when dinosaurs dominated the land.
With more than 900 bones collected, Big Meg is said to be the most complete specimen in any collection in the world.
The skeleton was sold to the Hunterian Museum, now part of Glasgow University, in 1915 by the Peterborough fossil collector Alfred Leeds, whose wife Mary Ferrier Fergusson came from Glasgow.
Jeff Liston, vertebrate researcher at the Hunterian Museum, said work to repair the specimen only began five years ago.
But he said after much reconstruction, Big Meg looks a little more like a fish with many large bones from the her skull, as well as some bones from the fins.
Mr Liston said: "The dorsal fin alone is over a metre long. The really large marine animals of today like whale sharks or basking sharks feed on plankton, which is what we believe Meg did.
Part of a skull bone was found encased in clay
"There are no teeth on this fish, but it had huge amounts of gill rakers which it would use to filter plankton and small prey from the water."
The fossilised fish has now been put on display at the museum.
It is also due to be the subject of a forthcoming television programme in the BBC's next Walking with Dinosaurs series.
