A remarkably well-preserved fossil of a dinosaur has been analysed by scientists writing in the journal Proceedings of the Royal Society B.
They describe how the fossil's soft tissues were spared from decay by fine sediments that formed a mineral cast.
Tests have shown that the fossil still holds cell-like structures - but their constituent proteins have decayed.
The team says the cellular structure of the dinosaur's skin was similar to that of dinosaurs' modern-day descendants.
