Old Billy was the oldest horse that ever lived, and this is his skull – he lived to be 62! He was born in 1760, and worked pulling barges along the river and lifting goods out of boats for the Mersey and Irwell Navigation Company in Warrington.
After working for many years, he lived in fields at the side of the River Mersey, where he was a local celebrity for his old age. He had his picture painted by the artist Charles Towne in 1822, only a few months before he died, and a picture book was made about him in 2023, 200 years after his death.
The front teeth can help tell the age of a horse, and the more they meet on a slope, the older the horse is likely to be.
