It came 24 hours after an image of the battle-scarred skull of Richard III was released for the first time. Scientists also uncovered the grave site.
The way they found the skeleton suggested the king had been tied when he was buried. There has been extensive damage to the bones, scientists say.
The skeleton had an "unusually slender, almost feminine build for a man" and was aged between the late 20s and early 30s. Richard died aged 32.
Without any "spinal abnormality", the skeleton would have been 5’ 8” high, which was above average height for a medieval man, scientists say.
A total of 10 wounds have been discovered made to the skeleton, including eight on the skull. The injuries suggest the king may have lost his helmet during the battle which saw him deposed by Henry VII.

The skeleton was uncovered last autumn amid the historic foundations of a Franciscan Friary in Leicester, beneath a council car park which is overlooked by Leicester Cathedral.
They will be reinterred early next year at the cathedral, with a visitor centre to be created nearby, which will tell the king's story.

Teams of experts carried out radio carbon dating, DNA tests and CAT scans and compared notes with experts in weapons and trauma, lifestyle and diet before announcing their findings today.
They have disclosed that the skull appears to have suffered a severe blow.
The body was identified just weeks into a project which began when experts identified the car park as the most likely historical location of the church of Grey Friars, where the King was said to have been buried after his defeat in the Battle of Bosworth in 1485.
The archaeologists initially described the dig as a "long shot" but uncovered the foundations of a church along with two bodies, one of which would prove to be the King.
As Henry VII's troops dragged the corpse into Leicester its head is said to have struck a stone and broken open.
The remains were dug up last September and Leicester University said there was “strong evidence” that it was Richard III.

The skeleton is not believed to have been buried in either a shroud or a coffin, which although unusual for the time, tallies with historical accounts that suggest he was "irreverently buried" by Henry's forces.
Richard III, depicted by William Shakespeare as a tyrant who murdered two princes in the Tower of London, was killed at the Battle of Bosworth, bringing to an end the two-year dynastic struggle known as the War of the Roses and triggering the reign of the House of Tudor.
It has been claimed the discovery of Richard's body will lead to a re-examination of his reign and may go some way to rebalancing the largely negative portrayal offered by Shakespeare.
