Creswell Crags Ochre Horse Rib Bone Carving Decipherment as Astronomy Update 2.0

This posting is Update 2.0 to my previously posted original decipherment on this topic as also to Update 1 of the Creswell Crags "Ochre Horse" rib bone carving decipherment.

This update provides an image of the details of the rib bone, all except for the Winter stars on the top left of the rib bone, which are already included in the previous posting, and shows that large darkened spots on the rib bone are to some degree intentional carved "placements" marking stars of the heavens, e.g. stars of Ursa Major, but also other stars, some prominent, some not so prominent, and also some that are uncertain, but in general they can be said to confirm that the decipherment is correct.

Update 3.0 will follow at some time in the future with a text explanation of various matters in detail.

The engraved bone, now popularly called the "Robin Hood Cave Horse" after the cave in which it was discovered in 1876, is dated by the archaeologists to the Ice Age ca. 12500 years ago. It is the oldest artifact (British artefact) of this kind ever found in northern Europe and, as a stroke of luck for those interested, is currently on display at the British Museum until May 26, 2013 in the British Museum exhibition: Ice Age Art: Arrival of the Modern Mind.
See the reviews at:

• “Not even Leonardo surpassed this” -- The Guardian
• “I can’t remember the last time I saw a show with so many rare and beautiful objects” -- The Telegraph
• “The exhibition everyone should see” -- The Times
• “Astonishing” -- Metro

For today, only this updated decipherment, no text.
In the course of time I will reveal how I arrived at this solution. Enjoy.

"Creswell Crags. The Ochre Horse. This original fragment of a rib bone contains the oldest known carving of its type in Britain. The horse was carved approximately 12,500 years ago and was on temporary display at the small museum at Creswell Crags to November 2009 (although a replica of the ochre horse is always on display). It was found on the 29th June in 1876 at the back of the western chamber in the 'Robin Hood Cave' in Creswell Crags. Sieveking 855, British Museum.
