The problem - as I see it - is that objects like the Tan-Tan figure and the Berekhat Ram are portrayed as "exceptional" whereas they are only exceptionally mediocre and with this insight a quick scan of most site material reveals that the practice was widespread and consistent throughout pre-history.
We _can_ build on and learn from the substantial research by Boucher de Perthes in the 1800's later Leakey, Walther Matthes, more recently Jan Evert Musch, Max Herder and many others (some previously mentioned in this thread) in this field. The profile of animal types will vary depending on site location, use, etc.
Charlie, on your own site have you tried sorting them into animal types to determine the ratios? I'd be interested in what it might reveal about the activity there. You will undoubtedly have many face images too - often self portraits.
I haven't performed any formal statistical analyses, but, I can say roughly, that bird figures are most dominant:
