Can anyone determine whether the destruction pictured is real?

In a recent article about the destruction of monuments and cultural heritage sites by representatives of the Islamic State (“Islamic State Destroys More Artifacts in Iraq and Syria”, The New York Times, July 4, 2015), reporters Rick Gladstone and Maher Samaan note that there is some speculation that the photographs posted by Islamist media outlets of destroyed statues from Palmyra, Syria seized from a smuggler may be of fake statue remains and that the sculptures were smuggled by the Islamic State fighters themselves. Is the resolution of these photos good enough for conservators who are experts in stone to determine from the edges and breaks whether the remains in the photos are old and of the type of stone they should be if the real thing?
