Earlier quoted context omitted.
It sounds like you didn't read the comment I was actually replying to. It links to this article, different from OP, that does not mention what you claim it mentions: https://www.haaretz.com/archaeology/MAGAZINE-2-000-year-old-...
They didn't miss the article you were referring to, they were just assuming you had read the topic article as well. The article your read refers to 2,000 year old sculptures because it was written years before the research that added 6,000 years, not because they're different camels.
Unfortunately it's vague whether or not the different pictures are from different time periods, different sites, or what exactly.
