Representational art, is art that is carved in the shape of something like an animal or human. This antler is a picture of a horse, not carved into the shape of a horse......
So, although not know at the time, it is the "first discovery" or find.
Early humans and art The engraving shows part of a figure of a horse, and was made by stone age people (modern humans) towards the end of the last ice age.
Although these people were hunter-gatherers, living before agriculture and domestication of animals had begun, they were nevertheless skilled technicians and artists. In the 1800s very little was known about the early history of humans, especially the fact that our species had been around for many hundreds of thousands of years, along with relatives such as the Neanderthals. So the significance of discoveries like the Neschers antler largely went unrecognised at the time.,/i>
Fine
Since the late 1800s many other carved objects, along with painted caves, have been discovered that show evidence of the art which early humans were creating.
The oldest examples of representational art found so far are ivory figurines of animals and humans from early Aurignacian (Upper Palaeolithic) sites in Germany, dated at 35-40,000 years.
At the end of the day, this is very poorly written.
The article should say, and the news here is; Representational art older than pictorial art, as far as we can tell.
Or
Simply say we found some really cool old art that had been overlooked for nearly 200 years.
