In the mid-70s of the twentieth century, during the work of builders in the city of Ayud, interesting finds were found, the bones of elephants, dating back more than 2.5 million years, and an aluminum wedge was also found.
If the first finds did not cause controversy and doubts, then the aluminum find left a bunch of questions, the ratio of the alloy raises questions, because almost more than 90% of the wedge consists of aluminum, and modern history knows this alloy since the end of the 19th century! Speaking of production, it did not exist in general exactly in the form in which it appears in relation to the composition of the found object.
Given this, many believe that the Ayud artifact was planted, but here's an interesting fact: the Ayud object has a plaque thickness of about a millimeter, which suggests that it dates back tens of millions of years.
Unfortunately, so far not a single reason has been found how such an object could have ended up there, what it was used for, and the point of view is being considered that it could have been planted.
It is believed that the archaeological item is currently in a private collection. However, the secret of its origin has not yet been revealed: is it real or is it someone's joke? What do you think?
