Expressing bad attitudes to science without realising it

The Piltdown Man Hoax

This fortuitous find – nine pieces of a large-brained human skull and an ape-like lower jaw with two teeth – was readily accepted by the British establishment due to their belief that a large brain was one of the first human features to evolve. 1912 - Piltdown Man ‘discovered’ in England. - The Australian Museum

This is what you originally wrote, with added emphasis:

Another evidence was the realisation that a number of fossils of early man were intentionally falsified and made to look ape like when in fact they did not look anything like what was claimed! One of these “cons” went on for a number of decades and is still on display despite the publicly recognised and proven gross error it contains!

You said there were a number of intentionally falsified fossils. You’ve only provided one.

You said it is still on display. It’s not on display. The original in London is locked away; the one in Australia is a copy.

You said it is on display “despite the publicly recognised and proven gross error” - but it’s not, because it’s on display as a hoax, not as a real fossil find, and the recognised error is acknowledged in the display.

If all you have is one example of which a copy is on display as a hoax, then you were lying.
