Sadly, science is not all it’s cracked up to be, despite the hope it seems to offer. The idea that things are facts is not necessarily factual. This is very true when it comes to looking backwards into the past.
Often what is presented as fact is not, it is assumptions built on assumptions, storytelling & make believe. We are led to believe our modern science is sunny side up when in fact it is just a rotten egg, worthless & broken. It always pays to check the content of things lest you get led astray & ripped off.
"The fragmentary nature of most specimens means that reconstructions often have to be largely speculative, i.e. guesswork, leaving free reign for evolutionary bias." Daniel Anderson.
