I have often wondered how to make this clear wrt science communication
Eg much is not known about dinosaurs. Many things cannot be found in fossils (obligatory xkcd: https://xkcd.com/1747/)
How do you communicate what is unknown or what can't be known?
My favorite dinosaur theory is they looked far more like a plump turkey than a Komodo dragon.
We tend to just drape a bounding skin volume over the bones and give it a color, MAYBE some feathers.
But a whale skeleton looks nothing like the mass of flesh of a whale. Skeletons give no clue about an Elephant’s head shape.
So imagine a huge fluffy owl or yellow chick with a trex skeleton deep inside.
