Earth Science Australia collected this specimen during one of its 14
expedition to western Queensland. The site was a lagoon on the edge of a
11 million year old inland sea. The water at depth in the lagoon lacked
oxygen so creatures dying and sinking into this oxygen poor environment
were well preserved.
While they look like skin they are actually bones inside the flipper of a
large swimming, shark-like, reptile called an ICHTHYOSAUR.
The bones that make up the flipper are called PHALANGES,
the same name given to the finger and toe bones in our hands and feet.
The ichthyosaur skeleton looks like this...
And if we put flesh on the bones... then.. it may have looked like this...

TV looks cool! - however --- All animated dinosaur reconstructions you see
on TV are guesses
at what the creatures may have looked like and how they moved based on
their bones and fossilised footprints.
We have zero evidence on how dinosaurs were coloured.
