New fossils surface all the time. Plesiosaur fossils have been getting exposed, here and there, and then eroded to dust, for many tens of millions of years, and will continue for longer.

Eventually, unless prevented, the sun will engulf Earth.

They are aquatic so most of the fossils will be located under the oceans and seas. We can only find these ones because the area was once a shallow sea that has since drained due to the sea level falling.

So, it can't be preserved digitally, like shown in star wars prequel.
