01 - This fossil is remarkably well
preserved because you can see not only the bone structure but also
the more delicate parts such as the fins and tail.
02 - It is already rare enough to find a
fossil of bones and other remnants of animals, but to find a
footprint is even more rare.
03 - Here is a more "standard"
fossil because it is made up of the hard parts of the animal in
question - in this case, a turtle. This kind of fossil proves
that organisms such as certain species of turtle have not changed
much for millions of years.
04 - This is a life-sized model of a
dinosaur set up in an open-air museum in the south of France.
05 - This photo shows a plaster cast
reproduction of the famous fossil "Archaeopteryx" which is
the missing link between dinosaurs and birds. This fossil has
characteristics of both dinosaurs and birds (notice the
feathers). The original fossil is in the Museum of Natural
History in London.
