What are Steno's contributions to geology?
Steno was the first to realize that the Earth's crust contains a chronological history of geologic events and that the history may be deciphered by careful study of the strata and fossils.
He rejected the idea that mountains grow like trees, proposing instead that they are formed by alterations of the Earth's crust..

What did Steno discover?
This is now referred to as Steno's law of superposition: layers of rock are arranged in a time sequence, with the oldest on the bottom and the youngest on the top, unless later processes disturb this arrangement.
It is Steno's most famous contribution to geology..
What did Steno do for evolution?
He argued for the first time that fossils were snapshots of life at different moments in Earth's history and that rock layers formed slowly over time.
It was these two facts that served as the pillars of paleontology and geology in future centuries..
What rule did Steno discover?
From his work in the mountains of western Italy, Steno realized that the principle of superposition in stratified (layered) rocks was the key to linking time to rocks.
In short, each layer of sedimentary rock (also called a “bed”) is older than the one above it and younger than the one below it..
What was Steno first famous for?
Nicholas Steno.
Despite a relatively brief scientific career, Nicholas Steno's work on the formation of rock layers and the fossils they contain was crucial to the development of modern geology.
The principles he stated continue to be used today by geologists and paleontologists..
What was Steno's first principle?
In 1669 Nicolaus Steno made the first clear statement that strata (layered rocks) show sequential changes, that is, that rocks have histories.
From his work in the mountains of western Italy, Steno realized that the principle of superposition in stratified (layered) rocks was the key to linking time to rocks..

Who was the pioneer of the Steno crystallography?
Nicolaus Steno, Danish Niels Steensen or Niels Stensen, (born January 1 [January 11, New Style], 1638, Copenhagen, Denmark—died November 25 [December 5], 1686, Schwerin [Germany]), geologist and anatomist whose early observations greatly advanced the development of geology..

Steno made the leap and declared that the tongue stones indeed came from the mouths of once-living sharks.
He showed how precisely similar the stones and the teeth were. - Steno's Law of Superposition
Steno studied the cliffs and hills of Italy to find the answer.
He proposed that all rocks and minerals were originally fluid.
Floating on the surface of the planet long ago, they gradually settled out of the ocean and created horizontal layers, with new layers forming on top of older ones.
