Question

what, when and who proposed the law of faunal succession and later on who did the changes or modifications in this law?​

Answer 1

Answer:

Faunal succession was documented by Smith in England during the first decade of the 19th century, and concurrently in France by Cuvier (with the assistance of the mineralogist Alexandre Brongniart). Archaic biological features and organisms are succeeded in the fossil record by more modern versions.

Hope it helps!!!!

Answer 2

Answer:

The principle of faunal succession, also known as the law of faunal succession, is based on the observation that sedimentary rock strata contain fossilized flora and fauna, and that these fossils succeed each other vertically in a specific, reliable order that can be identified over wide horizontal distances.

This law was proposed by William Smith in England during the first decade of the 19th century
