Detailed explanation-1: -One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents. This suggests that the continents were once joined.
Detailed explanation-2: -They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.
Detailed explanation-3: -The ‘same animal fossils’ found on different continents provide evidence climatic change on continent supporting the theory of ‘continental drift’.
Detailed explanation-4: -Glossopteris. Another type of fossil that provided early support for continental drift was the ancient “seed fern” plant Glossopteris. The leaves of Glossopteris are named for their tongue-like shape (the prefex “glosso-” is Greek for tongue; the suffix “-pteris” refers to a fern).
