Question

In exploring for coal deposits, geologists sometimes look for fossil indicators: fossilized remains of Carboniferous plants. Which of the following combinations in a sample would suggest the presence of rocks that might bear coal beds?

1. mosses and liverworts, but no vascular plants
2. angiosperms and mosses
3. lycophytes and gymnosperms
4. lycophytes and tree ferns

Answer 1

Answer:

During the carboniferous there is a proliferation of plants such as lycopodia and ferns. Theirs remains have generated large carbon deposits worldwide. These experimental plants reach their maximum richness and diversity during the Carboniferous (300-350 million years).
