Modern Pools and Carboniferous Analogies

Published online by Cambridge University Press:  01 May 2009

Extract

The origin of coal is a difficult problem which is very far from being solved. The Coal Measure flora has long been extinct, and the modern representatives are feeble folk, almost crowded out of existence by plants of very different appearance and internal structure. The modern marsh flora is not primitive but secondary, and consists almost entirely of land plants which have taken to the water habitat again, just as the whale, porpoise, and seal are land animals which have gone back to rejoin their remote ancestral relatives in the sea. Homologous comparisons between past and present are therefore practically impossible, but some common pool developments of to-day may provide useful analogies if nothing more.
