Late Palaeozoic
Abstract As a result of the so-called ‘conquest of the land’, the Late Palaeozoic was the time when a substantial biota of vascular plants and vertebrates became established on the continents, thereby expanding the range of organisms whose biogeography can be studied. As regards plate tectonics, the...
