History of Palaeozoic Forests

Conifers

Early conifers looked very similar to the modern genus Araucaria. However, the cones were completely different. The earliest forms are known from the middle Westphalian and by the end of the Westphalian they may be locally common. Nevertheless, they are usually very rare elements in Carboniferous floras. One example shows a typical conifer from the famous Hamilton Quarry in Kansas which also yielded many vertebrate remains.
