Conifers: Sphenolepis (SFEN-oh-LEP-iss), Athrotaxopsis (ATH-row-tax-OP-siss) and "Sequoia" ambigua (seh-QUOY-ah am-BIG-you-ah)
The forests in this area were dominated by tall conifer trees known from many fossil tree trunks and foliage. Two of the most common trees, Sphenolepis and Athrotaxopsis, were related to modern cypresses, which can survive frequent flooding and even grow in standing water.
Another conifer, "Sequoia" ambigua, had foliage and cones that are similar to those of the modern redwood, prompting 19th century scientists to classify it as a Sequoia. We now know that it was not a true Sequoia, although it may be a relative.
