New fossil assemblage with amber, plants and vertebrates from the lower Cenomanian near Châtellerault (Vienne, western France)
Abstract Trees are an obvious component of most landscapes. Artists' views of Mesozoic landscapes regularly feature modern trees such as firs ( Abies and Picea ) and monkey-puzzle trees ( Araucaria araucana ). However, these reconstructions are highly hypothetical and, in reality, very little is known about the silhouettes of Mesozoic trees. In Mesozoic (Middle Jurassic to Early Cretaceous) strata of Thailand, large conifer logs with different types of architecture are evident, a rare opportunity for architectural studies. Various methods to estimate the original diameter and height of the trees are assessed. Among our material some trees have the classical Christmas-tree shape, whereas others are more oak-like in silhouette. All these trees lived in forest environments. Tree shape is strongly related to environment, and is still under-used as a palaeoecological tool. Reconstructing trees and vegetation has wide implications, from evaluating dinosaur herbivory to calculating elements of the carbon cycle.
