Feild TS, Upchurch GR, Chatelet DS, Brodribb TJ, Grubbs KC, Samain MS, Wanke S. 2011. Fossil evidence for low gas exchange capacities for Early Cretaceous angiosperm leaves. Paleobiology 37 (2): 195-213

The photosynthetic gas exchange capacities of early angiosperms remain enigmatic. Nevertheless, many hypotheses about the causes of early angiosperm success and how angiosperms influenced Mesozoic ecosystem function hinge on understanding the maximum capacity for early angiosperm metabolism. We…
