Fossilized Leaf

Caption

This is a fossilized leaf of Vitis stantonii, a grapelike plant from the Hell Creek Formation in North Dakota. Blonder is especially interested in the venation network of each leaf, because veins may be a very good proxy for temperature via their role in constraining leaf water usage. "Fortunately many fossils have exquisite preservation of veins," he said.
