Marsh Institute Research Scientist Deborah Woodcock was invited by the College of Engineers in Cajamarca to give a lecture entitled “The Piedra Chamana Petrified Forest, Sexi, Cajamarca: A Scientific Resource of Global Importance.” The talk stressed the scientific importance of the site due to its documentation about the vegetation and climate of tropical South America 39 million years ago, when conditions were still quite warm globally but beginning to transition to cooler climates.  It is an extraordinary site with many fossils containing strata including an in-situ forest with trees still in growth position.  The talk was well-attended with some well-known Peruvian paleontologists as well as people from the regional government and office of regional tourism whose involvement in protecting and developing the site we are encouraging.
