Eocene Florida Plant Remains = Rethink Local Geology A Little

ResearchBlogging.orgSometimes interesting scientific evidence shows up in unexpected places. Years ago, there had been discussion of the possibility that immediate post glacial climate in the North Atlantic coastal region was unusually warm, but the evidence was spotty. Then, I was looking through material taken from a geotechnical boring placed to assess the geology of a part of Boston Harbor where a new tunnel was being planned, and found a large fragment of a clam embedded in clay. The clay was deposited during the last glacial maximum and later, and was associated with the melting of glaciers in the region. As a matter of routine, I gave it to Russell Barber, a mollusk expert and, at the time, my boss. He identified it as a species of razor clam found these days no farther north than the Carolinas. And thus, yet another piece of spotty evidence!
