Description :
A brief cold-warm-cold climate change during the middle Wisconsinan is described for the first time in North America, based on fossil beetle assemblages at Titusville, Pennsylvania. AMS dating of insect chitin and wood suggests the change occurred between 39,000 and 43,500 yr B.P. These data are correlated with other data to obtain a better understanding of middle Wisconsinan paleoclimate in northeastern United States.
