Map of North America during the Late Cretaceaous, 85 million years ago, showing one known coastal location of an extinct palm Protoarecoidea bucahanaensis 25 million years after this. (60 Million years ago) Note extensive inland sea in North America at this time. The presence of palm fossils indicate a much warmer and wetter climate 50-60 million years ago, similar to the Gulf coast states today. STAR = Collecting Locality.
