1. Palm Fronds Marker

Inscription.

Large palm fronds show that the climate was much warmer than that of today. Other plant and tree types found here, such as extinct relatives of sycamore, walnut, paddle-leafed ginger and an ancient relative of the avocado, lost their leaves seasonally.

Temperatures, moderated by the seaway to the east, seldom dropped below freezing. Humidity from the seaway, lakes and swamps contributed to rainfall that produced abundant vegetation.
