A dip into Triassic seas

MITZPE RAMON, ISRAEL — We wish there was still some water in those seas because it was 41°C (106°F) this afternoon, but alas the only water we saw was that which was warmly sloshing in our plastic bottles.  Today we looked at the Middle Triassic in the southern limb of Makhtesh Ramon as part of a project for Sarah Greene, a graduate student at the University of Southern California.  She is working on fossil shellbeds as indicators of the tempo and mode of the Triassic recovery from the Permian extinctions.  We are providing information from the Gevanim and Saharonim Formations.  The shellbeds were easy to find, describe and measure.
