Excavations in Wyoming - page 2

Hello,

Gazelles and grasshoppers, our curious but shy companions during our work. They are looking at the intruders. And we can only now and then look at them, because we have to analyse the geological sediments in the sections around us.

Christian Dupuis and Etienne Steurbaut are collecting samples which allow us to determine the proportion of CO2 in the atmosphere, 55 million years ago. At that date, there used to be a subtropical climate in Wyoming (just as in Belgium).

Our American colleague Philip Gingerich and Hugo De Potter are recording the GPS co-ordinates and the altitude of each site where we are looking for fossils and they are mapping all these data. Without GPS you can’t identify with precision a specific site in the desertlike badlands of the Big Horn Basin : from north to south, the Basin extends over more than 250 km. Doesn’t take much to get lost in there.

See you,

Thierry
