Belemnites are the backbone of Jurassic-Cretaceous reconstruction as they able to determine former seawater properties, such as temperature.

In 2010 EGU held our first annual Photo Competition at the General Assembly in Vienna. Since then hundreds of photos have been shared on imaggeo by geoscientists and researchers just like you, with a lucky few being selected each year to be highlighted during the meeting and voted on by our members. These images can be of anything to do with geology or geoscience – we get many beautif ...[Read More]
