Geology picture-a-day week continues here at Georneys. Today’s picture shows an impressive boulder of coral on a beach in Barbados. The lowermost part of the boulder has been undercut by wave erosion, providing a perfect nook for some geology students to take a closer look at the fossilized coral preserved in the boulder. The top part of the boulder has some soil and vegetation that has developed– a miniature island ecosystem!
I visited this Barbados beach in 2009 as part of a class field trip for the Geodynamics Course at Woods Hole Oceanographic Institution. Graduate school is hard work sometimes, but the field trips have definitely been a nice benefit! As part of the yearly Geodynamics Course, I’ve been on three field trips– one to Costa Rica, one to Barbados, and one to Switzerland and Italy.
Here’s a closer look at the fossilized coral in the boulder in the above picture:
