Fossils reveal 'latitudinal traps' that increased extinction risk for marine species‎

A new study led by researchers at the University of Oxford has shown that the shape and orientation of coastlines significantly influenced extinction patterns for animals living in the shallow oceans during the last 540 million years. In particular, animals living on convoluted or east-west oriented coastlines (such as those found in the Mediterranean and Gulf of Mexico today) were more likely to go extinct than those living on north-south oriented coastlines.
