Cool Science.

Ichthyosaurs survived longer than previously thought.

This work shows that the ichthyosaurs were not subject to a major extinction at the end of the Jurassic era (145 million years ago). It furthermore also shows that the ichthyosaurs remained very diversified until their definitive extinction, around 94 million years ago. These two results, springing from joint work produced by university and museum researchers in Belgium, the United Kingdom and Germany, and published in the Tuesday, January 3, 2012 edition of the open access journal PLoS One, contradicts earlier theories which considered the cretaceous ichthyosaurs as the final survivors of a group in its death throes.
I wonder what caused their extinction?
