Aptian extinction

The Aptian extinction was an

geological time scale
, and has sometimes been termed the mid-Aptian extinction event as a result.

It is classified as a minor extinction event, rather than a major event like the famous

Mesozoic Era. The Aptian event is most readily detected among marine rather than terrestrial fossil deposits. Nonetheless, "From a palaeobotanical perspective, the Aptian Extinction Event is an episode of importance, deserving a higher status among other minor events."[1]

The Aptian event may have been causally connected with the

Ma
, India was located in the southern Indian Ocean; plate tectonics had not yet moved the Indian landmass into its present position.) Note that the
mammals went extinct around this time too. These extinctions may be associated with this event.[citation needed
