Description
Area, 1.1 hectares 2.6 ac Description Green Lane Pit shows a section in the late Jurassic Kimmeridge Clay and contains a unique Aulacostephanus eudoxus Zone ammonite fauna. The Zone includes the ammonite genus Hoplocardioceras otherwise unknown outside of Greenland. Because of the abundant Aulacostephanus and Amoeboceras in these beds they can be assigned to the A. eudoxus Zone, whereas in Greenland the equivalent Hoplocardioceras beds have previously been of uncertain age. The site has also yielded the ammonite Nannocardioceras, which make it possible to correlate very precisely with one important datum within the A. eudoxus Zone the Nannocardioceras beds seen south of the Wash, but only proved at this one site further north. Other Information The site is identified as of national importance in the Geological Conservation Review.
