08334 - Nicely Prepared 1.16 Inch Parahomalonotus planus Lower Devonian Graptolites Eoleonaspis

Eoleonaspis

This specimen is preserved in its completeness

Brown-pleochroic euhedral to subhedral hornblende crystals are abundant (Figs

They lived during the Middle-Late Jurassic Epochs and serve as an biostratigraphic index fossil for that time period

Brochantitie forms mainly in exposed areas where weathering prevents accumulation copper ions and enhancement in the acidity of water films

08334 - Nicely Prepared 1.16 Inch Parahomalonotus planus Lower Devonian Graptolites EoleonaspisExtremely rare species.
