[b]Ammonites from the Oxfordian-Kimmeridgian boundary and the Lower–Upper Kimmeridgian of Kachchh, western India[/b]
Journal Title: Volumina Jurassica - Year 2013, Vol 11, Issue 1
Abstract
Several new specimens of ammonites from the Oxfordian and Kimmeridgian of Kachchh, western India, are described and illustrated. The Oxfordian ammonites ?[i]Subdiscosphinctes [/i]Malinowska, [i]Perisphinctes[/i] Waagen, [i]Dichotomoceras [/i]Buckman, and ?[i]Larcheria [/i]Tintant, all from Bharodia in the Wagad Uplift, enable tentative biochronostratigraphic correlations with the uppermost Middle Oxfordian up to the lower Upper Oxfordian of the unified Submediterranean zonation, whereas the Kimmeridgian ammonites [i]Streblites[/i] Hyatt, “[i]Orthosphinctes[/i]” Schindewolf, [i]Torquatisphinctes [/i]Spath, [i]Pachysphinctes [/i]Dietrich, [i]Katroliceras[/i] Spath, [i]Aspidoceras [/i]Zittel, and [i]Schaireria [/i]Checa reconfirm a stratigraphic gap embracing incompletely known parts of the uppermost Oxfordian and the Lower Kimmeridgian as known from the ammonite records of the Kachchh Mainland of the Kachchh Basin.
