Interesting article, summarizing ~ 3 thousands of well-dated oxygen isotope record derived from belemnite rostra and bivalve shells through the whole European Jurassic. Some proposed climate oscillations very well corresponding with other climate indicators. These are Late Pliensbachian cooling and Early Toarcian warming, Mid Jurassic cooling and Late Jurassic warming. All these events also could be traced through analysis of ammonite assemblages and other climate indicators (glendonite occurrences in Arctic, restricted by Late Pliensbachian and Middle Jurassic (especially numerous in the Bajocian and Bathonian), changes in palynological spectra etc). Cooling event in the Cl-Oxf transition perhaps has regional significance only and in my opinion caused by current reorganization in Europe, Tithonian cooling also very local and partially could be connected with rarity of belemnite data and using stable isotopes from bivalves; in European Russia and Arctic stable isotope data from belemnites suggesting gradual warming during the whole Late Jurassic with maximum in the Volgian

Thanks to G. Dera for pdf
