利用埃及Gebel Maghara的腕足类和牡蛎壳的稳定同位素(Delta O-18，Delta C-13)分析，重建了第一个详细的中、晚侏罗世赤道附近水温数据集。在整个时间间隔内，温度保持相对恒定，平均温度约为25.7摄氏度。巴索尼亚早期的气温略有上升(类似于27.0摄氏度)，而基默里季亚的气温最低(类似于24.3摄氏度)。正如对热带古纬度的预期，季节性很低(
Stable isotope (delta O-18, delta C-13) analyses of brachiopod and oyster shells from the Gebel Maghara, Egypt, were used to reconstruct the first detailed dataset on peri-equatorial water temperatures during the Middle to Late Jurassic. Throughout this time interval, temperatures remained relatively constant around an average of 25.7 degrees C. Slightly warmer conditions existed in the Early Bathonian (similar to 27.0 degrees C), while the Kimmeridgian shows the lowest temperatures (similar to 24.3 degrees C). As expected for a tropical palaeolatitude, the seasonality was very low (
