| Baxter, A.T., Aitchison J.C., Zyabrev S.V., Aliet J.R. (2011) Upper Jurassic radiolarians from the Naga Ophiolite, Nagaland, northeast India // Gondwana Res. doi:10.1016/j.gr.2011.02.001

Radiolarians, extracted from cherts collected from an ophiolitic mélange near Salumi, Nagaland, NE India, have well-preserved tests and can be assigned to the Upper Jurassic (Kimmeridgian–lower Tithonian). These are the first well-preserved and clearly imaged radiolarians reported from the Naga Ophiolite. They are significantly older than fossils previously reported from this mélange, and their ages are similar to those determined radiometrically from associated igneous units
Middle Jurassic - Lower Cretaceous ammonites & aptychi
