Middle Jurassic radiolarians have been recovered from the western Pacific for the first time. The oldest faunas are assigned to the middle and upper Tricolocapsa conexa Zone, indicating a Bathonian/Callovian age. The faunas contain more than 30 species and are characterized by an abundance of small nassellarians with a constricted distal end. The faunas compare well with Tethyan faunas, and are...

Before its collision with Eurasia1–5, the Indian Plate moved rapidly, at rates exceeding 140mmyr−1 for a period of 20 million years1,3–7. This motion is 50 to 100% faster than the maximum sustained rate of convergence of themain tectonic plates today8. The cause of such high rates of convergence is unclear and not reproduced by numerical models9,10. Here we show that existing geological data11,...

Abstract The Capitanian (Middle Permian) mass extinction event, prior to and separate from the end-Permian extinction, has been suggested as a severe biotic crisis comparable big five extinctions of Phanerozoic. However, there is still controversy about its global significance. In particular, this purportedly disastrous event in was mostly documented eastern Tethys, especially South China Japan...

Geminate species are morphologically similar sister-species found on either side of the Isthmus of Panama. The existence of all geminates in the tropical Eastern Pacific ocean and the Caribbean Sea is most often explained by vicariance: closure of the Central American Seaway 3.1 to 3.5 Ma simultaneously isolated populations of species with amphi-American distributions. In this paper, we test th...
