So there is actually no metamorphism that takes place in the bulk of the terranes. I would imagine some would happen along the margins but I don’t know if any fossils would survive that amount of pressure. Then again, it’s probably a case by case scenario. Attached is a Thalattosaur centrum from the Izee Terrane of Oregon (Carnian Triassic). The skeletons were found by Gloria Carr of the North America Research Group. Prep-work is being done at the Oregon Museum of Science and Industry and the fossils are being described at the University of Alaska. The fossils belong to the Oregon Museum of Natural and Cultural History at the University of Oregon. 3D prints of the fossils are also used at OMSI.
