The latest webpage to be posted, " Late Miocene fish fossils in Utah support accelerated extension and subsidence, not thermal uplift or a continental divide in the Eastern Snake River Plain ", is an elegant and unusual demonstration that paleontology can contribute to the mantle plumes debate. It is interesting to reflect that paleontology also played a key role in the continental drift debate led by Wegener.
They proposed that the Emeishan large igneous province was formed by a subducted slab-like high velocity anomaly at depths of km and argued it was not generated by mantle plume.
