Furthermore, this liquid aesthenosphere, which continues to create new crust at rifting zones such as the mid oceanic ridges, melts down subducting crust as the residue of this crust is drawn deeper into the mantle.
While volatiles trapped in the remaining crustal residue are ultimately assimilated into the mantle, lighter volatiles from the crustal melt are fractionated and float up towards the surface to feed plate margin volcanoes.
“It’s not just the texture of the skin, some of the organics are still there,” said Brown.
The nodosaur fossil is currently being displayed at Alberta’s Royal Tyrell Museum of Paleontology.
