“The paleontological discover signifies an episode of extraordinarily fast sea degree change within the space of the northernmost archipelago of Eurasia, which occurred in the previous couple of thousand years,” he stated.
The expedition is being performed from an Russian ice-strengthened vessel known as Professor Molchanov and can proceed via August, based on Russian state information company TASS.
