Discovery of seal fossils leads to new revelations

The discovery of the extinct monk seal species came about after an international team of biologists examined seven fossil specimens (including a complete skull) found on south Taranaki beaches in New Zealand between 2009 and 2016.

Named Eomonachus belegaerensis, the new species was about 2.5m long and weighed around 200 to 250kg. It is believed to have lived in the waters around New Zealand three million years ago.

Prehistoric whales got bent

A team of paleobiologists surveyed hundreds of modern and ancient whale skeletons for decompression syndrome, which occurs when quick pressure changes force air or fat bubbles out of blood vessels.

Such damage would have been common when whales first began plunging into the depths of the ocean, says Brian Beatty, of New York College of Osteopathic Medicine in Old Westbury, US, who led the study.
