Yes, completely overstated. The 2009 paper on the supernova causing the Ordovician extinction (https://arxiv.org/pdf/0809.0899) has always been viewed skeptically, even for a paleontology paper. The Ordovician extinction has always been contentious. There's evidence of a severe ice age, but ocean water temperature proxies don't line up. There's even a "It didn't happen" faction among paleontologits. There's probably 4 other plausible theories for that particular mass extinction, including 2 kinds of volcanism, dust influx from the L-Chondritic parent body breakup causing the ice age, land…

I kind of expected the article to at least mention the end Ordovician Extinction by gamma ray burst theory: http://arxiv.org/abs/0809.0899 http://arxiv.org/abs/astro-ph/0309415 http://arxiv.org/abs/1409.7049
