  • Vísindamenn við UC Berkeley fundu nærri 80 tegundir af ávöxtum og fræjum sem varðveittust undir fornu eldfjallaösku fyrir um 74,6 milljónum ára.
  • Niðurstöðurnar, sem birtust á miðvikudag í Science, vefengja þá langvarandi skoðun að blómstrandi plöntur hafi náð yfirráðum fyrst eftir fjöldautrýminguna fyrir 66 milljónum ára.
  • Þessi "grasagarðs-Pompeii" bendir til þess að risaeðlur og önnur dýr á krítartímabilinu hafi þegar verið að dreifa fræjum í þéttum, þroskuðum skógum, samkvæmt rannsókninni.
