Around 95% of all living species died out--a global catastrophe far greater than the dinosaurs' demise 65 million years ago. How this happened remains a mystery. But there are many competing theories. Some blame huge volcanic eruptions that covered an area as large as the continental United States; others argue for sudden changes in ocean levels and chemistry, including burps of methane gas; and still others cite the impact of an extraterrestrial object, similar to what caused the dinosaurs' extinction.\u003c\/p\u003e","brand":"Douglas H Erwin","offers":[{"title":"Default Title","offer_id":44217304776764,"sku":"9780691005249","price":1447.5,"currency_code":"PKR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0714\/7706\/7836\/files\/extinctionhow-life-on-earth-nearly-ended-250-million-years-ago-9780691005249.jpg?v=1776762986","url":"https:\/\/libertybooksstore.myshopify.com\/products\/extinctionhow-life-on-earth-nearly-ended-250-million-years-ago","provider":"LibertyBooksStore","version":"1.0","type":"link"}
