Christopher Lampton chronicles the scientific detective work behind the Alvarez impact theory, detailing how a thin layer of iridium found worldwide in the geological record became the key piece of evidence pointing to a cataclysmic collision between Earth and a massive extraterrestrial object. Written in an accessible and engaging tone, the narrative illustrates how scientific theories are formed, debated, and tested, making complex paleontological and geological concepts approachable for curious young minds. The result is an authoritative yet captivating introduction to one of the greatest mysteries in the history of life on Earth.\u003c\/p\u003e","brand":"Secondhand Stock","offers":[{"title":"Default Title","offer_id":48887914266843,"sku":"2026770002167-SECONDHAND","price":15.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0523\/7646\/9701\/files\/501f28ac-e106-4361-a9ac-0963f603208a.png?v=1781748940","url":"https:\/\/bookgrocer.com\/products\/2026770002167-secondhand-mass-extinctions-one-theory-of-why-the-dinosaurs-vanished","provider":"Book Grocer","version":"1.0","type":"link"}
