Tyrannosaurus was an impressive beast; it topped five tons  was more than thirty-five feet (twelve meters) long  and had the largest head and most powerful bite of any land animal  ever. Tyrannosaurs started small  just a couple of yards long  and over the course of 100 million years  evolved into giant meat-slicing bone crushers.  As of 2015  there were nearly 30 described species of tyrannosaur  but during the last decade at least one new species has been identified and named every year  greatly improving what we know about how they lived  fed  bred  and died. THE TYRANNOSAUR CHRONICLES tracks the rise of these dinosaurs  and presents the latest research into their biology  showing off more than just their impressive statistics--tyrannosaurs had feathers  and fought and even ate one another. Indeed  David Hone tells the evolutionary story of the group through their anatomy  ecology  and behavior  exploring how they came to be the dominant terrestrial predators of the Mesozoic--and more recently  one of the great icons of biology.\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":44966151323701,"sku":"ByrdShop_1472911253","price":125.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8139\/0901\/files\/9781472911254.jpg?v=1770555521","url":"https:\/\/atxbooks.com\/products\/the-tyrannosaur-chronicles-the-biology-of-the-tyrant-dinosaurs","provider":"ATX Books","version":"1.0","type":"link"}
