{"product_id":"9780253008961","title":"At the Top of the Grand Staircase: The Late Cretaceous of Southern Utah","description":"\u003cp\u003eThe Grand Staircase-Escalante National Monument in Utah is the location of one of the best-known terrestrial records for the late Cretaceous. A major effort in the new century has documented over 2,000 new vertebrate fossil sites, provided new radiometric dates, and identified five new genera of ceratopsids, two new species of hadrosaur, a probable new genus of hypsilophodontid, new pachycephalosaurs and ankylosaurs, several kinds of theropods (including a new genus of oviraptor and a new tyrannosaur), plus the most complete specimen of a Late Cretaceous therizinosaur ever collected from North America, and much more. At the Top of the Grand Staircase: The Late Cretaceous of Southern Utah documents this major stepping stone toward a synthesis of the ecology and evolution of the Late Cretaceous ecosystems of western North America.\u003c\/p\u003e","brand":"Indiana University Press","offers":[{"title":"Default Title","offer_id":47164135375088,"sku":"9780253008961","price":72.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780253008961_p0.jpg?v=1763680813","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780253008961","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
