Such patterns are common today in wild populations of long-lived birds and mammals. Factors such as predation and entrance into the breeding population may have influenced tyrannosaur survivorship. This survivorship pattern can explain the rarity of juvenile specimens in museum collections.\n          <\/jats:p>","DOI":"10.1126\/science.1125721","type":"journal-article","created":{"date-parts":[[2006,7,13]],"date-time":"2006-07-13T22:14:54Z","timestamp":1152828894000},"page":"213-217","source":"Crossref","is-referenced-by-count":105,"title":["Tyrannosaur Life Tables: An Example of Nonavian Dinosaur Population Biology"],"prefix":"10.1126","volume":"313","author":[{"given":"Gregory M.","family":"Erickson","sequence":"first","affiliation":[{"name":"Department of Biological Science, Florida State University, Tallahassee, FL 32306, USA."},{"name":"Department of Biological Sciences, University of Alberta, Alberta T6G 2E, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philip J.","family":"Currie","sequence":"additional","affiliation":[{"name":"Department of Biological Science, Florida State University, Tallahassee, FL 32306, USA."},{"name":"Department of Biological Sciences, University of Alberta, Alberta T6G 2E, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian D.","family":"Inouye","sequence":"additional","affiliation":[{"name":"Department of Biological Science, Florida State University, Tallahassee, FL 32306, USA."},{"name":"Department of Biological Sciences, University of Alberta, Alberta T6G 2E, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alice A.","family":"Winn","sequence":"additional","affiliation":[{"name":"Department of Biological Science, Florida State University, Tallahassee, FL 32306, USA."},{"name":"Department of Biological Sciences, University of Alberta, Alberta T6G 2E, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"221","reference":[{"key":"e_1_3_1_2_2","first-page":"271","volume":"15","year":"1998","unstructured":"P.
