This discovery also suggests that on the coast of northeastern Brazil, dyrosaurids replaced the pre-existing Late Cretaceous fauna of diversified mosasaurs, a group of marine lizards, after the K\u2013P extinction event, becoming the main predators, together with sharks, in shallow marine Palaeocene environments. More detailed stratigraphic records and detailed dating of the deposits with dyrosaurids are necessary to correlate this particular pattern found in the ancient northeastern Brazilian coast within the evolution of the group, especially in Africa.<\/jats:p>","DOI":"10.1098\/rspb.2008.0110","type":"journal-article","created":{"date-parts":[[2008,3,26]],"date-time":"2008-03-26T00:11:12Z","timestamp":1206490272000},"page":"1385-1391","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":85,"title":["New dyrosaurid crocodylomorph and evidences for faunal turnover at the K\u2013P transition in Brazil"],"prefix":"10.1098","volume":"275","author":[{"given":"Jos\u00e9 Antonio","family":"Barbosa","sequence":"first","affiliation":[{"name":"Department of Geology\/LAGESE, Universidade Federal de PernambucoRua Acad\u00eamico H\u00e9lio Ramos, s\/n, Recife, PE 50740-530, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander Wilhelm Armin","family":"Kellner","sequence":"additional","affiliation":[{"name":"Paleovertebrate Sector, Department of Geology and Paleontology, Museu Nacional\/Universidade Federal do Rio de JaneiroQuinta da Boa Vista, S\u00e3o Crist\u00f3v\u00e3o, Rio de Janeiro, RJ 20940-040, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Som\u00e1lia Sales","family":"Viana","sequence":"additional","affiliation":[{"name":"Universidade Estadual Vale do Acara\u00faAvenida da Universidade, 85, Bet\u00e2nia, Sobral, CE 62040-370, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2008,3,25]]},"reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-3121.1994.tb00509.x"},{"key":"e_1_3_2_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0016-6995(87)80061-X"},{"key":"e_1_3_2_4_1","doi-asserted-by":"publisher","DOI":"10.1080\/10292389409380462"},{"key":"e_1_3_2_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1096-3642.2005.00152.x"},{"key":"e_1_3_2_6_1","doi-asserted-by":"publisher","DOI":"10.1080\/02724634.1996.10011283"},{"key":"e_1_3_2_7_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0022336000057875"},{"key":"e_1_3_2_8_1","doi-asserted-by":"crossref","first-page":"237","DOI":"10.3406\/geolm.1978.1046","article-title":"Les Dyrosauridae (Crocodylia, Mesosuchia) des phosphates de l'Eoc\u00e9ne inf\u00e9rieur de Tunisie: Dyrosaurus, Rhabdognathus, Phosphatosaurus","volume":"5","author":"Buffetaut E","year":"1978","journal-title":"G\u00e9ologie M\u00e9diterran\u00e9enne"},{"key":"e_1_3_2_9_1","doi-asserted-by":"crossref","first-page":"262","DOI":"10.1127\/njgpa\/156\/1978\/262","article-title":"Crocodilian remains from the Eocene of Pakistan","volume":"156","author":"Buffetaut E","year":"1978","journal-title":"Neues Jahrb.
