The titanosaur group is one of the most diverse among dinosaurs, but only 3 of the 70 genera have complete skulls like that of <em>T. macedoi<\/em>. Furthermore, most of the skull fragments are from more recent titanosaurs, from the Late Cretaceous Period. A team led by biologists Hussam Zaher of the University of S\u00e3o Paulo and Jeffrey Wilson of the University of Michigan in the United States found unique features in the skull of <em>T. macedoi<\/em>, such as the shape of the teeth, and concluded that the animal\u2014named after Ubirajara Alves Macedo, a non-academic researcher in the region\u2014was one of the most primitive of the group. <em>T. macedoi<\/em> is thought to have lived 125 million years ago during the Lower Cretaceous, around the same time as other primitive (or basal) titanosaurs, whose fossils have been found in present-day Thailand and Laos in Asia, and Malawi in Africa. Its skull is elongated like that of a horse, with nostrils at the top. The shape of the teeth indicates that the animal\u2014a herbivore estimated to have been 13 meters long, 4 meters tall and weighing 10 tons\u2014likely ate leaves that it plucked off tree branches.<\/p>\n","protected":false},"excerpt":{"rendered":"Skull discovered in Minas Gerais is the oldest titanosaur in South America","protected":false},"author":475,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[168],"tags":[202,241],"coauthors":[785],"class_list":["post-229007","post","type-post","status-publish","format-standard","hentry","category-technoscience","tag-archaeology","tag-history"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/229007","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=229007"}],"version-history":[{"count":0,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/229007\/revisions"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=229007"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=229007"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=229007"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=229007"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
