The species lived between 75 million and 71 million years ago, when the paleocontinent Gondwana had almost completely split up. Named <em>Stegouros elengassen<\/em>, the herbivore was about 2 meters long and its body was covered with bony plates (<em>illustration<\/em>). The most curious part is its tail. It was flat and shaped like a leaf, made up of seven pairs of bone plates (osteoderms) that projected laterally like a <em>macuahuitl\u2014<\/em>a weapon of war used by the Aztecs and other peoples who inhabited what is now central Mexico. It may have been used for defense. The fossilized skeleton, which was 80% complete, was found in 2018 during excavations in the Magallanes Region in the far south of Chile. The skull of <em>Stegouros elengassen<\/em> shares characteristics with the ankylosaurs, but the body is more primitive, similar to the stegosaurs (<em>Nature<\/em>, December 1). The group, led by Sergio Soto-Acu\u00f1a of the University of Chile, classified the new species as belonging to the ankylosaurs, related to the dinosaurs of the genus <em>Kunbarrasaurus<\/em> from Australia and <em>Antarctopelta<\/em> from Antarctica.<\/p>\n","protected":false},"excerpt":{"rendered":"A new species of armored dinosaur with a very peculiar tail has been described by Chilean paleontologists","protected":false},"author":475,"featured_media":428210,"comment_status":"closed","ping_status":"closed","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":[1651],"tags":[255],"coauthors":[785],"class_list":["post-428575","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-notes","tag-paleontology"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/428575","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=428575"}],"version-history":[{"count":2,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/428575\/revisions"}],"predecessor-version":[{"id":430961,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/428575\/revisions\/430961"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media\/428210"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=428575"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=428575"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=428575"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=428575"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
