The discovery was made by a multidisciplinary team of researchers from Canada and Japan, who analyzed a fossilized bone of <em>Centrosaurus apertus<\/em>, a species known for its large, distinctive nasal horn. Found in 1989 in Dinosaur Provincial Park, Alberta, the fibula was badly misshapen, initially attributed to a healed fracture. In 2017, pathologists and paleontologists decided to reexamine the fossilized bone, having noticed some unusual characteristics. They examined tissue samples under a microscope and compared tomography images to those of a human fibula affected by osteosarcoma and a healthy <em>Centrosaurus,<\/em> concluding that the diseased bone belonged to an adult dinosaur with advanced cancer (<em>Lancet Oncology<\/em>, August). &#8220;The cancer would have had crippling effects on the individual and made it very vulnerable to the formidable tyrannosaur predators of the time,&#8221; paleontologist David Evans of the Royal Ontario Museum told the McMaster University magazine <em>Brighter World<\/em>. According to the authors, it is the first confirmed case of a malignant tumor in a dinosaur.<\/p>\n","protected":false},"excerpt":{"rendered":"An herbivorous dinosaur that lived about 76 million years ago in what is now the province of Alberta in western Canada had highly aggressive bone cancer in its right hind leg","protected":false},"author":475,"featured_media":383264,"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-381039","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\/381039","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=381039"}],"version-history":[{"count":4,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/381039\/revisions"}],"predecessor-version":[{"id":383350,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/381039\/revisions\/383350"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media\/383264"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=381039"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=381039"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=381039"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=381039"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
