The four new described species of serpents have added 70 million years to the evolutionary history of these reptiles. Before this, herpetologists had evidence that snakes had appeared about 100 million years ago, but the new species indicate a far more remote origin. The fossils now presented by an international team of paleontologists suggest that these serpents lived between 167 million and 143 million years ago in different habitats (bogs, pools of water, and riverside or marine systems), during the Middle Jurassic. The largest among them, <em><i>Portugalophis lignites<\/i><\/em>, which was about 1 meter long, was discovered in Portugal. Another, <em><i>Diablophis gilmorei<\/i><\/em>, was retrieved in the state of Colorado, USA. The fossils of <em><i>Parviraptor estesi<\/i><\/em> and <em><i>Eophis underwoodi<\/i><\/em>, the most ancient of the bunch, were found in different locations in England (<em><i>Nature Communications<\/i><\/em>, January 27, 2015). \u201cThe study looks into the idea that evolution within the group we call \u201csnakes\u201d is much more complex than was previously thought,\u201d says Michael Caldwell from the University of Alberta (Canada), main author of the work.<\/p>\n","protected":false},"excerpt":{"rendered":"Described species add 70 million years to the evolutionary history of serpents","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":[231,255,266],"coauthors":[785],"class_list":["post-172583","post","type-post","status-publish","format-standard","hentry","category-technoscience","tag-evolution","tag-paleontology","tag-zoology"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/172583","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=172583"}],"version-history":[{"count":0,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/172583\/revisions"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=172583"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=172583"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=172583"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=172583"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
