Stored at the Museum f\u00fcr Naturkunde Berlin in Germany, the small five-petaled flower lived between 38 million and 34 million years ago and is about three times larger than previous examples. It was collected in 1872 in a boreal forest region of northern Europe that today belongs to Russia and given the scientific name <em>Stewartia kowalewskii<\/em>, from the Teaceae family\u2014the same as tea and camellias\u2014comprising trees and shrubs from temperate and tropical regions. During a postdoctoral fellowship at the museum, German paleobotanist Eva-Maria Sadowski studied the flower using modern microscopy techniques. She extracted pollen grains from the amber and sent them to Christa-Charlotte Hofmann at the University of Vienna, Austria, for analysis. The researchers concluded that the largest flower preserved in amber actually belongs to the genus <em>Symplocos<\/em>, which encompasses trees and shrubs that today grow in tropical and subtropical areas of Asia and the Americas. They renamed the flower <em>Symplocos kowalewskii<\/em> (<em>Scientific Reports<\/em>, January 12). The presence of this genus in northern Europe indicates that the climate there was milder in the distant past.<\/p>\n","protected":false},"excerpt":{"rendered":"Revised description of fossilized flower preserved in amber indicates the climate in northern Europe was milder in the distant past","protected":false},"author":475,"featured_media":0,"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-477755","post","type-post","status-publish","format-standard","hentry","category-notes","tag-paleontology"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/477755","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=477755"}],"version-history":[{"count":1,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/477755\/revisions"}],"predecessor-version":[{"id":477760,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/477755\/revisions\/477760"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=477755"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=477755"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=477755"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=477755"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
