建昌发现一新种翼龙_我的网站

A |     近日，《巴西科学院院刊》在线发表了由中国科学院古脊椎动物与古人类研究所汪筱林研究员和巴西国家博物馆Alexander A. W. Kellner教授领导的中国—巴西古生物团队合作研究的最新成果。这项研究报道了产自我市建昌玲珑塔的悟空翼龙科的化石为一新种，并命名为坎波斯达尔文翼龙。该发现进一步丰富了悟空翼龙科的多样性，为研究该类群的系统发育和演化提供了新的证据。         建昌县有着悠久的地质历史，全县28个乡镇22个有古生物化石资源，出露了近20亿年以来的元古代、古生代、中生代及新生带地层。距今1亿多年的中生代地层中，富含“燕辽生物群”和“热河生物群”化石。    Manila, Oct 21 (UNI) "The pandemic is not yet over," a World Health Organization (WHO) official warned on Friday, saying the continued emergence of subvariants "poses a risk of resurgence and overwhelming health systems."



Babatunde Olowokure, director of Health Security and Emergencies for WHO in the Western Pacific, said Singapore and New Zealand are experiencing surges of Covid-19 cases, while Philippines, South Korea, Japan, Mongolia, and Vietnam have shown a sustained decline of cases, hospitalization, and deaths since August.



Olowokure told a press conference that the circulation of Covid-19 Omicron XBB subvariant is fueling the surge in Singapore, while the BA.5 is still the dominant variant in New Zealand.



"Singapore reimposed public health safety measures such as limiting visitors in hospitals and residential care homes," he said.



WHO data showed that the Western Pacific Region tallied over 92 million confirmed Covid-19 cases, including more than 270,000 deaths since the highly infectious and fatal disease emerged in 2020.



Olowokure said the decline of cases in several countries is due to "relatively high vaccine coverage," but he urged people to remain vigilant despite the decline in reported cases regionally and globally, adding that the coronavirus continues to circulate in the region.
