Kellner教授领导的中国—巴西古生物团队合作研究的最新成果。    CAPE TOWN, South Africa -- Angry protesters in Cape Town confronted the king and queen of the Netherlands on Friday as they visited a museum that traces part of their country’s 150-year involvement in slavery in South Africa.King Willem-Alexander and Queen Maxima were leaving the Slave Lodge building in central Cape Town when a small group of protesters representing South Africa's First Nations groups -- the earliest inhabitants of the region around Cape Town -- surrounded the royal couple and shouted slogans about Dutch colonizers stealing land from their ancestors.The king and queen were put into a car by security personnel and quickly driven away as some of the protesters, who were wearing traditional animal-skin dress, jostled with police.The Dutch colonized the southwestern part of South Africa in 1652 through the Dutch East India trading company. They controlled the Dutch Cape Colony for more than 150 years before British occupation. Modern-day South Africa still reflects that complicated Dutch history, most notably in the Afrikaans language, which is derived from Dutch and is widely spoken as an official language of the country, including by First Nations descendants.King Willem-Alexander and Queen Maxima made no speeches during their visit to the Slave Lodge but spent time walking through rooms where slaves were kept under Dutch colonial rule. The Slave Lodge was built in 1679, making it one of the oldest buildings in Cape Town. It was used to keep slaves -- men, women and children -- until 1811. Slavery in South Africa was abolished by the English colonizers in 1834.Garth Erasmus, a First Nations representative who accompanied the king and queen on their walk through the Slave Lodge, said their visit should serve to “exorcise some ghosts.”The Dutch East India Company established Cape Town as a settlement for trading ships to pick up supplies on their way to and from Asia. Slaves were brought to work at the colony from Asian and other African countries, but First Nations inhabitants of South Africa were also enslaved and forced off their land. Historians estimate there were nearly 40,000 slaves in the Cape Colony when slavery ended.First Nations groups have often lobbied the South African government to recognize their historic oppression. They say their story has largely been forgotten in South Africa, which instead is often defined by the apartheid era of brutal forced racial segregation that was in place between 1948 and 1994.First Nations people have a different ethnic background from South Africa's Black majority.___AP Africa news: https://apnews.com/hub/africa。

二 | 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。

三 | 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。

四 |          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。其中，燕辽生物群，已出土动植物化石500多种；热河生物群，已出土动植物化石近千种，多达20个门类。围绕建昌古生物化石的许多重要研究成果，都在国际权威学术期刊《自然》（英国）和《科学》（美国）发表过。         据悉，悟空翼龙科是翼龙目的一科，是群基础翼龙类。

五 | 这一类群此前共发现3属5种，包括李氏悟空翼龙、模块达尔文翼龙、玲珑塔达尔文翼龙、粗齿达尔文翼龙和中国鲲鹏翼龙。

六 | 坎波斯达尔文翼龙的发现，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。
