A research team in China recently determined that four large dinosaur teeth discovered in the Sanshui Basin in South China's Guangdong province belong to the same group of carnivorous, bipedal dinosaurs as Tyrannosaurus rex.
中國(guó)的一個(gè)研究小組最近確定,在中國(guó)南方廣東省三水盆地發(fā)現(xiàn)的四顆大型恐龍牙齒與霸王龍屬于同一類(lèi)肉食性雙足恐龍。

This finding was published in the international geological journal Cretaceous Research on Thursday.
這一發(fā)現(xiàn)周四發(fā)表在國(guó)際地質(zhì)雜志《白堊紀(jì)研究》上。

Xing Lida, an associate professor at China University of Geosciences Beijing, who led the research, said the fossilized teeth found in the cities of Sihui and Guangzhou date back to the end of the Late Cretaceous period, approximately 66 to 70 million years ago.
領(lǐng)導(dǎo)這項(xiàng)研究的中國(guó)地質(zhì)大學(xué)北京分校副教授邢立達(dá)表示,在四會(huì)和廣州發(fā)現(xiàn)的牙齒化石可以追溯到晚白堊世末期,距今約66至7000萬(wàn)年。

South China lacks evidence of large theropod dinosaurs from the Late Cretaceous, with the teeth found in the basin marking the first discovery of large theropod dinosaurs in the area and one of the southernmost fossil records of the Tyrannosauroidea in China.
華南地區(qū)缺乏晚白堊世大型獸腳亞目恐龍的證據(jù),盆地中發(fā)現(xiàn)的牙齒標(biāo)志著該地區(qū)首次發(fā)現(xiàn)大型獸腳亞目恐龍,也是中國(guó)最南端的霸王龍化石記錄之一。

It is also one of the most recent records of the Tyrannosauroidea in China, Xing said.
邢說(shuō),這也是中國(guó)對(duì)暴龍科的最新記錄之一。

He said dinosaur egg fossils from the Late Cretaceous period discovered in the basin also indicate that dinosaurs belonging to groups including the Troodontidae, Oviraptorosauria and Hadrosauridae lived in the region.
他說(shuō),在該盆地發(fā)現(xiàn)的白堊紀(jì)晚期的恐龍蛋化石也表明,傷齒龍科、偷蛋龍科和鴨嘴龍科等恐龍?jiān)钤谠摰貐^(qū)。

"The discovery of teeth from the Tyrannosauroidea alongside these taxons forms a dinosaur biota, suggesting that the dinosaur biota in southern China was likely quite prosperous toward the end of the Cretaceous before the major extinction event," Xing said.
邢說(shuō):“在暴龍總科中發(fā)現(xiàn)的牙齒與這些分類(lèi)群一起形成了恐龍生物群,這表明中國(guó)南方的恐龍生物群可能在白堊紀(jì)末重大滅絕事件之前相當(dāng)繁榮。”

Xing said theropod dinosaur teeth typically have a banana or crescent shape, wider in the middle and narrower toward the edges. The three relatively intact teeth found in Sihui each exceed 6 centimeters in crown length, while tooth fragments were found in Guangzhou.
邢說(shuō),獸腳類(lèi)恐龍的牙齒通常呈香蕉形或新月形,中間較寬,邊緣較窄。 四會(huì)發(fā)現(xiàn)的三顆相對(duì)完整的牙齒,冠長(zhǎng)均超過(guò)6厘米,而廣州則發(fā)現(xiàn)了牙齒碎片。

The research team, with members from China University of Geosciences Beijing, the Sihui City Museum, Sun Yat-sen University and the Guangdong-Hong Kong-Macau Institute of Earth Sciences, analyzed 145 features from 97 theropod species, with the results supporting the classification of the four teeth as belonging to the Tyrannosauroidea.
由中國(guó)地質(zhì)大學(xué)(北京)、四會(huì)市博物館、中山大學(xué)和粵港澳地球科學(xué)研究所等單位組成的研究小組,對(duì)97種獸腳類(lèi)恐龍的145個(gè)特征進(jìn)行了分析,結(jié)果支持了分類(lèi) 屬于暴龍科的四顆牙齒。

The primary author of the paper, doctoral student Wang Donghao from China University of Geosciences Beijing, estimated that the dinosaur to which the teeth found in Sihui belonged was at least 5 to 6 meters long.
該論文的主要作者、北京地質(zhì)大學(xué)的博士生王東浩估計(jì),四會(huì)發(fā)現(xiàn)的牙齒所屬的恐龍至少有5至6米長(zhǎng)。
