Small Dinosaur Suffered From Jaw Tumor
恐龍遺骸驚現(xiàn)腫瘤
For the first time ever, scientists have discovered a tumor in the remains of a dinosaur.
科學(xué)家首次在恐龍的遺骸中發(fā)現(xiàn)了腫瘤。
Researchers at the University of Southampton in England found the deformed jaw of a dinosaur. The smaller-than-normal dwarf dinosaur is called a hadrosaur. It is a duck-billed dinosaur.
英格蘭南安普敦大學(xué)的研究人員發(fā)現(xiàn)一只恐龍的下顎發(fā)生了變形。它的形體小于正常的恐龍，叫做鴨嘴龍。它是一種嘴像鴨子的恐龍。
The hadrosaur lived nearly 67 to 69 million years ago. It was found in what is called the “Valley of the Dinosaurs.” That valley is in the Transylvania area of western Romania.
鴨嘴龍生活在6700到6900萬年前。它在恐龍谷被發(fā)現(xiàn)?？铸埞任挥诹_馬尼亞西部的特蘭西瓦尼亞區(qū)域。
Dr. Zoltan Csiki-Sava was involved in finding the diseased hadrosaur. To investigate the tumor, her team was invited to Micro-CT scan the jawbone.
佐爾坦教授參與了這次患病恐龍的研究。為了研究它的腫瘤，佐爾坦教授的團隊利用微型CT成像系統(tǒng)來觀測它的下顎骨。
“The tumor in this dinosaur had not developed to its full extent at the moment it died,” the doctor said. “[The tumor] could have indirectly contributed to its early demise.”
醫(yī)生稱：在這只恐龍死之前，其腫瘤并未發(fā)育成型。但腫瘤可能對恐龍的夭折有間接影響。
Kate Acheson is a PhD student researcher at the University of Southampton. She said the duck-billed dinosaurs were at higher risk for tumors than other dinosaurs.
凱特是南安普敦大學(xué)的學(xué)生。她表示鴨嘴龍比其他恐龍更容易得腫瘤。
The tumor is known as an ameloblastoma. That is a benign non-cancerous tumor that is found in the jaws of human and other animals.
這種腫瘤在醫(yī)學(xué)上叫做成釉細胞瘤。它是一種良性的非癌變腫瘤，在人類和其他動物身上均有發(fā)現(xiàn)。
Researchers say the dinosaur likely did not suffer any pain during the early stages of the tumor. The dinosaur died before being fully grown. Researchers are not sure if the tumor caused the death of the hadrosaur.
研究人員表示在腫瘤的初期階段，這只恐龍并未遭受很多痛苦。而他死去時，其腫瘤并未成型。研究人員尚無法確定是否腫瘤是導(dǎo)致鴨嘴龍死去的原因。
