For the first time ever, scientists have discovered a tumor in the remains of a dinosaur. 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. 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. 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. 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. 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. 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. 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. I'm Anne Ball.

He was born with a deformed right leg.
The child has a deformed leg.
2.That is a benign non-cancerous tumor that is found in the jaws of human and other animals.
It wasn't cancer, only a benign tumour.
Yet even in its weakened condition, the country has the capacity to assert benign economic leadership—should it choose to.
人类历史上，科学家首次在恐龙的遗骸中发现了肿瘤。英格兰南安普敦大学的研究人员发现一只恐龙的下颚发生变形 。这只鸭嘴龙形体小于正常的恐龙 。是鸭嘴型的恐龙 。鸭嘴龙大约生活在6700万年到6900万年前 。是在所谓的“恐龙山谷”中发现的 。该山谷位于罗马尼亚西部的特兰西瓦尼亚区域 。佐尔坦教授参与了这只生病恐龙的研究 。为了研究它的肿瘤，佐尔坦的团队利用微型CT成像系统来观测下颚骨 。医生称，这只恐龙将死之时，其肿瘤并没有完全发育成型 。但肿瘤可能对恐龙的夭折有间接影响 。
凯特是南安普敦大学的一名博士学生。她表示，这种鸭嘴型的恐龙比其他恐龙更容易得肿瘤 。这种肿瘤学名为成釉细胞瘤 。这种肿瘤是良性肿瘤，不会致癌，在人类和其他动物身上均有发现 。研究人员称，这只鸭嘴龙在得肿瘤初期并没有遭受很大的痛苦 。而它死去时肿瘤还没有完全成型 。研究人员尚无法确定是否是这个肿瘤导致了这只恐龙的死亡 。感谢收听安妮为您发回的报道 。
