电影《侏罗纪公园》讲述了科学家用DNA复制恐龙的故事,这个令人惊叹的想法也许在未来会成为现实。日前,美国科学家从一具7000万年前的霸王龙化石中发现了软组织,并看见血管和细胞结构。这具霸王龙化石于2003年在美国蒙大纳州被发现,且保存较好。科学家在对化石的一节腿骨进行研究后,发现在骨腔里存在罕见的化石矿物质沉积体。在经过脱矿物质处理后,剩下的是柔软、透明且富有弹性的赭色软组织,在显微镜下甚至可以看到血管和细胞结构。到目前为止,科学家还没否定有从这具7000万年前的恐龙化石中获得恐
The movie “Jurassic Park” tells the story of scientists replicating dinosaurs with DNA, and this amazing idea may come true in the future. Recently, American scientists found soft tissue from a 70-year-old Tyrannosaurus fossil and saw blood vessels and cell structures. This Tyrannosaurus fossil was discovered in Montana in the United States in 2003 and is well preserved. After studying a fossil legbone, scientists found that there are rare fossil mineral deposits in the bone cavity. After demineralization, the soft, transparent and resilient ocher soft tissue remains, and even blood vessels and cell structures can be seen under the microscope. So far, scientists have not yet denied that there are 70 million years ago from the dinosaur fossils fear
