'Sea dragon' fossil is 'largest on record' “史上最大”魚龍化石體積

文字稿

科學家們稱,在德國一所博物館里“再次現身”的一塊水生爬行動物化石具有很高的研究價值,因為它是有史以來同類生物化石中體積最大的一塊。這類被稱作“魚龍”的海洋生物曾生活在距今約兩億年前的恐龍時代。這塊化石標本總長達三米多,20多年前曾在英格蘭海岸邊被人首次發現,但直至今日,還沒有人對它進行過研究。請聽報道。

Ichthyosaurs or ‘sea dragons’ were marine reptiles that swam the oceans during the time of the dinosaurs. A fossil unearthed at Doniford Bay during the 1990s is giving new insights into the life and death of the mysterious creatures. 

This ichthyosaur was a female that was pregnant at the time of death. It's one of only three to be found with an unborn baby inside. The fossil was sold to a private collector who kept it on his living room wall. It was eventually acquired by a German museum where its scientific value came to light. Scientists at the University of Manchester who examined the specimen say it's the largest of its kind at more than three metres long.

The first skeleton of an ichthyosaur was discovered in the cliffs near Lyme Regis by the Victorian fossil hunter Mary Anning. Her discovery shook up the scientific world and provided evidence for new ideas about the history of the earth. 

Two centuries on, there's still more to learn about the prehistoric sea creatures that dominated the oceans for millions of years.
