ichthyosaur n.(pl. ichthyosauria ) 【古生物學...

ichthyosaurus

The area where it was found had been a deep tropical bay during the jurassic period . the world ' s relatively shallow seas between 230 million and 65 million years ago contained several large animals , such as the plesiosaur with a 20 - foot neck and the giant ichthyosaurs that could be 75 - feet long 報道說,在2 . 3億年至6500萬年前,世界一些淺海地區曾生活著一些體型巨大的動物,如脖子長達20英尺約合6 . 01米的蛇頸龍以及身長可達75英尺約合22 . 86米的巨大魚龍等。

But these factors do not account for the interesting question of how there came to be such a concentration of pregnant ichthyosaurs in a particular place very close to their time of giving birth 但是這些事實不能解釋這個令人感興趣的問題,就是為什么在一個特殊的靠近他們出生的地方如此的集中了這么多懷孕的魚龍。

They included such beasts as giant ichthyosaurs that might have reached 25 meters in length and plesiosaurs with seven - meter - long necks reminiscent of the fabled loch ness monster in scotland 這些動物包括有著25米長龐大身軀的魚龍和讓人想起蘇格蘭尼斯湖怪獸故事的有著七米長脖子的蛇頸龍。

Ichthyosaurs had a higher chance of being preserved than did terrestrial creatures because , as marine animals , they tended to live in environments less subject to erosion 魚龍比起陸地的動物有更大的幾率被保存下來,因為它們作為海洋動物常生活在腐蝕性較小的環境中。
