给我讲一个关于恐龙的故事。
1.65亿年前，地球上生活着一种体型庞大的恐龙——布鲁塔龙。在一场突如其来的火山爆发中，布鲁塔龙被熔岩覆盖，但它的化石得以保存至今。科学家通过对其化石的研究，了解到了这种恐龙的生活习性和外貌特征。

One story about dinosaurs:

165 million years ago, there lived a massive dinosaur called Brontosaurus. During a sudden volcanic eruption, Brontosaurus was covered by lava, but its fossil was preserved up to today. Scientists have learned about the lifestyle and physical features of these dinosaurs through the study of their fossils.
