据称，1989 年 11 月 2 日，阿根廷科学家在安第斯山脚下发现了世界上最早的两条恐龙化石。这些化石形成于 2.3 亿年前，据推测，恐龙应是当时的大型食肉动物，生活在南美洲。
这些化石是由阿根廷科学家在安第斯山发现的，当时他们正在寻找恐龙足迹。他们在岩石中发现了这些化石，并且认为这是迄今为止发现的最早恐龙化石。这些化石非常小，只有 2.3 亿年前的生物才能留下如此微小的痕迹。
根据科学家的描述，这些恐龙长约 2.5 米，重约 100 公斤，有两只脚和长长的脖子。它们的头像鸟的头，前肢短而粗壮，有很长的爪子。科学家们认为，这些恐龙可能是早期恐龙中的一个新品种，或者是一种从未见过的类型。
此次发现是在阿根廷进行的，那里是恐龙时代的中心。科学家们认为，这些化石将有助于我们更好地了解恐龙时代的生态和环境。此外，研究这些化石也将有助于我们更好地了解人类起源和演化过程。

Title: Argentina discovers earliest dinosaur fossils

The story:
On November 2, 1989, Argentine scientists discovered what is believed to be the earliest two dinosaur fossils ever found. These fossils, which date back 230 million years, were found in the Andes Mountains in Argentina. The scientists were searching for signs of dinosaur tracks when they stumbled upon the bones. They believe that these fossils are the earliest examples of dinosaurs found so far.
According to scientists, these dinosaurs were about 2.5 meters tall and weighed around 100 kilograms. They had two legs and a long neck. Their head was 相似 to that of a bird, and their claws were long and sturdy. Scientists believe that these dinosaurs were a new species or a type that has never been seen before.
This discovery was made in Argentina, where the dinosaur age was centered. Scientists believe that these fossils will help us better understand the ecosystem and environment of the dinosaur age. In addition, studying these fossils will also help us better understand the origin and evolutionary process of man.
