科学家在怀俄明发现了罕见的少年恐龙木乃伊,包括第一批已知的爬行动物蹄,它们保存在陆地上,软组织完好无损。 Scientists found rare juvenile dinosaur mummies in Wyoming, including the first known reptile hooves, preserved on land with soft tissues intact.

科学家在怀俄明州发现两个特别保存的少年恐龙木乃伊, Scientists have discovered two exceptionally preserved juvenile dinosaur mummies in eastern Wyoming, including the first known juvenile duck-billed dinosaur with detailed soft tissue impressions. 这些化石保存在由微生物帮助形成的薄粘土层中,暴露出皮肤纹理、尾刺和蹄子——在任何爬行动物或陆脊椎动物中标记第一只已知的蹄子。 Preserved in a thin clay layer formed with microbial help, the fossils reveal skin textures, tail spikes, and hooves—marking the first known hooves in any reptile or land vertebrate. 与传统木乃伊不同的是,这一过程发生在土地上,对先前关于如何进行这种保护的假设提出了质疑。 Unlike traditional mummification, this process occurred on land, challenging prior assumptions about how such preservation happens. 这些发现于2025年10月23日发表在《科学》上, 对恐龙的解剖、成长和行为提供了难得的洞察力, 强调在化石狩猎中寻找软组织印象的重要性。 The findings, published in Science on October 23, 2025, offer rare insights into dinosaur anatomy, growth, and behavior, emphasizing the importance of searching for soft tissue impressions in fossil hunting.
