3. Diapsid_divergence（双颞骨分歧）：这是古生物学中的一个概念，描述的是双颞骨类爬行动物和其它类爬行动物之间的分化。

4. Diapsid_palaeontology（古生物学中的双颞骨）：研究双颞骨的古生物学研究涉及到这些动物的骨骼、行为、生态和进化等方面。

5. Diapsid_triassic（二叠纪晚期双颞骨）：这是古生物学中的一个时期，包括了二叠纪和三叠纪的交界，是爬行动物和哺乳动物发展的重要时期。

6. Diapsid_fossils（双颞骨化石）：这些化石是研究古生物的重要证据，可以帮助我们了解过去生物的形态和生活方式。

7. Diapsid_skull（双颞骨头骨）：这是爬行动物和鸟类中常见的骨骼结构，可以帮助我们了解这些动物的生理和进化关系。

8. Diapsid_classification（双颞骨分类）：这是古生物学中的一个分类系统，可以帮助我们理解生物的进化关系和分类地位。

9. Diapsid_pterosaurs（翼龙）：这是一种双颞骨类的爬行动物，它们有翅膀和喙，被认为是现代鸟类的近亲。

10. Diapsid_extinction（双颞骨灭绝）：这是古生物学中的一个事件，发生在约二叠纪晚期，导致了许多生物的灭绝，包括许多双颞骨类的爬行动物。

总的来说，Diapsid这个词在古生物学中有着重要的意义，它不仅代表了一个重要的分类系统，也帮助我们理解了生物的进化关系和灭绝事件。

Diapsids: An Ancient Lineage in Paleontology

Diapsids are an extinct group of animals that thrived during the Paleozoic era. These creatures, characterized by their unique features and anatomical structures, played an important role in the evolution of their contemporaries and left a lasting impact on the world of paleontology.

Diapsids were diverse in their appearance and lifestyles, ranging from fish to amphibians and reptiles. Some species were able to adapt to different environments, allowing them to thrive in diverse habitats. Their adaptations and abilities allowed them to compete with other species for resources and space, leading to the radiation of numerous diapsid lineages.

Diapsids were also important in the development of modern-day organisms, as they provided a stepping stone for later evolution. Their characteristics and traits were later adopted by other groups of animals, leading to the evolution of more advanced forms. Today, we can learn valuable lessons about the evolution of organisms and the environment from studying diapsids, and their fossils continue to provide valuable insights into the history of life on Earth.
