Description:
Annamitella liexiensis is a trilobite species discovered in the Cambrian strata of Western Hunan, South China. Trilobites, an extinct group of marine arthropods, are common fossils from this period, and Annamitella liexiensis contributes to our understanding of the diversity of trilobites during the Cambrian explosion. Fossils of Annamitella liexiensis, like other trilobites, provide valuable information about early marine ecosystems, biogeography, and evolutionary patterns. The specific morphological characteristics and stratigraphic context of Annamitella liexiensis help paleontologists to reconstruct the ancient environments and the relationships between different trilobite species.

Rhombampyx yii trilobite from the Middle Ordovician, Meitan Formation, Zunyi, Guizhou, China.
The distinct oval/rhomboid dome where the anterior needle spine meets the head is the highly inflated glabella. It is slightly compressed but shows the distinctive bulbous shape unique to raphiophorids.
You can clearly see a thin, straight line pointing straight up from the top of the glabella. This is the base of the median snout spine.
The two elongated cheek spines can be seen on either side of the body. In life, these spines flared outward to stabilize the animal or deter predators, but post-mortem movement or burial compaction has curved it around the cephalon.
