Additional Information

Amecephalus, was a distinctive trilobite characterized by its unusually wide and flattened pygidium (tail shield), which often exceeded the width of its cephalon (head shield). This feature, combined with its generally smooth exoskeleton and relatively small eyes, suggests a benthic (bottom-dwelling) lifestyle, likely in muddy or silty marine environments. Its name reflects these prominent features, with "amphicephalus" referring to the seemingly similar size of the head and tail in some specimens, and "laticaudum" directly translating to "wide tail." This trilobite provides valuable insights into the diversity of morphological adaptations within the Trilobita class during its geological range.
