摘要:
There were multiple origins of metamorphosis-undergoing protaspides in trilobite evolution: within the superfamilies Remopleuridioidea, Trinucleoidea

摘要:
by examining a previous study that documented a decelerating rate of morphological evolution in pterocephaliid trilobites. Although aspects of the data set ma

摘要:
Many animals with external armour, such as hedgehogs, isopods, and trilobites, curl into a protective ball when disturbed. However, in situ

摘要:
Oryctocephalid trilobites are seldom abundant and often tectonically deformed, creating problems for robust species delimitation and compromising
