The early Paleozoic was a transformative interval in Earth history, shaped by major macroevolutionary events including the Cambrian Explosion, the Great Ordovician Biodiversification Event (GOBE), and the Late Ordovician Mass Extinction (LOME). Traditional understanding of these events is largely based on a single, aggregated global biodiversity curve, which masks the complex dynamics of individual clades. Here, we deconstruct this global narrative by analyzing speciation, extinction, and diversification patterns for 12 major fossil groups representing multiple ecological guilds using data from the Paleobiology Database and a process-based approach. Our results reveal complex and heterogeneous diversification dynamics that challenge several long-standing views of early Paleozoic macroevolution. Specifically, we demonstrate five key findings: (1) Both the Cambrian Explosion and the GOBE were prolonged radiations, not brief "explosions", sharing a dynamic of high initial speciation followed by biodiversity accumulation even as rates declined. (2) Despite their similar dynamics, they were fundamentally distinct events driven by different taxonomic groups, with the GOBE's true onset occurring in the Miaolingian-earlier than traditionally recognized. (3) The "Furongian Biodiversity Gap" is an artifact of poor preservation and the faunal dominance of trilobites, not a genuine extinction event. (4) The LOME was a prolonged, 5-million-year crisis with a dual nature, exhibiting a gradual "press" phase in the Katian followed by a catastrophic "pulse" phase in the Hirnantian. (5) The subsequent Silurian recovery was a slow and taxonomically uneven process, lacking a rapid, widespread rebound. Collectively, these findings provide a new, high-resolution evolutionary framework for the early Paleozoic, highlighting that major transitions in the history of life were the composite result of the heterogeneous and asynchronous histories of many individual clades.
