🔬 Regional vs. Global Diversification: What do the fossils really say?
🔹 76% of plate-level turnover comes from immigration & local extirpation, not pure speciation/extinction.
🔹 Regional diversity signals are strongly skewed by local sampling, preservation, and geology.
🔹 Bottom line: Global analyses are still vital for uncovering true macroevolutionary patterns over deep time.
