How did the relatively small size of *Amargasaurus* benefit its ecological niche compared to contemporaneous titanosaurs?
Answer
It allowed it to specialize as a ground-level feeder, reducing competition
Its smaller size and low browsing style meant it occupied a specific niche as a ground-level feeder, reducing direct competition with the very large herbivores that occupied the generalist, bulk-feeding role.
