Tiny, long-armed dinosaur leads to rethink of dinosaur miniaturization
The real surprise, though, came when researchers realized that Alnashetri wasn’t a highly specialized, late-stage Alvarezsauroid. Instead, despite living in the Late Cretaceous, it occupied an early-branching position among earlier, basal members of the clade. This combination of tiny size and early-branching status fundamentally breaks our previous model of how these animals evolved. If the … Read more
