What specific anatomical structure does the specific epithet *pronelkocamerus* reference?

Answer

The unique internal structure of its enormous vertebrae involving hollow chambers

The specific epithet *pronelkocamerus* provides a precise description linking the name directly to the fossil evidence. This term translates roughly to 'with forward-curving hollow chambers.' This naming choice is highly significant because it immediately directs paleontologists to the most diagnostic feature of the type specimen: the internal architecture of the vertebrae. These vertebrae display specialized internal modifications, specifically large pneumatic hollows, which challenged prior assumptions about how large sauropods constructed their massive bones for weight reduction and structural integrity.
