What type of massive predator was Xiphactinus in terms of skeletal classification?
Answer
A predatory bony fish (Osteichthyes)
Xiphactinus is explicitly identified as a massive, predatory bony fish. This places it within the Osteichthyes group. The text emphasizes the noteworthy achievement of a bony fish reaching such a dominant predatory niche in the Late Cretaceous oceans, suggesting that despite the typical skeletal rigidity associated with bony fish compared to sharks or reptiles, Xiphactinus evolved specialized traits to manage its diet. Its classification as a bony fish is central to understanding the biomechanical adaptations required for its immense size and feeding strategy.
