What specialized arrangement characterized the dentition of Xenacanthus?
Answer
Herringbone pattern arranged in batteries
The teeth of *Xenacanthus* represented a significant departure from the triangular, serrated structures commonly seen in later shark groups. Instead, its dentition was highly specialized, arranged in batteries forming a distinctive herringbone pattern that functioned almost like a pincer structure. This unique dental morphology strongly suggests a specialized diet, possibly involving grasping hard-shelled invertebrates or agile prey found in its riverine or lacustrine habitat, differentiating its feeding strategy from those sharks hunting softer-bodied, larger fish.
