Which alternative genus name has been used for reclassified Australian *Xenacanthus* specimens?
Answer
Orthacanthus
Paleontological taxonomy is dynamic, especially when dealing with incomplete fossil remains where genetic sequencing is impossible. A known area of historical confusion involved Australian fossil material initially placed under *Xenacanthus*. Through re-examination and comparative anatomy, some of these specimens have been reclassified or grouped under alternative genus names. Specifically, *Orthacanthus* is cited as one of the names into which some previously assigned *Xenacanthus* specimens have been categorized, alongside *Paraorthacanthus*, illustrating the ongoing scientific refinement of boundaries within the Xenacanthiformes.
