What is the approximate translation of the genus name *Xenacanthus*?
Answer
Foreign spike
The name *Xenacanthus* carries a specific meaning derived from Greek roots, translating roughly to "foreign spike." This nomenclature is a direct acknowledgement and descriptive reference to the genus's most unusual skeletal feature: the distinctive, backward-pointing spine originating from the head region. This feature was perceived as strikingly unusual or 'foreign' when compared to the standard shark anatomy known at the time of its classification, particularly when contrasting it with the standard placement of spines on the dorsal fins of other shark groups.
