Borealosuchus originated from a comprehensive reassessment of Leidysuchus, a genus historically burdened with taxonomic ambiguity. Through this systematic revision, four previously classified Leidysuchus species were reclassified as Borealosuchus, with additional species subsequently recognized. This mid-sized crocodilian lineage reached impressive proportions, with B. acutidentatus as the apex form, measuring up to 280 centimeters and featuring a 36-centimeter skull. Remarkably, Borealosuchus numbered among the crocodile genera that endured the K-T extinction boundary, which eliminated dinosaurs, pterosaurs, and marine reptiles. This resilience, paralleled by genera including Dyrosaurus and Brachychampsa, underscores how crocodilians' distinctive physiological and ecological attributes positioned them to weather the catastrophic conditions that extinguished other reptilian groups.
