Borealosuchus was established through a systematic revision of Leidysuchus, a taxonomically problematic genus. Four species previously assigned to Leidysuchus were reclassified within Borealosuchus, with two additional species subsequently identified. This intermediate-sized crocodile achieved notable proportions, with B. acutidentatus specimens measuring up to 280 centimeters and featuring skulls approximately 36 centimeters in length. Borealosuchus exemplifies crocodilian resilience, having survived the Cretaceous-Paleogene extinction event that eliminated dinosaurs, pterosaurs, and ichthyosaurs. This survival capacity, paralleled by Dyrosaurus and Brachychampsa, underscores the physiological and ecological advantages that permitted crocodilians to persist through mass extinction while other reptilian groups disappeared.
