Borealosuchus

Borealosuchus (meaning "northern crocodile") is an extinct genus of crocodyliforms that lived from the Late Cretaceous to the Eocene in North America.

[2] B. formidabilis is particularly well-known, represented by the remains of many individuals from the Wannagan Creek site in North Dakota.

[5] Borealosuchus was a mid-sized crocodyliform, with B. wilsoni measuring approximately 3.2–4.5 metres (10–15 ft) long.

Fossils of this species were found in the Inversand Company Marl Pit of Gloucester County, New Jersey.

[8] Although some earlier phylogenetic studies proposed Borealosuchus to be a member of Crocodylia,[8][9] recent studies are now recovering Borealosuchus as a basal eusuchian not belonging to Crocodylia,[10][11][1] as shown in the cladogram below:[1] † Hylaeochampsa † Allodaposuchidae † B. sternbergii † B. acutidentatus † B. formidabilis † B. threensis † B. wilsoni Caiman Melanosuchus Paleosuchus Alligator Crocodylus Mecistops Osteolaemus Gavialis Tomistoma
