Paralligator is an extinct genus of neosuchian crocodylomorph that lived during the Late Cretaceous (Cenomanian-Maastrichtian) period in what is now the Bayan Shireh and Nemegt formations of Mongolia, approximately 96 million to 70 million years ago.
Taxonomy
Three species are recognized:[1]
- Paralligator ancestralis Konzhukova, 1954[2]
- Paralligator gradilifrons Konzhukova, 1954[2]
- Paralligator major Efimov 1981[3]
Misassigned species
"Paralligator" sungaricus, described from the Early Cretaceous Nenjiang Formation of Jilin Province, China, is based on postcranial remains consisting of a few presacral vertebrae, dorsal osteoderms, a partial left femur, and the proximal part of a left tibia and fibula.[4][5] However, the type material is too fragmentary to be considered diagnostic, and the species is a nomen dubium.[6]
