fejeliksuch

Fejeliksuch is a genus of extinct crocodyliform belonging to the family Doratosaurs, known primarily from fossils discovered in Late Jurassic to Early Cretaceous deposits. The genus was first described in 2018 based on skeletal remains found in the North American region, notably in the Sundance Formation of Wyoming.

Fejeliksuch is characterized by a moderately elongated skull with distinctive cranial features, including a robust snout and specific arrangements of teeth suited for a piscivorous (fish-eating) diet. The dental morphology reveals several incisiform and sharp, conical teeth, indicative of its adaptation to capturing slippery prey in aquatic environments.

The fossil record suggests that Fejeliksuch inhabited freshwater and coastal environments, likely playing a role as an apex predator within its ecosystem. Its body size is estimated to have been around 3 to 4 meters in length, comparable to other small to medium crocodyliforms of its time.

Phylogenetic analyses position Fejeliksuch within Doratosaurs, a group of semi-aquatic crocodyliforms that thrived during the Late Jurassic period. The discovery of Fejeliksuch contributes valuable insights into the diversity and evolutionary history of crocodyliforms in North America during the transition from the Jurassic to the Cretaceous.

As of current knowledge, Fejeliksuch is known from limited fossil material, and ongoing research aims to better understand its morphology, ecology, and evolutionary relationships within Crocodyliformes. Its discovery highlights the richness of Jurassic and Cretaceous terrestrial and freshwater faunas in North America.
