Boverisuchus
A small, hoof-toed crocodyliform that likely hunted on land.
Boverisuchus is an extinct genus of planocraniid crocodyliforms known from the early to middle Eocene (Ypresian to Lutetian stages) of Germany and western North America. It was a relatively small crocodyliform with an estimated total length of approximately 2.2–3.6 metres (7.2–11.8 ft).

Reader's Guide
Boverisuchus is significant as a well-preserved example of a terrestrial crocodyliform from the Eocene, a time when many crocodyliforms were aquatic. Its hoof-like toes, long limbs, and ziphodont teeth indicate it was adapted for running and hunting on land, likely preying on terrestrial mammals. The teeth were so similar to those of theropod dinosaurs that they were initially mistaken for dinosaur teeth, leading some paleontologists to believe non-avian dinosaurs survived the Cretaceous–Paleogene extinction event. The North American species B. vorax is known from the Bridger Formation, where stomach contents indicate it preyed on the tapiroid Helaletes, and it coexisted with large predatory mammals such as mesonychids and oxyaenids.
Did You Know?
- Boverisuchus had hoof-like toes, suggesting it lived more on land than in water.
- Its teeth were ziphodont—laterally compressed, sharp, and serrated—and were initially mistaken for theropod dinosaur teeth.
- The North American species B. vorax is known from stomach contents to have preyed on the tapiroid Helaletes.
Frequently Asked Questions
What is Boverisuchus?
Boverisuchus was a small, hoof-toed crocodyliform placed in the family Planocraniidae, represented by the type species Boverisuchus magnifrons. It stands out among its crocodyliform relatives for its compact build and terrestrial adaptations.
How big was Boverisuchus?
This animal measured roughly 2.2 to 3.6 metres (about 7.2 to 11.8 feet) in total length, placing it firmly in the smaller end of the crocodyliform spectrum.
Where and when did Boverisuchus live?
Fossils attributed to Boverisuchus come from Germany and western North America, spanning the early to middle Eocene (Ypresian through Lutetian stages). Its two-continent distribution makes it a useful marker for Eocene biogeography.
How did Boverisuchus hunt?
Rather than ambushing prey from water like modern crocodiles, Boverisuchus was a small, hoof-toed form that most likely stalked or chased prey on land. Its planocraniid skull morphology supports a terrestrial predator lifestyle.
Why is Boverisuchus important to paleontology?
It offers one of the clearer windows into small, land-adapted crocodyliforms from the Eocene, a period where such forms are otherwise scarce in the record. Finding it on two separate continents also helps trace how the Planocraniidae family dispersed across the Northern Hemisphere.
