Prognathodon was a giant marine lizard that lived in the oceans at the same time as the dinosaurs. It had a huge, powerful skull and strong teeth that could crush the shells of sea turtles. This mosasaur was an apex predator, meaning it was at the top of the food chain.1

Prettige feit: hierdie seereptiel het geswem terwyl dinosourusse op land geloop het. Almal noem hulle dino's, maar hulle was 'n ander tak van die reptiele.

Prettige feite

The name Prognathodon means 'forejaw tooth' because its front teeth were especially big and strong.1

One fossil of Prognathodon saturator, nicknamed 'Bèr', was found in a limestone quarry in the Netherlands and is about 12 metres long.1

Prognathodon had teeth with fine, wavy ridges near the tip that helped strengthen them for crushing hard prey like sea turtles.1

Gut contents from a Canadian specimen show that Prognathodon ate a very large fish (1.6 metres long), a smaller fish, a sea turtle, and possibly a squid-like cephalopod.1

Unlike many other mosasaurs, Prognathodon had blunt, rounded tooth tips instead of sharp cutting edges, suggesting it was a crusher of hard-shelled animals.1

The pterygoid teeth on the roof of its mouth were unusually large and showed no wear, so scientists think they were used to grip prey before swallowing it whole.1

Prognathodon fossils have been found on every continent except Antarctica, showing it lived in warm seas worldwide.2

Scientists still argue about which species belong in Prognathodon, because many fossils are incomplete and look different from each other.1

Mees gevraagde vrae oor Prognathodon

?Was Prognathodon a dinosaur?

No, Prognathodon was a marine lizard, not a dinosaur. It belonged to the mosasaur family, which lived in the oceans at the same time as the dinosaurs.1

?How big was Prognathodon?

Prognathodon was one of the largest mosasaurs. Different species reached different sizes: P. giganteus was about 10 metres (33 feet) long, P. currii about 11 metres (36 feet), and P. saturator about 12 metres (39 feet).1

?What did Prognathodon eat?

Prognathodon was an apex predator that ate hard-shelled prey like sea turtles, as well as large fish and possibly squid. Gut contents from one fossil included a 1.6 metre long fish, a smaller fish, a sea turtle, and a possible cephalopod.1

?Could Prognathodon crush shells?

Yes, Prognathodon had massively built jaws and blunt, rounded teeth with wavy ridges that helped it crush hard prey like sea turtle shells. Its bite was stronger than any other mosasaur.1

?Where was Prognathodon found?

Prognathodon fossils have been found in North America, Europe, Africa, the Middle East, and New Zealand. One famous specimen nicknamed 'Bèr' was discovered in a limestone quarry in the Netherlands.1

?When did Prognathodon live?

Prognathodon lived during the Late Cretaceous period, from about 84 to 66 million years ago. It went extinct at the same time as the non-avian dinosaurs.1

Mite-breker

Mite: Some people think Prognathodon was a dinosaur.

Waarheid: Prognathodon was not a dinosaur. It was a mosasaur, a type of marine lizard that lived in the sea.1

Vir dino-kenners

Wetenskaplike naam: Prognathodon
Benoem deur: Dollo 18892
Groep: Mosasourusse
Familie / klade: Mosasauridae2
Klassifikasie: Mosasauroidea2
Ouderdom van die rotse: 100 tot 62 miljoen jaar (Cenomanian / Danian)2
Rotsformasies: Bearpaw Shale, Torme, Gulpen2
Lande: VSA, Marokko, Spanje, Swede, Frankryk, België2
Fossielrekords: 94 in The Paleobiology Database2
Ontdekking: Prognathodon was first named by Belgian paleontologist Louis Dollo in 1889, based on fossils found in Belgium. There was some confusion because Dollo first called it 'Prognathodon' but later used the name 'Prognathosaurus' in his papers.1
Steeds omstrede: Scientists are still debating which species truly belong to Prognathodon, because many fossils are incomplete and show different features.1
