Trinacromerum
Trinacromerum was a fast-swimming marine reptile that lived in the Late Cretaceous seas. It used its long flippers like paddles to chase small fish. Even though it looked a bit like a dolphin, it was actually a plesiosaur, not a dinosaur.14

Prettige feite
Trinacromerum's long flippers helped it swim very fast, and scientists think it moved like a 'four-flippered penguin'.1
Its name means 'three tipped femur', which refers to a bone in its hip that had three points.1
Trinacromerum had 46 vertebrae in its spine, including 20 in the neck, 3 in the chest, and 23 in the back.2
Fossils of Trinacromerum have been found in rocks that were once the bottom of a shallow sea that covered central North America.4
It lived from about 106 to 66 million years ago, during the Late Cretaceous period.4
Some scientists once thought Trinacromerum was the same as another plesiosaur called Dolichorhynchops, but now they are considered different.2
Mees gevraagde vrae oor Trinacromerum
?How big was Trinacromerum?
About 3 meters (9.8 feet) long. That is roughly the length of a small car.13
?What did Trinacromerum eat?
It ate small fish. Its teeth were shaped for catching and holding slippery prey.13
Mite-breker
Mite: Some people think Trinacromerum was a dinosaur because it lived in the sea and had flippers.
Waarheid: Trinacromerum was a plesiosaur, a marine reptile, not a dinosaur. Dinosaurs lived on land and had different body shapes.1

- Trinacromerum was first named by Francis W. Cragin in 1888 from fossils found in Kansas, USA. Later, more fossils were found in Canada and other parts of the USA.14
- Steeds omstrede
- Scientists still debate whether some fossils belong to Trinacromerum or to its close relative Dolichorhynchops, because their skeletons are very similar.2
