Mauriciosaurus
Mauriciosaurus was a short-necked plesiosaur that swam in the warm seas of Mexico 90 million years ago. It had a streamlined body and four flippers, and its fossil is so well preserved that scientists could see its skin and muscles!14

Datu dibertigarriak
Mauriciosaurus is the first complete polycotylid plesiosaur ever found in Mexico.1
Its fossil preserves soft tissues like skin, muscles, and even scale-like structures, which is extremely rare for plesiosaurs.1
The body shape from the preserved soft tissues suggests it swam at speeds similar to modern leatherback turtles.1
It lived during the Early Turonian stage of the Late Cretaceous, about 93.9 to 89.8 million years ago.4
The fossil was discovered in 2011 by workmen in a limestone quarry near Vallecillo, Mexico.1
Mauriciosaurus had a flipper span of 1.15 meters (3.8 feet), making it a relatively small plesiosaur.2
Mauriciosaurus: gehien egindako galderak
?How big was Mauriciosaurus?
About 1.9 to 2.1 metres long, with a flipper span of 1.15 metres. It was a relatively small plesiosaur.31
?What did Mauriciosaurus eat?
Scientists don't know for sure, but as a polycotylid plesiosaur it likely ate fish and other small marine animals.3
?Could Mauriciosaurus swim fast?
Yes. Its body shape and soft tissues suggest it swam at speeds similar to modern leatherback turtles, making it a fast swimmer.31
?Is Mauriciosaurus a dinosaur?
No. Mauriciosaurus is a plesiosaur, a marine reptile that lived in the sea, not a dinosaur.3

- Mauriciosaurus was named in 2017 by Frey and colleagues based on a nearly complete skeleton found in 2011 by quarry workers in Vallecillo, Mexico. The species name fernandezi honors Mauricio Fernández, a Mexican paleontology enthusiast.1

- Scientists are still debating exactly how Mauriciosaurus used its flippers to swim, and whether its skin patterns were for camouflage or display.1
