Leurospondylus
Leurospondylus was a plesiosaur, a long-necked marine reptile that lived in the Late Cretaceous period. It swam in rivers and estuaries in what is now Alberta, Canada. Scientists think it may have spent its early life in brackish water.1

ເລື່ອງໜ້າຮູ້ມ່ວນໆ
The only known fossil of Leurospondylus is a juvenile that was about 2 meters long. Adults may have been much larger.1
Its name means 'smooth vertebra' because its backbone bones were flat and wider than they were long.1
Leurospondylus lived in brackish water (a mix of fresh and salt water) in rivers and estuaries. This is unusual because most plesiosaurs lived in the open ocean.1
When it was first described in 1913, Leurospondylus was thought to be the last known plesiosaur fossil. Its species name 'ultimus' means 'last' in Latin.1
Scientists are not sure which family Leurospondylus belongs to. Its vertebrae look like those of pliosaurs, but its shoulder and hip bones resemble those of elasmosaurids.1

ໄຂຄວາມເຊື່ອຜິດ
ຄວາມເຊື່ອຜິດ: Leurospondylus was a dinosaur.
ຄວາມຈິງ: Leurospondylus was a plesiosaur, a marine reptile that lived in the sea and rivers. Plesiosaurs are not dinosaurs.1
