A baby Mosasaur skeleton is expected to make $64,000-80,000 in a sale of fossils and natural history at Auctionata.
It will take place in New York on April 19.
The Mosasaur was a large sea-dwelling reptile that swam using its snake-like tail. Their size made them apex predators. The name is a reference to the Meuse river in the Netherlands, where the first skeleton was discovered during the mid 18th century.
Auctionata explains: "This excellent specimen is 60% complete with a few built up areas to complete the skeleton, and is situated on a tall stand, making the mosasaur a beautiful, 3D display piece."
The present specimen dates to the late Cretaceous period, around 73m-65m years ago. It was found in Morocco's Oulad Abdoun Basin region.
