Spike, the 'American' dinosaur that stars in a millionaire auction: How much does it cost? Where to see it?
Found in South Dakota three years ago, the million-dollar dinosaur is part of the collection 'Groundbreakers: Icons of our Time'. A selection of pieces that "reflect the groundbreaking discoveries and achievements of the 20th and 21st centuries."

Dinosaur auction in 2020.
Sixty-eight million years ago it walked the Earth. Today it's on sale...for at least $4 million. Christie's auction house announced the historic auction of the dinosaur Spike for December.
What kind of dinosaur is Spike?
It is a caenagnatid, a species discovered in 1940. Its members lived mainly in the Late Cretaceous (100.5-66 million years ago). It is the last period inhabited by dinosaurs, so it is considered one of the last species to walk the Earth.
They inhabited mostly in North America, remains have been found both in Canada (Alberta) and the United States (Texas, Utah). Mexican researchers claim to have found them in Coahuila, Mexico. Although to a lesser extent, they also roamed Asia.
Bipedal and with beak-like jaws, they "were first recognized for their gracile, elongate manus, and their distinctive mandibles," the latter according to a group of Canadian researchers in Histology of Caenagnathid (Theropoda, Oviraptorosauria) Dentaries and Implications for Development, Ontogenetic Edentulism, and Taxonomy.
Spike, one of a kind
Discovered in South Dakota in 2022, it is composed of 100 fossil bones ("beautifully preserved," according to its seller).
It measures nearly two meters tall (199.5 cm) and is almost as long as it is wide (198.5).
According to Christie's, a "rare marking on Spike's wrist" could serve as further evidence of the recent discovery that the species was "heavily feathered."
The British company claims its product for sale is an "exceptionally preserved" specimen of a species for which few traces are possessed.
Selling price
Spike is the first caenagnatidae at auction, according to Christie's. The company estimates its price between 3 million and 5 million pounds, or between 3.9 million and 6.5 million dollars.
Its final cost will however be defined on December 11, when the auction begins at 4 pm (GMT).
