A New York gallery says a 150-million-year-old complete skeleton of a dinosaur has failed to sell at auction.

Josh Chait of I.M. Chait Gallery/Auctioneers says two museums interested in the fossil failed to meet the minimum price of nearly $300,000 during the auction Saturday.

Chait says the gallery is still trying to broker a deal to sell the 9-foot-long dryosaurus fossil to a museum. Dryosauruses were two-footed, plant-eating creatures.

The auction also included the 7-foot-tall complete skeleton of a 20,000-year-old, juvenile wooly mammoth, and the fossilized skeleton of 20-foot-long marine lizard. Unidentified private collectors bought the mammoth fossil for $55,000 and the lizard fossil for $67,000.
