Avaceratops lammersi, named “Ava,” is the museum’s centerpiece exhibit. Ava was discovered in the Judith River Formation north of nearby Shawmut and is the first fossil of its kind to be discovered. This primary exhibit is not the only ancient fossils you will find in the museum, Ava is accompanied by a hadrosaur tibia and fibula, as well as a number of other dinosaur leg and hip bone fossils. The Upper Musselshell Museum also displays geological specimen such as ancient sea creatures.
Did You Know?
In 1981, Eddie Cole found the fossil remains of a relatively small ceratopsian dinosaur. The newly discovered dinosaur was named after Cole’s wife, Ava. The Avaceratops is distinguishable from other horned dinosaurs (such as the Triceratops) by its solid and shell-shaped ridge around the base of the skull. Eddie Cole believed having his fossil discovery displayed in a museum would be the highest honor, this happened with the discovery of the Avaceratops lammarsi.
