In our 171st episode, we got to chat with Sabre Moore, director at Carter County Museum in Ekalaka, Montana. Since starting work at Carter County Museum, Sabre has expanded the museum, worked with other museums for outreach, and established the annual Dino Shindig. Follow her on Twitter @Sabre_Moore and Carter County Museum on Facebook and Twitter.
Episode 171 is also about Bactrosaurus, a hadrosauroid whose name means “club lizard.”

The dinosaur of the day: Bactrosaurus
- Hadrosauroid that lived in the Cretaceous in what is now China
- Name means “club lizard”
- Name refers to the club-shaped neural spines on some of the vertebrae
- Described by Charles W. Gilmore in 1933
- One of the earliest known hadrosauroids from Asia
- Gilmore found six specimens in a bonebed
- Skull fragments and postcranial fossils (including limbs, pelvis) have been found of at least 12 individuals (juveniles and adults), found in a bonebed
- Type species is Bactrosaurus johnsoni
- Another species is Bactrosaurus kysylumensis, which is also known as Cionodon kysylumensis (a dubious genus based on partial fragments, described by Edward Drinker Cope in 1874)
- A third species is Bactrosaurus prynadai, which was originally Tanius prynadai (not many bones have been found)
- About 20 ft (6 m) long, and weighed about 2,400-3,300 lb (1.1-1.5 tons)
- Originally thought to not have a crest, but a later study found what looks like the base of a crest in early development (that was partially preserved)
- A 2003 study found evidence of tumors, both benign and cancerous ones, in Bactrosaurus skeletons (may have been because of environmental factors or genetic)
Over 900 dinosaur genera have been discovered:
- 325 theropods
- 261 sauropodomorphs
- 315 ornithischians
