Albertosaurus older "Gorgosaurus libratus" (sometimes called "Albertosaurus libratus"; see below). These two species are the only described albertosaurines; other undescribed species may exist. Thomas Holtz found "Appalachiosaurus" to be an albertosaurine in 2004, but his more recent unpublished work locates it just outside Tyrannosauridae, in agreement with other authors. The other major subfamily of tyrannosaurids is the Tyrannosaurinae, which includes "Daspletosaurus", "Tarbosaurus" and "Tyrannosaurus". Compared with these robust tyrannosaurines, albertosaurines had slender builds, with proportionately smaller skulls and longer bones of the lower leg (tibia) and feet (metatarsals and phalanges). Below is the cladogram of the Tyrannosauridae based on the phylogenetic
The Bones the Scottish Mountaineering Club ("SMC") as one of 34 Furths, which is a mountain above in elevation, and meets the other SMC criteria for a Munro (e.g. "sufficient separation"), but which is outside of (or "furth") Scotland; which is why The Bones is sometimes referred to as one of the 13 Irish Munros. The Bones' prominence qualifies it to meet the Arderin classification, and the British Isles Simm and Hewitt classifications. The Bones is not in the MountainViews Online Database, "100 Highest Irish Mountains", as the prominence threshold is over . The Bones The Bones (), at high, is the
