Paleontologist have named it Daspletosaurus horneri (in honor of Montana paleontologist Jack Horner!) and published a short description in a new scientific paper (available for free). The genus Daspletosaurus “frightful lizard” was first described from another species (Daspletosaurus torosus) that lived earlier and was found in Alberta in Canada. The new species D. horneri differs in a number of small ways from D. torosus, but may, in fact, be a direct evolutionary descendent of the earlier Alberta species, a process called anagenesis.
