The most exciting among these may be a new tyrannosarid, Bistahieversor sealeyi, from the Late Cretaceous of New Mexico, and a new brachiosaurid, Abydosaurus mcintoshi, from relatively older Late Cretaceous beds in Utah.

Bistahieversor, known from both adult and subadult specimens from the Kirtland Formation, would have measured some thirty feet in life.

I've been thrilled with the Bistahieversor material ever since the first formal announcement.

In the new Journal of Vertebrate Paleontology, I've made my way through several articles over the last week: "Bistahieversor sealeyi, gen. et sp. nov., a new tyrannosauroid from New Mexico and the origin of deep snouts in Tyrannosauroidea"; "A reappraisal of the origin and basal radiation of the Osteichthyes"; and "Demythologizing Arctodus simus, the 'short-faced' long-legged predaceous bear that never was."

Bistahieversor, though, gives good hints that the Big Bend tyrannosaurid was something completely new.
