New T-Rex Species Discovered in New Mexico (cool!)


I guess this is another chapter in Only in New Mexico!

Ten years ago or so there were stories about a T-Rex being discovered in the northern part of the state, probably near Philmont.  Guess they were true!  (What is so really pathetic is that The Pink Flamingo took one look at the name and wondered if there was a New Mexico connection.)

It is quite obvious the new species of T-Rex, Bistahieversor sealeyi, has some serious facial differences from a “regular” T-Rex.

“…Fossils from Bistahieversor (pronounced: bistah-he-ee-versor) were discovered in New Mexico back in 1998, and after many years of studying the bones, the paleontologists just announced the findings as a new genus and species, which they detail in the January issue of the  Journal of Vertebrate Paleontology.

To the untrained eye, Bistahieversor looks like most of its tyrannosaur relatives, but many subtle features, especially in its skull, set it apart.

“When we take all these features together, it’s clear that we have something different than what’s been seen before,” said Thomas Carr, a professor at Carthage College in Wisconsin, who studies tyrannosaurs and co-authored the paper.

The scientists based their conclusion on one main specimen, consisting of a complete adult skull and partial skeleton. This bipedal carnivore was about 29 feet (9 meters) long, with a head the size of a washing machine, and would have weighed at least a ton, Carr said. Bistahieversor was thus quite a bit smaller than its T. rex cousin, which had a head about 5 feet long and weighed around 6 tons, said Thomas Williamson, a curator of Paleontology at the New Mexico Museum of Natural History, who also was involved in the research.

The researchers also unearthed a “teenager” of the species, along with a few bones from another adult.

Bistahieversor shares a few characteristics with more advanced tyrannosaurs, like the T. rex, but also has many, more primitive features. The findings give the researchers insight into the evolution of this dinosaur linage, helping them understand when particular features may have arisen….”
