Methodology/Principal Findings: Here we describe two new, co-occurring ceratopsids from the Upper Cretaceous Kaiparowits Formation of Utah that provide the strongest support to date for the dinosaur provincialism hypothesis. Both pertain to the clade of ceratopsids known as Chasmosaurinae, ...
Over the years, tens or hundreds of thousands of dinosaurs have been found. Today we have descriptions of more than 1,000 species of dinosaurs (see:Complete dinosaur database) and each year more and more of them. We live in a golden age of discovery. Still, hardly anyone realizes that i...

We'll never know ifTyrannosaurus rexwas particularly fiercer or scarier than other, less-popular tyrannosaurs likeAlbertosaurusorAlioramus—or even whether it hunted live prey or spent most of its time feasting on already-dead carcasses. Whatever the case, there's no question thatT. rexwas a ...
One suggestion is that placental mammals (mammals that give live birth and have a placenta) became abundant in the mountains, because they no longer competed with dinosaurs. Later, the mammals escaped these regions and went into the tropics, where they drove dinosaurs to extinction. There are pr...
With patience, Zanno has successfully searched the rocks of central Utah for over a decade. The fona, the smallest plant-eating dinosaur that lived underground, is one of several new species found in Utah's Mussentuchit Flat area. "That's one of the most outstanding things about fiel...
