First Dinosaurs from Saudi Arabia

Dinosaur remains from the Arabian subcontinent are exceedingly rare, and those that have been documented manifest indeterminate affinities. Consequently the discovery of a small, but diagnostic, accumulation of elements from Campanian-Maastrichtian (~ 75 Ma) deposits in northwestern Saudi Arabia is significant because it constitutes the first taxonomically identifiable dinosaur material describ...

Feathered dinosaurs, flying dinosaurs, crown dinosaurs, and the name “Aves”

The taxon name “Aves” is currently used for several different clades, a situation that violates the fundamental nomenclatural principle that, to minimize ambiguity, each taxon name should refer to a single taxon. To clarify this situation, we explore some general issues concerning the properties of the three classes of phylogenetic definitions, including: how names can be tied to clades through...

Dinosaurs

How have anoles evolved such diverse morphologies? This is an exciting time in anole biology because recently the genome of the green anole, Anolis carolinensis, was completely sequenced (http://www.broad.mit. edu/models/anole/). The completion of an anole genome opened a new avenue of research into the genetic changes that accompany adaptive radiation. Researchers would like to know how many, ...
