Molecular evidence for the hadrosaur B. canadensis as an outgroup to a clade containing the dinosaur T. rex and birds
Molecular analysis of collagen sequences from an 80 million year old hadrosaur B. canadensis and a 68 million year old dinosaur T. rex suggest strongly that B. canadensis is an outgroup to a …

Ancient fossil specimens of extinct species are genetically more distant to an outgroup than extant sister species are
There exists a remarkable correlation between genetic distance as measured by protein or DNA dissimilarity and time of species divergence as inferred from fossil records. This observation has prov…

Functional aspects of titanosaur osteoderms
Though titanosaur osteoderms are not common findings, these elements are recorded widely in Gondwana and part of Laurasia. This assembly known by the date offers few resources for studies on the ec…
