Nano Keeps on Slipping, Slipping…
So much has been written about Nanotyrannus, a catch-up article is hardly necessary. Indeed, many have been written, some published. The history of the name, and of the specimen that underlies it, is well-known. It behooves us, instead, to look … Continue reading
Wrench in the Works of Head Attitude
The orientation of the head for standardized anatomical comparison is important for biological and paleontological analysis. It influences anatomical direction, description, the relationship of soft-tissue, study of behaviors such as feeding by the orientation of muscles versus gravity, and so … Continue reading
