Determining scapular position is a major issue in reconstructing the skeletal systems of extinct quadruped archosaurs and mammals, because the proximal portion of the scapulae has no direct skeletal joint with the vertebrae or ribs. When quadrupeds stand or walk, their trunk is suspended between the forelimbs by the serratus muscles, which arises from the(More)
BACKGROUND The paleoecology of desmostylians has been discussed controversially with a general consensus that desmostylians were aquatic or semi-aquatic to some extent. Bone microanatomy can be used as a powerful tool to infer habitat preference of extinct animals. However, bone microanatomical studies of desmostylians are extremely scarce. (More)
Cladistics is most prevalent method of phylogenetic reconstruction in the field of vertebrate paleontology, where it has been useful to overcome the weak points of previous evolutionary taxonomy and numerical phenetics. Its primary aim is to divide characters into two categories, old and new, and to bundle together taxonomic groups by their common derived(More)
