Classification
editPhylogenetic analysis recovers Taikicetus as a basal thalassothere more primitive than Cetotheriidae and Balaenopteroidea.[1]
Description
editTaikicetus is distinguished from other closely related thalassotheres by an anteriorly swollen short zygomatic process (length vs width of the zygomatic process; high triangular coronoid process; and weak angular process, which does not reach as far posterior as the mandibular condyle; outline of suture between maxillae and palatines forming a posteriorly pointing V-shape, convex lateral edge of supraoccipital convex in dorsal view, tip of postglenoid process in lateral view pointing ventrally, and outline of postglenoid process distinctly wider than high in anterior or posterior view.[1]
