Taxonomy
Tritodynamia globosa was named by Karasawa (1990). Its type specimen is MFM9033 and is a 3D body fossil. Its type locality is Yamanouchi, which is in a Burdigalian shallow subtidal siltstone in the Akeyo Formation of Japan.
It was recombined as Asthenognathus globosa by Schweitzer and Feldmann (2001) and Schweitzer et al. (2010).
