Sinamia

Fossil specimen

Sinamia is an extinct genus of freshwater amiiform fish which existed in China, Japan, and possibly South Korea during the Early Cretaceous period.

Description

Sinamia liaoningensis

Sinamia liaoningensis is a very large fish and has a much more podgy body form than the other species of the genus but still resembles the bowfin.

Sinamia kukurihime

Sinamia kukurihime is very similar to the modern-day bowfin. A pyriform-shaped gular has been described for two isolated ossifications of Sinamia kukurihime, whose outline resembles that of K. phattharajani, except for the smooth posterior margin of the first.
